OK, Good morning, Good afternoon and good evening for some depending on where you are around the globe. I want to welcome everyone out to our. Insider skills special interest groups, first ad and before we get started in today's presentation. I do want to make sure. My audio and video is coming through. Loud and clearly here. So I just want to confirm that before we get started. We do have a chat window that you can. Type into just to confirm. That you can hear my audio and. Um. See my screen so if you could. Type into the chat window that would be great just to confirm and then we're going to proceed with today's presentation. I should be sharing uh uh this slide, the mean slide here for. Um. The presentation, which says Optimize Foundation design for construction costs. And time savings with. A safe and practical approach, so if you can see my screen. Then. Just please confirm that. OK, I think I think I'm OK with the. Screen sharing so let's go ahead and get started with today's presentation. And actually we're working with the new. Uh user interface today. And So what I'm going to do here. I'm going to start out with the power point slides here that you can see on the screen. And then we'll jump into our live presentation. So you should be seeing different windows on your screen right now and what you can do is you can. Actually adjust those. You can adjust those. Windows into different sizes, so here on the bottom of your screen. You should see this bar here and. That bar should allow you to view the different resources. Throughout this presentation and as I mentioned there Resizeable, there movable and you can access the resource list and also the Q&A. So we are going to have a QA session. At the end of this presentation. And so if you have questions along the way feel free to type those questions into the chat window, so this is a new. Interface if you haven't seen this before. This is what we're going to be using going forward for all of our special. Interest groups and we hope that you can take advantage of this and utilize some of them. A great features of this so. Let's jump in here. And for our today's topic we are going to be discussing. Optimizing. Foundation designs for construction costs and time savings. With a safe approach and safe and practical approach instead foundation advance. So. Before we discuss that topic. Let's talk a little bit about the special interest groups and then will jump into the specifics of what we want to talk about today. So for the special interest groups for stab their offered on the 3rd Thursday of the month. And they start at 1:00 PM Eastern Time. That's the same as New York time and we do get credit for your attendance here so if you're. Attending this presentation, you will get one professional development, our credit an we have those transcripts available on the Bentley learn server. Also, there's no cost for your attendance here, so you can just register for this online an attend at no cost. OK, now let's talk about what we want to discuss today. We have 3 main topics that we're going to cover here. And they're all related to optimizing foundation design for construction costs and time savings. Making sure that we Take into account safety an we have a practical approach, so the first topic. We're going to cover is utilizing the new. Efficient. Optimization algorithms for cost effective foundation design, So what does that mean especially that what that means is we've? Updated the software. Instat foundation events and we've. Added an algorithm which helps too. Um more efficiently optimize your foundation design, so will discuss exactly what that is, and how that works also. The second topic, we're going to cover is comparing your foundation design scenarios using automated material take off data. To achieve optimal project foundation solutions, so that sounds a little complex, but what you'll see is not that complex it's very simple. And what we've done is we've added in new. Material take off information into your foundation design report. And so now we can use that data to come out with the best scenario for our foundation. On a particular project and then the 3rd topic. We're going to cover is how do we take advantage? Of the Enhanced Foundation design calculations to maximize foundation design safety and efficiency so we want to discuss what? New enhancements, we have to the program and then how do we best use those enhancements? To come up with the best design, so those are going to be our three topics that we're going to cover today. All right now, what are some of the benefits of talking about these topics well obviously? New foundation design algorithms are going to improve the cost effectiveness for foundations in staff foundation vents that's a huge benefit. Also with the new material take off reports it gives the structural engineers that data to calculate optimal foundation designs from. A variety of scenarios. And then Lastly we can achieve an efficient and Safe Foundation design faster. Using Stab Foundation vents to incorporate soil passive pressure calculations, so this is one of the new enhancements that we've added in. Is being able to use the passive pressure calculation? To get a more efficient foundation design. OK, so let's now. We're going to switch over and jump into. Our live presentation now I'm going to stick with this PowerPoint for just a minute here because we