To solve any problem you have. To solve any problem you have. So let us begin to decisions. So let us begin to decisions. In my past sessions, In my past sessions, I was able to cover some of the I was able to cover some of the basics of earthquake engineering basics of earthquake engineering and then we moved into IS1890 and then we moved into IS1890 part one which is the mother code part one which is the mother code for Indian standard earthquake. for Indian standard earthquake. So before we start we need to So before we start we need to understand that India is proud understand that India is proud to strong earthquake seeking to strong earthquake seeking and hints art quick resistance and hints art quick resistance design is very very essential. design is very very essential. So IS1893. So IS1893. Bought one code is providing an But one code is providing an earthquake map which is based on earthquake map which is based on the maximum intensities at each the maximum intensities at each location as recorded from the damage location as recorded from the damage service of the past earthquake service of the past earthquake and and taking into account the moon taking into account the unknown magnitude and known epicenters, magnitude and known epicenters. assuming all the conditions being Assuming all the conditions being average and tectonics and lithologies average and tectonics and lithologies are also being considered in that one, are also being considered in that one, so it's very important that so it's very important that we follow this particular. we follow this particular. Code I just wanted 90 part one Code I just wanted 90 part one and there are some methodologies and there are some methodologies that we need to follow. that we need to follow. So today I will be discussing on So today I will be discussing on equivalent static analysis and this equivalent static analysis and this particular type of analysis Watt you particular type of analysis Watt you should consider and what and what should consider and what and what are the things that you need to do. are the things that you need to do. In stack pro that will be discussed. In Stackpoole that will be discussed. So today I will start with So today I will start with some of the basics things. some of the basics things. So introduction to art quickly distances So introduction to art quick list and are in and then I will move into. design and then I will move into you know, You know, the equivalent static the equivalent static methodology and methodology and discussions on discussions on IS189 three 2016 para IS189 three 2016 para meters in meters in Statpro Connect edition stature connect edition minimum minimum based share criteria dealing based share criteria dealing with with the underground structures and the underground structures and then then we will come to a conclusion why we will come to a conclusion why this static analysis is is necessary this static analysis is is necessary for the building like structures. for the building like structures. So before we begin, So before we begin, you know the past earthquake being you know the past artquake being some of the scary thing for us. some of the scary thing for us. So if you look into the pictures, So if you look into the pictures you you can understand if you're building is, can understand if you're building is, you know, is collapse like anything, you know the is collapse like you will be scared. anything you will be scared. So this is another picture so you This is another picture so you can see one of the water tank is brutally can see one of the water tank is totaly being collapsed in earthquake being collapsed in earthquake and and you know a parking stand is you know a parking stand is being being collapsed so it gives. collapsed so it gives it gives us a It gives us a good amount of you know good amount of you know or encouragement or encouragement that we come up with that we come up with a good art a good earthquake resistant structures quake resistant structure that can that can withstand the major earthquake. withstand the major earthquake. So if we move forward we need So if we move forward, we need to understand that the to understand that. The structure that we will be designing. structure that we will be designing. We are expecting no structural damage. We are expecting no structural damage. Dude, Dude, in case we have got the frequent in case we have got the frequent checking and we can even even checking and we can even even for the moderate checking, for the moderate checking, we can expect some of the non stop. we can expect some of the non stop. I mean damage in the non structural I mean damage in the non structural elements and in case of a severe which is elements and in case of a severe which is eventually an infrequent seeking there is no. eventually an infrequent seeking there is no. There is really a structural damage There is really a structural damage in elastic deformation in the. in elastic deformation in the. The lateral load listing elements The lateral load listing elements will be there, will be there, but we will ensure that there is no collapse. but we will ensure that there is no collapse. So we understand that design approach So we understand that design approach adopted in the standard standard is adopted in the standard standard is to ensure the structural causes at to ensure the structural causes at least minimum strength to withstand least minimum strength to withstand the minor earthquake. the minor earthquake. We call it as a design basic earthquake We call it as a design basic earthquake and which occur very frequently, and which occur very frequently, you know and. you know and. That image and it will be able to That image and it will be able to resist moderate earthquake without resist moderate earthquake without significant structural damage, significant structural damage, and you know, under the. and you know, under the. In sea level of earthquake, Game sea level of art quake maximum maximum considered earthquake level. considered earthquake level. We'll ensure that there will be no collapse. We'll ensure that there will be no collapse. So even we move forward, So even we move forward, we need to understand that design. we need to understand that design. We will come up with the force We will come up with the force which we call as a design lateral which we call as a design lateral force with which we will analyze force with which we will analyze our structure an will design. our structure an will design. Apart from that, Apart from that, you know. you know. The structure that we will be designing The structure that we will be designing should have a good configuration. should have a good configuration. Should have sufficient strength. Should have sufficient strength. Sufficient stiffness, Sufficient stiffness, duct Ality Redundancy And if these duct Ality Redundancy And if these are called the five Golden Rules of are called the five Golden Rules of a systemic design and we need to a systemic design and we need to ensure that the structure should have ensure that the structure should have these things while you are designing. these things while you are designing. So coming to the design lateral force method, So coming to the design lateral force method, this is an part of it. this is an part of it. I mean, it is equivalent static analysis. I mean, it is equivalent static analysis. So what we're doing is that So what we're doing is that we are calculating a factor. we are calculating a factor. AH. AH. Or AV uhm, Rev uhm, you know, you know this particular factor is this particular factor is consisting of some other factors consisting of some other factors of for any international standard, of for any international standard and it is clubbed with zone factor, and it is clubbed with zone factor, important factor and essay by G which is important factor and essay by G which is the design spectral acceleration even for. the design spectral acceleration even for. Particular and considered that an if Particularly, consider that an if you're considering the static analysis, you're considering the static analysis, there will be one value of SVG Becausr there will be one value of SVG Becausr. we are considering one mode into the We are considering one mode into the analysis and in the denominator we have analysis and in the denominator we have a factor called R&R is a particular a factor called R&R is a particular factor by which we are allowing to reduce factor by which we are allowing to reduce the force considering the fact we are the force considering the fact we are considering that ality an overstrength considering that ality an overstrength an also in denominator we have the an also in denominator we have the factor 2 which is bringing down the. factor 2 which is bringing down the. In C level to the DB level. MC level to the DB level. So we can understand the the seismic So we can understand the seismic hazards hazard in India in India is in seismic in India in India is in seismic prone prone zone and in Zone 4 danzon five are zone and in zone for Danzon five are termed as most CVS soul and we need to termed as most CVS soul and we need to think for a special type of Design in think for a special type of Design in those and those things are specifically those and those things are specifically mentioned in Rs 1893 part one 2016. mentioned in Rs 1893 part one 2016. So if we are thinking of So if we are thinking of this ? S 1893 part one, this ? S 1893 part one, this is the mother code for earthquake this is the mother code for earthquake engineering in India and it has engineering in India and it has got five different part. got five different part. Part one deals with provisions, Part one deals with provisions, general provisions and buildings. general provisions and buildings. So you can understand it provisions for the So you can understand it provisions for the building will be covered into that one. building will be covered into that one. And we have the revision of And we have the revision of this code after 2002, this code after 2002, and then if you think