want to discuss. The workflow the overall workflow for staad pro and Stab Foundation events. Now this is a topic that we've covered previously. So I just want to take a few minutes to explain the workflow here, so as you can see. Uh starting in staad pro. You're going to 1st. Run your analysis and design for your above ground structure and once you design. And analyze your above ground structure and then you can take all that data that all that information into the foundation program to design your foundation. So we've seen this before. And so for this particular structure. We actually have an electrical substation structure here that is going to be the above ground structure that we? We're designing and then we want to design our foundations from that, so right from our stab Pro Connect edition will be able to access. Our foundation design now when you choose. The foundation design, you can choose what loading you're going to bring over. Into the foundation program. And what support locations that you're going to bring over so in this case, we have 2 support locations. That we're going to bring in design foundations for and we have a number of low cases that we're going to bring in. OK and then from that all that data is going to transfer into our foundation program. Now the great news about what were all the topics were going to cover today? Is that if you have? Just a license for staad pro and you don't have a license for Stat Foundation advance. You can still use. The features that we're going to cover today, so that means that you can install stat foundation events and you can use your stab Pro license. Uh to do these types of foundation designs so everything we're going to cover today. Will be included with your stab Pro license, even if you don't own a license for Stat Foundation Advance? So it gives you the ability to design these foundations and optimize them. Inefficient way. OK and then once you've brought all that data into the staff foundation. Advanced solution. You will be able to design your foundation. Get your report here so you can see the detailed report with all the calculations there. And you also get your drawings created for those foundations. And then finally you can get your been model, there for your foundation so complete 3D model with the design of the pedestals. All your reinforcement. The sizing of the foundations all that information can be. Automatically generated from the foundation program so we've covered this topic in detail an if you go to our. YouTube channel on AT Bentley structural you can actually see the recording of that workflow that we've just discussed. So. Today's topic is going to actually be In addition to that Workflow and what we're going to get into now is how do we? Optimize the foundation so it's not just a simple. Uh design that is safe, but also we can consider other options and come up with the best solution. So that's our goal for today. Alright so now. I'm going to actually share my screen here. I'm actually already sharing my screen here, but We're going to jump into a model. So you can see my desktop right here, so the first thing I want to do is let's talk. About. The new Features that we've Optimized. Instead, Croinin instead foundation vents. And how that works OK, we actually have. A link to the release notes for. Stat Foundation event so we're going to be looking at the new release of Staff Foundation advance version 9.2. And we have those notes on our Bentley community page, which you can see here so the. The enhancement is that we've the the algorithm for sizing of combined footings has been improved. So that Stat Foundation advanced will produce better economically size footings by placing a higher priority on increasing the lateral dimensions before increasing the thickness. So the added benefit of the soil weight is obtained for the stability checks for service load cases so. Essentially, what they're saying is when we're we're asking Stat Foundation advanced. 2. Design our foundation in size them, then what's going to happen is. The algorithm prioritizes sizing of the foundations. In its length and width rather than its thickness, so that we can get the benefit of the. Additional soil that's going to be. On Top of the foundation to offset some of those stability checks, so for sliding and overturning will get it. Improvements there and we're going to really see how this makes a difference. Especially when we're taking into account our passive pressure OK. So. Let's continue there so. The first thing we've added here is the new algorithm for sizing the foundation. Now In addition to that enhancement that's going to automatically. Work on its own all you have to do is choose to design A compound combined foundation we've also. Updated. Our material takeoffs in the foundation program so let's go ahead and open up the foundation program and take a look at that. And we're going to run a design for our foundation. So I have a few different models were going to look at. And these models again we started in staad pro so let me. Show you that. As I go to my stab Pro XL think I already have statpro open here. And I'll open up. The actual above ground structural model. The same one we saw earlier in the power point but now let's look at it live here. In staad pro. And the reason why we want to look at this. Is because? Um understanding are loading on the above ground structure