for what are the new, and then if you think for what are the new, we can see that we have got two different we can see that we have got two different response spectrum curve to be used response spectrum curve to be used for the static and dynamic analysis. for the static and dynamic analysis. Specifically the response spectrum Specifically the response spectrum analysis and the damping could should be analysis and the damping could should be considered as 5% for the all the buildings. considered as 5% for the all the buildings. So this particular picture So this particular picture is already known to you. is already known to you. So let us move further and we So let us move further and we have a two methods of analysis. have a two methods of analysis. As per clause number six, As per clause number six, point 4.3 or fires, point 4.3 or 5 S monitoring three part one, monitoring three part one, we have got equivalent static analysis we have got evil in static analysis an as well as dynamic analysis. an as well as dynamic analysis. So in order to differentiate what So in order to differentiate what should be the choice of your analysis. should be the choice of your analysis. First, First, if you want to go for a static analysis, if you want to go for a static analysis, we. we have some rules. Downloads what is that first What is that first time rule is that time rule is that there is no there is no plan and vertically regularity, plan and vertically regularity, meaning that the irregular meaning that the irregular irregularity irregularity checks that have checks that have explained. explained in my last SIGI mean it In my last SIGI mean it has to be performed rigorously, has to be performed rigorously, and if you have, and if you have, if you do not find any plan if you do not find any plan and vertically regularity, and vertically regularity, you will be in a position that you can you will be in a position that you can understand that you may have a understand that you may have a static static analysis to be performed and analysis to be performed and you have you have to ensure that first mode to ensure that first mode of vibration. of vibration dominates the response. Dominate the response. So if you look into the code, So if you look into the code, you know it clearly mentions that you know you know it clearly mentions that you know static analysis can be static analysis can be performed in the performed in the building in. building in the buildings in zone two, Buildings in zone two, which has mean height less than 15 meters. which has mean height less than 15 meters an rest you have to go An wrist you have to go for the dynamic analysis. for the dynamic analysis. For the tall buildings, For the tall buildings, response victim of the time stream response victim of the time stream method is preferable and if and method is preferable and if and another guideline that we can take another guideline that we can take from the code is that equivalent from the code is that equivalent static analysis may be performed for static analysis may be performed for the regular structure and having a the regular structure and having a time period less than .4 seconds, time period less than .4 seconds, so this is really tough. so this is really tough. And you know, And you know, we are simply not considering and we are simply not considering and we have to make sure that we don't. we have to make sure that we don't. Have irregularities into the Have irregularities into the structure structure so even considering so even considering the fact that you the fact that you know the this know the this particular IS1893 part one is. particular IS1893 part one is. Giving you some of the ideas that we are Giving you some of the ideas that we are designing our structure on the basis of designing our structure on the basis of Design and on the basis of capacity. Design and on the basis of capacity. So we have a specific time So we have a specific time period calculation essay by G period calculation essay by G calculation considering 5% damping calculation considering 5% damping and also the method of analysis, and also the method of analysis, different R factors and we have the different R factors and we have the vertical acceleration coefficient, vertical acceleration coefficient, minimum VB criteria and also the minimum VB criteria and also the protection property and for that protection property and for that if you want to think for the if you want to think for the capacity how we were ensuring that. capacity how we were ensuring that. We are just trying to avoid the We are just trying to avoid the irregularity or the irregularity irregularity or the irregularity checks should be performed unenforced checks should be performed unenforced missionary walls but wants to be modeled, missionary walls but wants to be modeled, but this is very, very strict. but this is very, very strict. I believe there will be an amendment I believe there will be an amendment to this particular specification, to this particular specification, otherwise the URL is a little bit otherwise the URL is a little bit tough to handle at this particular tough to handle at this particular point of time and even we are point of time and even we are ensuring that for open story building ensuring that for open story building share walls are placed properly. share walls are placed properly. Coming to the next one, you know. Coming to the next one, you know. There are some background that we There are some background that we considered why Wiley perform the considered why Wiley perform the equivalent static analysis or we call it equivalent static analysis or we call it as a lateral force method in Sri S 1893. as a lateral force method in Sri S 1893. So in the equivalent static So in the equivalent static method of analysis, method of analysis, it is assumed that the fundamental mode it is assumed that the fundamental mode of vibration is predominant and there of vibration is predominant and there is no mass and stiffness CD quality. is no mass and stiffness illegalities, Seesmic force are computed on the basis of seesmic force are computed on the basis of empirical equation, empirical equation and you can see that. and you can see that. The code is providing you The code is providing you with some empirical equation, with some empirical equation, and these particular equations are derived and these particular equations are derived on the basis of real on the basis of real time experience. time experience and model study, An model study which will give which will give you the lower bound you the lower bound time period time period as a result of that one, as a result of that one, the AIG, the AIG the horizon, to assist me, the horizontal seesmic coefficient in the principal plan directions, coefficient in the principal plan directions, will be the maximum one an as well as. will be the maximum one an as well as this will provide you with This will provide you with the maximum Basheer. the maximum bass share. Again, uh, what? We're doing the we Again, uh, what? We're doing the we are finding out the base year and are finding out the base year and these based here is being distributed these based here is being distributed along the height of the building. along the height of the building. And here they are not considering the And here they are not considering the distribution of mass and stiffness. distribution of mass and stiffness. The design lateral forces are The design lateral forces are obtained at obtained at each level distributed each level distributed to the individual to the individual lateral force lateral force depending on the stiffness depending on the stiffness of the of the lateral load listing element, lateral load listing element, and we considered that you know and we considered that you know there is rigid therefrom and there is rigid therefrom and rigid rigid from something that you, die from something that you, the code is simply asking you to provide the code is simply asking you to provide and and there are situations when the digital FM. there are situations when the digital FM. Will not be there, Will not be there. So, uh, the class numbers Seven point so the class numbers Seven point 6.4 6.4 or 5 S 1893 explicitly mentions of IS1893 explicitly mentions where where you have to consider the region you have to consider the region from all the flexible diaphragm. from all the flexible diaphragm. So we are coming to the most important part, So we are coming to the most important part, the equivalent static method of analysis the equivalent static method of analysis or the lateral forsman method here. or the lateral forsman method here. First of all, we're finding out the First of all, we're finding out the best chair Basheer is denoted by VB. base chair basheer is denoted by VB. It is being. It is being a It is being it is being a factor factor of two things age and WW. of two things age and WW. Is the seismic wait and we can calculate Is the seismic wait and we can calculate the seismic way tan for the age. the systemic way tan for the age. What we have said by two. What we have said by two in 2 Into essay by G. divided by our by I and I hope you Divided by our by I and I hope you all all understand what is the meaning understand what is the meaning of that ones. of that one that is a zone factor. It is a zone factor. Are is the response reduction factor. Art is the response reduction factor. I is the important factor. I is the importance factor. An essay by G which is which has to An essay by G which is which has to be be computed from the response victim computed from the response victim card. depending on the time period that is Depending on the time period that is being computed using the empirical being computed using the empirical equations provided by the code. equations provided by the code. So for the static analysis, So for the static analysis the time the time period is being calculated period is being calculated by the. by the empirical equations. By the empirical equations. Now, once we get the VB, Now, once we get the VB, we need to think for the vertical we need to think for the vertical distribution and the vertical distribution distribution and the vertical distribution is a sort of parabolic distribution is a sort of parabolic distribution that is being shown over here, that is being shown over here, which is the lateral story share key. which is the lateral story share key. Why is equal to PB into WHI squared Why is equal to PB into WHI squared divided by WH Square and where divided by WH Square and where you can see in the summation in? you can see in the summation in? Is the number of story that you have. Is the number of story that you have. So coming to the TA complete computation, So coming to the TA complete computation, T is denoted as approximate T is denoted as approximate natural fundamental time period. natural fundamental time period. Of the structure. Of the structure. And for this particular purpose, And for this particular purpose, we can see that the. we can see that the lateral load Lateral load resisting system resisting system has been categorized. has been categorized. You know we can have the moment resisting You know, we can have the moment resisting frame and the moment resisting frame. frame and the moment resisting frame. Maybe you know the steel frame, Maybe you know the steel frame, composite frame and RC frame. composite frame and RC frame, RC moment resisting frame. RC moment resisting frame. So for that one the first category of So for that one the first category of the equations are available and we the equations are available and we have the building with RC structural have the building with RC structural wall. wall and we have got the different And we have got a different approach approach to calculate the time period to calculate the time period for for that one and for the other that one and for the other building building the building with your arms. the building with your arms. The time period will be The time period will be calculated calculated by the last equations, by the last equations, so instead there is a methodology so instead there is a methodology of of doing this and we have got doing this and we have got the St the St parameter and we will be parameter and we will be distributed distributed and we will be discussing and we will be discussing on that on that one in the later slides. one in the later slides. There has been a change those who There has been a change those who are not following the amendment. are not following the amendment. So this has come into the amendment So this has come into the amendment and this is also already been and this is also already been there into in stack pro. there into in Statpro. So this particular amendments the Square So this particular amendment the Square is coming after the second bracket. is coming after the second bracket. So we have got the different So we have got the different situations where we need to compute situations where we need to compute the height of the structure. the height of the structure. We have got the State Building We have got the State Building where you know the weighted average where you know the weighted average has to be considered all. has to be considered all. Some of the scenarios provided in Some of the scenarios provided in the picture you have to consider the the picture you have to consider the height an as well as the base diamonds height an as well as the base diamonds and is something that you have to, and is something that you have to, you know, you know, make the program understand because the make the program understand because the program cannot understand anything over here. program cannot understand anything over here. So here we are. So here we are. Considering few facts that we will Considering few facts that we will be simply dealing with be simply dealing with these particular things. these particular things. Instead flow and for that one Instead flow and for that one the Statpro doesn't have any the Statpro doesn't have any any artificial intelligence. any artificial intelligence. So what you have to do is So what you have to do is that we have some para meters. that we have some parameters. It is a parameter driven Hughes. It is a parameter driven Hughes. The parameter in order to tell The parameter in order to tell the program what is the height the program what is the height of the building DX and easy to. of the building DX and data. What is the best dimension What is the best dimension X and set directions. X and set directions. So we will be discussing on So we will be discussing on that one in the later slide. that one in the later slide. And we have got detailed are And we have got detailed are factors. factors and here just one thing An here just one thing you you have to keep it in your mind. have to keep it in your mind. Now there nowadays there has been Now there nowadays there has been a tendency to go for you know a tendency to go for you know post tensioning slabs or post post tensioning slabs or post tensioning part into your building tensioning part into your building and for those cases the art factor and for those cases the R factor has been prescribed by the code. has been prescribed by the code. So you can also get that particular So you can also get this particular thing from the thing from the thing from the thing from the generate option into the stack pro. generate option into the stack pro. Design vertical acceleration coefficient. Design vertical acceleration coefficient. You know we can, uh, in the last webinars. You know we can. In the last webinars also have Also, I have demonstrated that we can go for demonstrated that we can go for the the vertical acceleration consideration. vertical acceleration consideration. You know the seismic forcing vertical You know the since before seen vertical directions in Zone 4 in Zone 5. directions in Zone 4 end zone 5, It is mandatory. it is mandatory. You know, You know if you have irregular if you have irregular building building in terms of vertical or plan, in terms of vertical or plan, you have to go for the consideration you have to go for the consideration of vertical acceleration coefficient. of particle acceleration coefficient. It is mandatory for the bridge It is mandatory for the bridge. A structure for the long span structure for the long span and the and the structure which has the structure which has the horizontal horizontal overhang of the structural overhang on the structural element or the other subsystem. element or the other subsystem. How we're doing that one? How we're doing that 141893 Not for 1893. The coefficient will be, the coefficient will be, you know, you know, the structure is very stiff the structure is very stiff in in vertical direction, vertical direction, so 2 third will be considered into so 2 third will be considered into the vertical detection. the vertical detection and one And one important thing under important thing under any case, any case the essay by G is 2.5. the essay by G is 2.5. We have got the consideration We have got the consideration of minimum basheer criteria, of minimum basheer criteria, so whatever be there may be sure so whatever be there may be sure depending on the zone you have to depending on the zone you have to check that one with the minimum check that one with the minimum based share criteria and the based share criteria and the clause number Seven point 2.2. clause number Seven point 2.2. Simply explain this particular thing here. Simply explain this particular thing here. One point has to be considered that One point has to be considered that we are expecting something over here we are expecting something over here important factor should should be important factor should should be multiplied with the row you know. multiplied with the row you know. I mean we till now we don't have any. I mean we till now we don't have any. You know the amendments from You know the amendments from the Code Committee, the Code Committee, but you know if you think for the but you know if you think for the international code this is there so anyhow, international code this is there so anyhow, these particular minimum based share these particular minimum based share criteria provided by the code criteria provided by the code is is being implemented in stack pro. being implemented in stack pro. So talking about we are straight So talking about we are straight away moving into the stack pro, away moving into the stack pro, so we understand that in our day-to-day so we understand that in our day-to-day basis jobs that pro use our only tool. basis jobs that pro use our only tool. You know it is a versatile tool. You know it is and versatile tool. You can do any model, You can do any model, any of the structure, any of the structure and if you and if you want to go for IS1893 want to go for IS1893 part one 2016, part one 2016, we're allowing it first you go we're allowing it. First you go to the definition after to the definition after creation creation of your model as shown over here. of your model as shown over here Seesmic definition, seesmic definition. then in the systemic definition from Then in the systemic definition from the drop down menu you choose IS 1. the drop down menu you choose IS 1. 