is going to help us to understand. The design for the foundation. So let's go in and open this here right. OK, so here is our. Our above ground structure here, we can see the 3D model same structure. We had before, in the PowerPoint. OK, now if we take a look at some of our loading. This is going to help us understand maybe how we should size our foundation so. Again, this is an electrical structure, electrical substation structure and so we're going to have the dead load going to have I slowed we're going to have a wind load? We have some extreme wind conditions and some other things. And then we have some combinations. So essentially we have 7 primary load cases and then we have low cases 8 through 11, which are going to be. Combinations OK, so if we take a look at some of our loading conditions here for our dead. Load we can see we have some. Concentrated loads in the self weight on the structure. I slowed are similar there. And then we have wind. And so we have wind in the X direction. And that's going to be significant. And then we're going to have wind in our. Z direction as well now, the importance of that is that? These wind loads are going to. Impact the foundation in terms of sliding and overturning so those lateral loads are going to place moments on the foundation. As well as lateral forces that are going to create sliding and overturning and we're going to have to design for that so. By understanding where those loads are acting and how they're acting we can appropriately use that information to help size our foundation. So that's why we want to take a look at this now, again after we've run our analysis, we can go right to our foundation program. And. Bring all that information into. Stat Foundation events, OK, so we've already done that step. And so now we can just open up our foundation program so the first foundation. We're going to look at. And I'm just going to go right here to open. And. Let's go to the model here that we want to. Look at OK. And so we're going to go here to our foundation, so the first model. We're going to take a look at. Um will be. Right here in this model is. A model where? We have already designed 2 types of foundations in here, so we've designed spread footings. And for the same structure, we've designed. Combine footings OK, so if we take a look at this. All right, we have. Um. All of our parameters that are already set up again, we've covered this previously another. Um. Presentation so we don't want to go through all of that again, but you're going to Add all your. Design parameters for the foundation design. And then you're going to run your analysis in design OK. Now, when you do that, it's going to produce a report for both. Uh both types of foundations so in this 1st. Um. Analysis and design that were doing were actually designing a spread footing here for each one of our column lines. So. We're looking to see what design we get based on. Our parameters that we've set up OK, so let's discuss some of those frames so you can see here. The. The detailed report that is produced an what's new in this detailed report is going to be our. Material takeoffs and this is what we're going to do now in terms of using this information to optimize the design so if I Scroll down here. You can see the detailed report that is produced. And what we've added to it here is our material take off so now. This data here is going to give us. Additional information on our foundation immediately so we know how. Much the weight of the reinforcement is going to be here for this particular design, so we can see our. Reinforcement. We can also see the weight of the pedestal reinforcement. So this is just the footing. The pedestal and then we get the total reinforcement wait there. We can also see our volume of concrete so you see the volume of the footing concrete volume of the pedestal concrete. And we get the total concrete volume. Additionally, now. We get the form work and we get the soil excavation. And backfill volumes, so this is important not only for just the material cost of designing the foundation how much steel and how much concrete. But also in terms of our construction costs how much form work do we need. What type of excavation volume? Is there going to be in how much backfill so now this is automatically? Part of your report that is produced and we can use this now to compare different scenarios, So what do I mean by that so this first design? Is 4 two spread footings so if we look at our? Um general arrangement view here and I'm going to, I'm going to choose to show. The general arrangement. 4. The current job only and I'll hit refresh so. In this scenario, we've designed a square foundation. Um for Using spread footings at each column line so that's the scenario, we chose an then. The program automatically ran through the design to optimize for the thickness and the length and the width and came up with this size, so 10 by 10. Buy 1, 1/2 foot foundation at each one of our column lines, OK, so that's. One design option another design option or another scenario would be that we have a combined footing instead of. To spread footings for the same structure. So let's go now to the combined foundation option and we can run our analysis in design for that, So what you'll see here. I'm going to have to enter in. All of your parameters the same way. You did for your spread footings and then you're just going