9 three part one I mean 9 three part one I mean IS1890 part one. IS1890 part one. 2016 if you choose that one, 2016 if you choose that one, you can see a button called generate you can see a button called generate and in the generate button. and in the generate button. You will be getting, uhm, You will be getting, uhm, all the parameters in the all the parameters in the drop down list, right? drop down list, right? So these are very helpful for So these are very helpful for you and let us talk about the you and let us talk about the zone factor so zone factor can be zone factor so zone factor can be provided manually or you can use provided manually or you can use that one from generate options. that one from generate options. So if you want to use the generator So if you want to use the generated option for the zone factor, option for the zone factor, either you can choose the city either you can choose the city or you can even choose the zone. or you can even choose the zone. So depending on your dropdown So depending on your dropdown option that you have selected. option that you have selected. One factor will be simply be assigned. One factor will be simply be assigned. So as it is shown over here. So as it is shown over here. So it will help you in calculating H So it will help you in calculating H which is dead by two into I buy are which is dead by two into I buy are interested by G and there is something zed, interested by G and there is something zed, zed factory, something the zed factory, something the program will take it from here. program will take it from here. Respons adduction factor. Respons deduction factor this This is also present. is also present. You know you can either define it manually You know you can either define it manually or use it from the generate option. or use it from the generate option. If you go to the response direction If you go to the response direction vector again you have the dropdown vector again you have the dropdown option an all the conditions provided option an all the conditions in the code has been through. provided in the code has been. Has been depicted so here on, Has been depicted so here on, you know it is also used in you know it is also used in a calculation of the age, a calculation of the age, and it is in denominator. and it is in denominator. Important factor and you know, Important factor and you know, in ice 1893 part one we have an in ice 1893 part one we have an inclusion of new importance factor. inclusion of new importance factor. The important factor in the previous The important factor in the previous code or the previous version of the code or the previous version of the code was one and one point five. code was one and one point five. Now we have, with the inclusion of 1.2 Now we have, with the inclusion of 1.2 which is for the residential which is for the residential or the or the commercial building where commercial building where the more the more than two 100% people than two 100% more than 200 people it's more than 200 people staying staying on that particular structure so. on that particular structure so. You can simply define the You can simply define the important factor from, uh, important factor from, uh, from the option and then you what you from the option and then you what you can do is that you can can do is that you can simply click on simply click on generate option generate option an from the generate option. an from the generate option. You can go to the importance vector You can go to the importance vector and from the drop down you can and from the drop down you can choose that one and again it is choose that one and again it is used to calculate the age value. used to calculate the age value. So you know we have seen that the So you know we have seen that the response reduction the response victim response reduction the response victim curve that the code has provided is curve that the code has provided is on the basis of your type of soil on the basis of your type of soil be cause the soil is providing you be cause the soil is providing you with a different type of SVG value with a different type of SVG value and the soil structure interaction and the soil structure interaction is sometimes is very very helpful. is sometimes is very very helpful. And since we have got a generalized And since we have got a generalized response spectrum curve. response spectrum curve. Available for India and this Available for India and this is a dependent on two things. is dependent on two things. Damping the damping is 5% throughout Damping the damping is 5% throughout and it is also dependent on the and it is also dependent on the type of soil where the building of type of soil where the building of the structure will be constructed. the structure will be constructed So you know we have the option. so you know we have the option. We can have the hard soil, We can have the hard soil, medium soil and soft soil an for that medium soil and soft soil an for that one we will get to see some of the one we will get to see some of the para meters being generated in the para meters being generated in the seismic definition which is known as. seismic definition which is known as. Is this parameter is this one Is this parameter is this one corresponds to your heart's oil? corresponds to your heart's oil? Is a Stew corresponds to your medium. Is a Stew corresponds to your medium. Soil and ancestry correspond Soil and ancestry correspond to your soft soil. to your soft soil. So where this is used, So where this is used, this is used to consider the essay by G this is used to consider the essay by G and the value and you have to consider and the value and you have to consider the fact that you should know that I'm. the fact that you should know that I'm. Otherwise you cannot find the essay by G. Otherwise you cannot find the essay by G. So the next thing is that, So the next thing is that, uh, St parameters, uh, St parameters, so St is an important parameter, so St is an important parameter, and if you are so from my past experience and if you are so from my past experience with the Bentley, with the Bentley and specifically an specifically with stack with stack pro and I've been asked, pro and I've been asked, I've been asked many times by the user, I've been asked many times by the user, can I use and user defined time can I use and user defined time period for the static analysis? period for the static analysis? The answer to that one is no, The answer to that one is no, because our intention is to calculate because our intention is to calculate the lower bound time period and that. the lower bound time period and that. Can only be computed by using, uhm, Can only be computed by using, uhm, your empirical equations provided your empirical equations provided by the code and you know there by the code and you know there are some other methods that are are some other methods that are available with us just like your eigen available with us just like your eigen solution or model extractions method. solution or model extractions method. If you if you for any any type If you if you for any any type of building that you have. of building that you have. If you use the. Model extraction method. If you use the. Model extraction method. And even if you use this And even if you use this particular empirical equations, particular empirical equations, most of the cases even more than 99% cases, most of the cases even more than 99% cases, you will see the time period you will see the time period computed by this. computed by this. Empirical locations will be lesser than Empirical locations will be lesser than the one that you compute mathematical E. the one that you compute mathematical E. The reason behind that one, Reason beyond that one, you know we are not in a position to you know we are not in a position to model model the actual real time structure. the actual real time structure first. First. We are unsure of the stiffness We are unsure of the stiffness in the sense that the. in the sense that the. The beams and columns that The beams and columns that we're modeling is of RCC, we're modeling is of RCC, but in a software we consider that one but in a software we considered that one is of concrete and again there are some is of concrete and again there are some structural part we may take part in. structural part we may take part in. I in the lateral load transfer mechanism, I in the lateral load transfer mechanism, but we're not in a position to but we're not in a position to model at one in our mathematical model at one in our mathematical model using our software. model using our software. So coming back to the St parameter, So coming back to the St parameter, you can use the St parameter from you can use the St parameter from the graph or assign it manually. the graph or assign it manually. Or you can use the generate Or you can use the generate option so we have got option so we have got 45 St parameters and we will see 45 St parameters and we will see that if we have the RC Murph then that if we have the RC Murph then they still parameter should be 1. the St Perimetre should be 1. RC still composite moment. RC still composite moment resting frame. Resting kimmich will be ST2 RC still It will be ST2 RC still moment resisting building it's S moment resisting building. It's S T3 and then if it is an T3 and then if it is an building I building I mean with the share with mean with the share with structural structural walls then we have to use walls then we have to use the the SD4 and the other type building. SD4 and the other type building, Meaning that with the infield walls we meaning that with the infield walls we have to use the SD five para meter. have to use the SD five para meter. So the most important thing is So the most important thing is we have gotten you inclusion. we have gotten you inclusion. That is the St four parameter That is the St four parameter and how this should be used. and how this should be used. We have the special We have the special recommendation that this is. recommendation that this is. This will be used for the This will be used for the building with RC structural where building with RC structural where we're using the St four an the we're using the St four an the guiding equation by which the guiding equation by which the time period is being calculated. time period is being calculated. You know we have an equations You know we have an equations where we have the factors. where we have the factors. H&EWNEW is being computed by HNEWNEW is being computed by AAWI and it is also a factor of ill by HOK. AAWI and it is also a factor of ill by HOK. So how we're doing that one Watt? So how we're doing that one Watt? We're asking from you if you provide the We're asking from you if you provide the seismic definition in the seismic definition. seismic definition in the seismic definition. If you're using the F4 parameter, If you're using the F4 parameter, it is mandatory that you use the Valaria it is mandatory that you use the Wild area parameter. Parimeter an here you provide the length An here you provide the length and and the width of the wars that are. the width of the wars that are. Along the X and the directions you know, Along the X and the directions you know, but this particular world once again but this particular world once again I'm saying, is structural wall, I'm saying, is structural wall, not a brick wall or the Flyers prequel. not a brick wall or the Flyers prequel. So if we provide those date as you know, So if we provide those date as you know, in this particular model we have. in this particular model we have. You know this particular vaal information. You know, this particular wall information. And. What we're doing. And. What we're doing. We have provided that one over here and We're provided that one over here, and you can see the width of the walls you can see the width of the walls and and length of the wall is being provided, length of the wall is being provided, so in eggs directions the length by so in eggs directions, the length by height and their areas height and their areas is being computed is being computed and the submission and the submission is been provided is been provided and we are following and we are following this particular this particular equations and we equations and we find the time period find the time period and similarly and similarly for that direction this. for that direction this. It WI uh for uh, you know, It WI uh for uh, you know, for that direction, for that direction, wall is being computed individually wall is being computed individually and then it's a mission has been and then it's a mission has been computed and what we're doing. computed and what we're doing. We're finding out the time period. We're finding out the time period. So considering this particular So considering this particular fact that I'm creating, fact that I'm creating, the exhortation is .63 an the exhortation is .63 an in zed direction is .9 one, in zed direction is .9 one, but we have to be careful over there, but we have to be careful over there, the mandated and it has to be the mandated and it has to be compared with the another time period. compared with the another time period. Which is absolutely to the SD 5, Which is absolutely to the SD 5, which is 0.09 divided by root D. which is 0.09 divided by root D. So we are internally computing that one, So we are internally computing that one, and we found that 0.09 H divided and we found that 0.09 H divided by root root D is that particularly by root root word of D is that question which is providing the particularly question which is providing the lower time period than lower time period than we calculate we calculate by St four parameter by St four parameter. This particularly equations. this particular equations, So we are taking these particular so we are taking these particular time cleared into analysis and. time cleared into analysis and. If you look into the stat, If you look into the stat, out would just provide it over there out would just provide it over there you can see stand is calculated you can see stand is calculated absolutely taking this particular value. absolutely taking this particular value. So, uh, damping if you're coming So damping, if you're coming to the damping, to the damping, but I mean, but I mean it is recommended that you it is recommended that you know know you considered 5% of the damping. you considered 5% of the damping. 5% of the critical damping, 5% of the critical damping, so by default affected is 0.05 right? so by default affected is 0.05 right? But sometimes you know But sometimes you know the people we have seen. the people we have seen. The people are quite interested The people are quite interested to use a different damping apart to use a different damping apart from the damping that we provided, from the damping that we provided, so sometimes you may provide so sometimes you may provide 2% temping or 3% damping. 2% temping or 3% damping. So what will happen to So what will happen to those particular class? those particular class? We are going be cause the code We are going be cause the code is not giving you any any. is not giving you any any. You know any clue what to be done? You know any clue what to be done? Even it is very strict to use the 5% damping. Even it is very strict to use the 5% damping. So what we have done we have used So what we have done we have used table tree of older version of the table tree of older version of the code which is which is coming in code which is which is coming in the clouds number Seven point 2.4 the clouds number Seven point 2.4 you know of the latest code for the you know of the latest code for the 5% damping and if it is you know 5% damping and if it is you know anything other than the 5% damping anything other than the 5% damping so we are following the table. so we are following the table tree Three of the older version of the code of the older version of the code that is in 2002 S one 890 Part 1. that is in 2002 S 1893 part one. A 2002 code and Claws Number, A 2002 code and Claws Number, Six Point 4.2 and we have got some Six Point 4.2 and we have got some factors to be considered with the essay by G, factors to be considered with the essay by G, so we're considering that one. so we're considering that one. And if we're doing that one, And if we're doing that one, you know we have provided the you know we have provided the 2% of the damping. 2% of the damping. The essay by G is 1.395 for the 5%, The essay by G is 1.395 for the 5%, and we're modifying that one with the and we're modifying that one with the factor 1.4 as shown in the table three. factor 1.4 as shown in the table three. We're getting a value as one point. We're getting a value as one point. 9026 so we're doing that one, 9026 so we're doing that one, and this is something we have seen the and this is something we have seen the people is wanting is eager to use this one, people is wanting is eager to use this one, but you are violating the code provisions, but you are violating the code provisions, so for that one we are simply so for that one we are simply giving you a warning. giving you a warning. The warning says is it by G4S One 890? The warning says is it by G4S One 890? Two 1016 is only considered for Two 1016 is only considered for 5% 5% MP for any other value table, damping for any other value table, three of IS189 three 2002 version part three or five S 189. Three 2002 version part one or one or obviously will be used and we obviously will be used and we are are strictly giving you an instruction. strictly giving you an instruction. It is highly recommended. It is highly recommended. Do always use 5% damping as specified To always use 5% damping as specified in the current version of the code. in the current version of the code. Now sometimes and we can understand that Now sometimes and we can understand that there are some situations we may use, there are some situations we may use, we may need to use, we may need to use, you know user defined time period you know user defined time period and that particular time period. and that particular time period. Definitely for the equivalent static Definitely for the equivalent static analysis should be considered analysis should be considered following the equations and you can following the equations and you can simply provide that one in pink sand. simply provide that one in pink sand. Apisit parameter. Apisit parameter. And there are situations you know And there are situations you know you have a particular building you have a particular building where the supports in the. where the supports in the. You know you have the support, You know you have the support, which in the X direction is at the. which in the X direction is at the. I mean it is not at the I mean it is not at the same Y coordinate level. same Y coordinate level. In such a case is you know the program In such a case is you know the program will try to calculate the base dimension. will try to calculate the base dimension. And it will not be able to find that one. And it will not be able to find that one. It's it's better that you simply compute It's it's better that you simply compute the time period in the X direction and the time period in the X direction and then provide it in the PX parameter. then provide it in the PX parameter. And this is one of the scenario And this is one of the scenario which is as per the figure, which is as per the figure, five or five 1893. five or five 1893. You can see this will be one of You can see this will be one of the cases in which why do you the cases in which why do you have the state you know building? have the state you know building? So this is very critical and So this is very critical and program will not be able to handle program will not be able to handle this and we we simply expect the this and we we simply expect the user to calculate the time period user to calculate the time period and provide that exhilaration. and provide that exhilaration. Typing in providing the speaks parameter. Typing in providing the speaks parameter. Similarly for the zip direction, Similarly for the zip direction, if the Y coordinate of the supporting if the Y coordinate of the supporting the the dates direction are not in the days Jason are not in the same Y coordinate, same Y coordinate, what will happen? what will happen? Is that even the program cannot Is that even the program cannot find the base year. find the base year. Sorry, Sorry, base the base dimension and it will base the base dimension and it will fail to compute the time clear Dan. fail to compute the time clear Dan. This is the scenario where you may This is the scenario where you may have and you have to provide that one. have and you have to provide that one. We have two other parameters, We have two other parameters, dip the foundation. death, the foundation. You know this is one of the thing You know, this is one of the thing those those were using IS1893 part one who are using IS1893 part one 2000. 2002 code. The portion of the To code the portion of the structure structure which is below the ground. which is below the ground. Should be mentioned by Should be mentioned by using the DP parameter, using the DP parameter, but you know the in the present version but you know the in the present version of this particular implementation we of this particular implementation we are absolutely not recognizing the DT are absolutely not recognizing the DT parameter or we'd simply suggest not parameter or we'd simply suggest not to use the DT parameter rather Watt. to use the DT parameter rather Watt. We will ask you to do is to calculate We will ask you to do is to calculate or to provide the GL parameter. or to provide the GL parameter. GL parameter is very very GL parameter is very very simple simple and Eligio para meter. and Eligio para meter. What we do is that we provide the Y What we do is that we provide the Y coordinate of the ground level anwil. coordinate of the ground level anwil. Will it be used? Will it be used? It will be used to calculate reduce It will be used to calculate reduce age value for this portion of the age value for this portion of the structure which is below the ground. structure which is below the ground. So how we're doing it is been So how we're doing it is been explained in the next slide. explained in the next slide. So here you can understand or you So here you can understand or you can see that there is a building can see that there is a building which and some of the portion which and some of the portion of of the structure is below the the structure is below the ground ground and you have you know the and you have you know the retaining retaining walls connect to that one. walls connect to that one. And what happens is that you know And what happens is that you know the behavior of the structure, the behavior of the structure, which is above the ground and below which is above the ground and below the ground will not be the same. the ground will not be the same. Even the code has suggested a Even the code has suggested very simplified process to handle very simplified process to handle that one and Watt we do is that. that one and Watt we do is that. We're calculating the seismic wait for We're calculating the seismic wait for the structure which is above the ground, the structure which is above the ground, and we're calculating the VB which is and we're calculating the VB which is H into W and we're calculating all the H into W and we're calculating all the factors and height of the structure is factors and height of the structure is coming can be considered over here to coming can be considered over here to calculate the you know the time period. calculate the you know the time period. Um and we can distribute the seismic. Um and we can distribute the Seesmic. You know the base here in the story. You know the base here in the story share using the normal formula, Share using the normal formula which is which is above the ground and for the ground, above the ground and for the ground, which is for the structure, which is for the structure, what the portion of the structure which what the portion of the structure which is below the ground. What will happen? is below the ground. What will happen? What will happen to that? What will happen to that? Is that you know everything will be the same, Is that you know everything will be the same, but we will use an interpolation factor. but we will use an interpolation factor. AHI mean an interpolation factor AHI mean an interpolation factor, or the multiplayer. or the multiplayer. Should be applied on age and Should be applied on age and we're calculating. we're calculating. You know, You know, the portion of the weight of the the portion of the weight of the structure which is below the ground structure which is below the ground and then we are distributing it and then we are distributing it in the below the ground portion. in the below the ground portion. So as a result you can may So as a result you can may have have a condition like this. a condition like this. So how we're doing that one man So how we're doing that one man for this particular structure? for this particular structure? You know the Y coordinate of You know the Y coordinate of this particular and Y coordinate this particular and Y coordinate of the ground level is 9 meter, of the ground level is 9 meter, and we have got the 21 meter and we have got the 21 meter in height of the building. in height of the building. So what we're doing is that you. So what we're doing is that you. What we're doing is that we What we're doing is that we are simply finding out the, are simply finding out the, you know, the first of all, you know, the first of all, we're finding out the time period. we're finding out the time period. Time period is being calculated Time period is being calculated as a time period. as a time period. He's been calculated by zero .075 there is He's been calculated by zero .075. There is a steep. STHTI mean depending on the SD Depending on the AST parameter, an H to the Power .75, parameter an H to the Power .75, so the height is you know 21 meter. so the height is 21 meter we are. We're calculating the. Calculating the, uh, you know the time period of the structure You know the time period of the structure and from the depending on the type of soil, and from the depending on the type of soil, the essay by G is one by TA and it's. the essay by G is one by TA and it's. Value is coming out to be 1.359 this portion. Value is coming out to be 1.359 this portion. This will be an reduced and you know This will be an reduced and you know what we're getting zapped by what we're getting zapped by two into. two into a buyer interested by G. I buy your intuition by G so you So you are getting this particular are getting this particular value value which is been deported over here which is been deported over here and for the underground structure. and for the underground structure. What is happening is you know we are What is happening is you know we are applying the multiplication factor. applying the multiplication factor. If it is, you know this particular. If it is, you know this particular. Interpolation factor if the Interpolation factor if the structure is at 30 meter level, structure is at 30 meter level, the factories .5 and then the factories .5 and then if if it is at ground level, it is at the ground level, there is no reduction and what there is no reduction and what will be the value at nine meter will be the value at nine meter is being calculated an that has is being calculated an that has been used as an age reduced and been used as a each reduced and it is being deported over here. it is being deported over here. Here we are also allowing you to use. Here we are also allowing you to use. You know value, different value of SVG. You know value, different value of essay by G. Even this is something that is Even this is something that is be sometimes be helpful for you. be sometimes be helpful for you. You know if you want to. You know if you want to, If you want to provide some value of the if you want to provide some value of the essay by G so directly to the program. essay by G so directly to the program. So what you can do is that you can So what you can do is that you can simply use the essay parameters so they simply use the essay parameters so they say by G value will be taken from. say by G value will be taken from. That is a parameter that you provide and age The is it by limited that you provide and age will be calculated will be calculated depending on that one. depending on that one. Again, we talked about, you know, Again, we talked about, you know, the different damping factors, the different damping factors, and we're using the table three and we're using the table three of the older version of the code. of the older version of the code. This particular damping factor This particular damping factor can be Simply put as an improved can be Simply put as an improved to the structure at 22222 to the to the structure at 22222 to the software in the DF parameter, software in the DF parameter, which is the multiplying factor for essay. which is the multiplying factor for essay. So you can use that one. So you can use that one. So even for the factors you should So even for the factors you should use is from the table tree of use is from the table three of the older version of the code, the older version of the code, which is that ability of which is I is that ability of IS1890 part one 2002. IS1890 part one 2002. So what we're getting is a veggie modified So what we're getting is a veggie modified essay by G four 5% multiplied by DF. essay by G four 5% multiplied by DF. Is the final value and we talked Is the final value when we talked about the height of the building. about the height of the building, It's it's sometimes very difficult, it's it's sometimes very difficult, you know to find out the height of the you know, to find out the height of the building building for a software be cause we do for a software be cause we do not not have the boundary conditions modeled. have the boundary conditions modeled. So if you have some portion of the So if you have some portion of the structure which is underground, structure which is underground, and even if you have the stable building, and even if you have the stable building, so these are the situations so these are the situations where you specifically need to. where you specifically need to. You know the calculate the You know the calculate the height of the structure, height of the structure, so height of the structure is something so height of the structure is something that I mean that sometimes is required that I mean that sometimes is required to be provided required to be taken to be provided required to be taken as an input from the user and that as an input from the user and that is that to be and that has to be is that to be and that has to be used by the HT parameter in here. used by the HT parameter in here. If you this is I mean you know you If you this is I mean you know you can see the parameter list can see the parameter list and some and some of the parameters are is of the parameters are is provided provided with the astrex Mac marks. with the astrex landmarks, so these parameters are something. So these parameters are something. Are those para meters where we are simply, Are those para meters where we are simply, you know, allowing the users to? you know, allowing the users to? Uh, you know with some default value, You know with some default value. so in case of a height of the building, So in case of a height of the building, what we're doing, what we're doing, we're finding out the lowermost Y coordinate, we're finding out the lowermost Y coordinate, which is a supported, which is a supported, which is a supported one, which is a supported one, and two the highest Y coordinate and two the highest Y coordinate of a node in the building. of a node in the building. And differences between these And difference between these two will be the height, two will be the height, but that will be wrong for some of the cases, but that will be wrong for some of the cases and that will lead to an conservative. and that will lead to an conservative. I'm very, I'm very very conservative value very conservative value of of SVG or even the best so. SVG or even the base here, so. You need to provide the HD para meters. You need to provide the HD perimetre. User defined D and what we're doing is that User defined D and what we're doing is that in the X direction and as a directions, in the X direction and as a directions, we have this DX and visit parameters because we have this DX and visit parameters because the base dimensions sometimes has to be used, the base dimensions sometimes has to be used, even you know. This DXD, even you know. This DXD, zed and DT parameters should be used. zed and DT parameters should be used. I mean in synchronization. I mean in synchronization. So here for a particular structure So here for a particular structure where St five has been provided and where St five has been provided and you know the height of the building is you know the height of the building is 15 meters based dimension is in the X 15 meters based dimension is in the extraction is to help an based diamonds direction is to help an based diamonds and instead direction is 6 meters. and instead direction is 6 meters. So in the X direction you will see So in the X direction you will see the 0.09 in 215 divided by root, the 0.09 in 215 divided by root, above 12 it's coming out as in 0.3, above 12 it's coming out as an 0.3 eight 9.97. eight, 9.97. And that is being reported over here, And that is being reported over here, and similarly in that direction. and similarly in that direction. The other thing, 0.09 in 215 The other thing, 0.09 in 215 divided by root root over of six divided by root root over of six is being provided an the time is being provided and the time period is being calculated 0.55. period is being calculated 0.55. Again, each and everything that we are doing Again, each and everything that we are doing over here we have to check the best year over here we have to check the best year that we're computing should be compared that we're computing should be compared with the I mean should be compared with the with the I mean should be compared with the minimum base share for a particular zone. minimum base share for a particular zone. And if you're the computed based here And if you're the computed based here is less than the minimum base share, is less than the minimum based here, you know the minimum based share should you know the minimum base share should be the base ship that you should use. be the base ship that you should use. So this these things is being So this these things is being simply calculated by. simply calculated by. The program and in the. The program and in the. Uh, in zone one. Uh, in zone one. The factor a factor for the zone The factor a factor for the zone one is been computed over here, one is been computed over here, which is .7 multiplied by the which is .7 multiplied by the seismic wait an divided by 100, seismic wait an divided by 100, so it's coming out to be 90.66, so it's coming out to be 90.66, so you know calculated based here is 6 so you know calculated based here is 6 foot Seven and minimum based series 90 so. foot Seven and minimum based series 90 so. Even though the Mac, the calculated You know the Mac. The calculated based shares which will based shares which will be used, the program is doing that one. be used the program is doing that one. And most importantly, And most importantly, whenever we are going for whenever we are going for a a base share calculation, base share calculation, it is mandatory that we distribute it is mandatory that we distribute it as is a story shut. it as is a story shut. The program does that one. The program does that one. So how we can? So how we can? Even if we know that if you Even if we know that if you after the analysis, after the analysis, if you click on the static system load cases, if you click on the static system include cases, it will be displayed but you have it will be displayed but you have the option to get those generated the option to get those generated forces reported in your output file. forces reported in your output file. How to do that? How to do that? One you can go to the analysis One you can go to the analysis commands from analysis and design. commands from analysis and design. Design tab, Design tab, you go to the analysis commands you go to the analysis commands and you add the command you click and you add the command you click on define commands and from the on define commands and from the analysis and print command you analysis and print command you choose the option perform analysis, choose the option perform analysis, print load data as shown over here. print load data as shown over here. So what it will do, So what it will do, it will report you know for a particular it will report you know for a particular flow water the nodes and thus story flow water the nodes and thus story share computed at that particular. share computed at that particular. At that particular floor. At that particular floor. So now we can understand from our last So now we can understand from our last discussions even we have explained you, discussions even we have explained you, what are the parameters that are what are the parameters that are to be used in a statics is weak to be used in a statics is weak analysis and how to do that one. analysis and how to do that one. But why this particular But why this particular static static analysis is required? analysis is required be cause we Becausr we have so many uncertainties have so many uncertainties while while modeling a structure in a software, modeling and structure in a software? you know we don't know what will be the You know we don't know what will be the actual stiffness and what will be the actual stiffness and what will be the value of modulus of Elasticity Evalue. value of modulus of Elasticity Evalue. And even we are not modeling some And even we are not modeling some of the portion of the structure, of the portion of the structure, so you know it may so happen so you know it may so happen that in the mathematical model that in the mathematical model that we generate to solve, that we generate to solve, you know the model extraction. you know the model extraction. Maybe you know the approximate one. Maybe you know the approximate one. So the code has suggested a check So the code has suggested a check and this particular check is and this particular check is mandatory for the building like mandatory for the building like structure while we compute the structure while we compute the beige where we compute the base beige where we compute the base share using the empirical location, share using the empirical location, which is the equivalent static method which is the equivalent static method and also with the dynamic method and and also with the dynamic method and this comparison of the base share this comparison of the base share is very very important and that is is very very important and that is why even if you go for the dynamic why even if you go for the dynamic analysis you know you need to go analysis you know you need to go for the stat at least computation. for the stat at least computation. Of the best share using the uh, Of the best share using the. the process we use as an The process we use as an equivalent static method. equivalent static method. So, uh, once again, uh, So, uh, once again, uh, you know, you know we have come up with the book we, I have come up with the book of of U IS1893 seismic analysis and this U IS1893 seismic analysis and this particular if you require if you want particular if you require if you want to purchase this particular book, to purchase this particular book, you can send an email directly to you can send an email directly to me and I will be helping you out. me and I will be helping you out.

We know we're going in a crisis We know we're going in a crisis where COVID-19 is simply, where COVID-19 is simply, I mean allowing us like anything. I mean allowing us like anything. But I believe this particular But I believe this particular session will be an interesting one. session will be an interesting one. And I hope that you will be in a position And I hope that you will be in a position to help you out with the Bentley software. to help you out with the Bentley software. Dan, I haven't won. Dan, I haven't won. See I mean I've got 1 announcement over here. See I mean I've got 1 announcement over here. So in my last session we had So in my last session we had a plan to help all of you. a plan to help all of you. All of the users who are using the Bentley. All of the users who are using the Bentley. I mean, let us software specifically I mean, let us software specifically for Statpro Connect Edition. for Statpro Connect Edition. You may find that you know they're using. You may find that you know they're using. The little bit different any you may The little bit different than you may face some problem in doing that one. face some problem in doing that one. So we had thought that we will be conducting So we had thought that we will be conducting in webinar on 3rd of April to help you out, an webinar on 3rd of April to help you out, but for this particular COVID-19 but for this particular COVID-19 spread sprayed in the community we are in the community we are postponing postponing that one and just stay tuned. that one and just stay tuned. We will be announcing those sessions We will be announcing those sessions and believe me that particular and believe me that particular session will be very very helpful. session will be very very helpful. And for those who are using. And for those who are using. Stack broke statpro. Stack broke statpro. Please update yourself to the Please update yourself to the connector nation to use this connector mission to use this particular IS1890 part one and 2016. particular IS1893 part one and 2016. I'll thank you all and have a good day, I'll thank you all and have a good day, bye. bye. Hi all, I was having some issues over Hi all, I was having some issues over here to your questions I believe I you here to your questions I believe, uh you can hear me right? can hear me right so we have noted down So we have noted down all of your questions, all of your questions you know since you know since we all are working we all are working from home and facing from home and facing some issues this some issues this particular session you particular session you know I was know I was able to explain you all the able to explain you all the things things and I think that there are some and I think that there are some questions which are not been answered. questions which are not being answered. So what I will do is that I have we What I will do is that I have we have have noted down all these questions an noted down all these questions an even even we can send the reply to you even we can send the reply to you even we we have a community known as Ben Click have a community known as Ben Click Community and where we will be posting, community and where we will be posting, you know, the answer to all your questions. you know the answer to all your questions. Just give us some time and we are Just give us some time and we are facing a really hard in India facing a really hard in India for for copied 19 I mean thread. copied 19 I mean thread. So I believe we will be in a position to. So I believe we will be in a position to. Answer all of your questions it. So all of your question it. Once again thanks. Once again thanks. All of you for joining. All of you for joining. You know the next sessions? You know the next sessions? I mean we will be sending out the I mean we will be sending out the invite is for the the next sessions and invite is for the the next sessions and here let me see one or two questions. here let me see one or two questions. If I can even answer that one Can even answer that one at at this particular part time, this particular part time. so one of the question was what So one of the question was What is is AST para meter and you know? this T parameter and know that is a And that is a particular HT parameter particular St parameter is a particular is a particular parameter which can parameter which can be used to compute be used to compute the time period the time period of the buildings of the buildings with the with with the with the RC structural wall the RC structural wall and there and there you require to input, you require to input, you know, you know the vowel length and thickness in. the vowel length and thickness in. X and the duration of the wall. Um? X and the duration of the wall. Um? Next question that I can see is uh. Next question that I can see is uh. The comparison of the question The comparison of the question on the comparison of the base. on the comparison of the base. Yet yes, the program does Yet yes, the program does the comparison of vision. the comparison of vision. Actually, if you're performing respon Actually, if you're performing respon spectrum or the dynamic analysis spectrum or the dynamic analysis then the base share from the dynamic then the base share from the dynamic analysis has to be compared with analysis has to be compared with the base share computed from the the base share computed from the static method an this particular. static method an this particular. This particular stuff, This particular stuff, or this particular operation or this particular operation is being done internally by the is being done internally by the problem and as a result of that problem and as a result of that one you will be getting this, one you will be getting this, particularly when all the response particularly when all the response quantities from the response cases will quantities from the response cases will be multiplied by this particular factor. be multiplied by this particular factor. So in my next session I will be So in my next session I will be explaining on that one in details. explaining on that one in details. Um? Um? X question that I can see. X question that I can see. What is DX Ann visit parameter and look What is DX Ann visit parameter and look into the code and even into real structures. into the code and even into real structures. There are some 10s. There are some 10s. I mean, what should be your actual Maybe one could be your actual base dimension of your structure, base dimension of your structure depending on the on the conditions so depending on the on the conditions, so the software doesn't have any the software doesn't have any information, information because in the software we because in the software we are going are going for the modeling only and for the modeling only and we're not we're not providing any other information, providing any other information. So it is imperative that the software so it is imperative that the software cannot understand what will be the actual cannot understand what will be the actual based dimension in X and they direction. base dimension in X and they direction, So we have kept that one opened for the so we have kept that one opened for the user to use DX an these at para meters. user to use DX an these at para meters. Next question. That I can have Next question. That I can have a I can see from here how to a I can see from here how to model underground part instead. model underground part instead. So basically, and how will the So basically, and how will the software know the part above the software know the part above the ground and the part will look down ground and the part will look down so it is absolutely very difficult so it is actually very difficult for the program to understand. for the program to understand. You know which post. You know which post. The round in which person The round in which person is above the ground. is above the ground. So even in the end, So even in the end, at the time of modeling we are at the time of modeling we are not doing that one or we're not doing that one or we're not providing any information. not providing any information. Rather what we're doing is Rather what we're doing is that women IS 1 eight times this week. that in IS 1 eight times this week parameter we have got a Parameter we have got a parameter called GL parameter. parameter called GL parameter. So in the GL parimeter you need to So in the GL parimeter you need to provide the Y equal 8 of the ground level. provide the Y equal 8 of the ground level, so this will be a particular So this will be a particular thing by which the program can thing by which the program can understand which portion. understand which portion. Is below the ground an above the ground? Is below the ground an above the ground? So. So. Another question is, uh, Another question is, uh, how to apply vertical based here in how to apply vertical based here in case of a building in seismic zone and case of a building in seismic zone and zone four times inside you know? zone four time zones like you know. Uh, this is, uh, a particular thing This is, uh, a particular thing that you have to do this the mandatory. that you have to do this the mandatory. So there are two parts. So there are two parts. One is you know if you want to. One is you know if you want to. You love vertical earthquake. You love vertical earthquake. If you want to consider the effect of If you want to consider the effect of vertical earthquake in in static analysis, vertical earthquake in in static analysis, since the two day session on static analysis, since the two day session on static analysis, so I will be discussing on that one. so I will be discussing on that one. So first we start. So first we start. You know first we start with the. You know first we start with the. This is Magnificent. Uh, and. This meeting Uh, and. I just wanted to see sweet definition I just wanted to see if we definition an in the IS1890 seismic definition. and in the IS1890 seismic definition. What we do is we provide the What we do is we provide the system system seismic parameters and seismic parameters and then we then we may provide some seismic may provide some seismic weight, weight but it is not required. but it is not required. If you have got the mass difference If you have got the master difference load case and now we go onto the load load case and now we go onto the load case details and we in the case details and we in the primary primary load cases what we do is load cases what we do is that we that we find the seismic load in X&Z find the seismic load in X&Z and and then we can define invite Jason then we can define invite Jackson. why being the vertical direction? Why being the vertical direction? So. So. Uh, I think we are running Uh, I think we are running out of time and you know. out of time and you know. We are we have all of your questions We are we have all of your questions so I will be answering them. so I will be answering them. Uh, and we will be posting the Uh, and we will be posting the answers involving clickability site. answers involving clickability site. So once again thank too thanks to all So once again thank too thanks to all of you vining. of you joining this particular session. This particular session B Be safe, stay at your home. Thank you. says stay at your home. Thank you.