to run your analysis and design. And again this is going to give you the material take off information. So you'll have the material take off information for your spread footings, but you also have the material take off. Information for your combined footing so now this gives you the ability to compare very quickly. And come up with the optimal solution and so that's why. That's a benefit here, so you can see. How they combine foundation is being designed here so this total foundation now is going to be 12 feet? By 16 feet there and you can you can see the layout that all of that information now if we Scroll down? Will also be able to see? The material take off here and I'm going to. I'm going to go back up. In just a minute an will see also some important information about sliding and overturning. And how we take advantage of that, so here again. We're going to have that material take off for our combined foundation 2. So this gives us real values. Real numbers for the weight of our reinforcement steel in our footing in our pedestals. And then the overall volume of concrete form work the soil excavation. So we really have all the information. We need now to make a good assessment, so we have one scenario. Where we have our square spread footings another scenario where we have our combined foundation now? How do we compare this data together? OK and so that's where we're going to use our Excel spreadsheet that comes into play. So here I've set up an Excel spreadsheet. An in this Excel spreadsheet, I have. Uh. Put in all the data that I needed for. Each particular scenario, so this far scenario is we have a square footing on the left end on the right side. Of our foundation. And so we can copy paste that material information directly from. Our. Report, an then the way we've set it up is I've just added since I know I have 2 foundations in here. I'm just going to add up the total weight. Of. Of reinforcement there. To get the design for the for both foundations, so I can compare that to the combined foundation so. Here we get those total that I used there and then we do the same thing for our combined foundation here where. We're only going to have one foundation instead of two and we have those weights there an volumes there. And then that that gives us the ability to. Compare both OK. So when we copy paste those values, so let me show you how easy it is to. Copies those values in here allowed do it for the combined foundation since we just ran the analysis on that. So right from Aarstad. Um. Foundation advance. Right from our calculation package. We can highlight this data in. In here so I'm just going to highlight this data. And then I'm going to hit control C to copy OK. I hit control C to copy then I go to my Excel spreadsheet. And this is for the combined foundation. And then I'll just hit control V to paste. OK So what it does is it paste. Right into those. Excel spreadsheet an it has all those values and then what I've done here is I've just. Put in the the total weight. The total solve added some of those up here and then on this other spreadsheet. I'm going to access that information so I've just. Chosen for this cell 2. This value equals the information on the other spreadsheet, so now I can do a quick comparison here on. These 2 different types of foundations, so it's very easy to see what's going on. So, in this first scenario. We have 2 square footings spread footings. And we have a combined foundation so here's our spread footings. And here's our combined foundation now. One thing you'll notice right away is that for the spread footings. We don't have any. Top reinforcement on the foundation, but for the combined footing. We do have Top reinforcement that's because. We're going to have bending in the. Foundation. Due to it being a combined foundation so we need that Top reinforcement, there rather than those vertical load just. Acting down and then the soil supporting. Uh that loading there, so we're going to have more reinforced steel reinforcement in the combined foundation. So there's a tradeoff there where we have our square footings versus our combined footing so we have more steel. Now what about concrete well in concrete. We actually have are using less concrete in the combined foundation and then when it comes to form work we actually have less form work. Because we're just forming around the perimeter an we have the same type of pedestals. Whereas here we're going to have to form out. Around these 2 foundations, so a little bit more form work. For the Spread footings an then. We're going to have less excavation and less backfill so. Based on this first scenario here. It's looking like even though we're going to have more steel for our combined foundation. Overall for construction cost. It's going to be a better solution going with the combined foundation so we're going to have a little bit more steel. But less everything else. OK, so that's our first scenario that we run now. Are there ways to optimize? Our. Spread footings a little bit more. And so that's where we're going to look at some other values OK, so let's go back to our. Spread footing. Job. Here so I'm going to go right here to spread footing. And so we have our calculation package for our spread footing. An here is where we can actually look at. One of another new feature in here and that is a table for our. Um. Factors of safety against. Sliding and overturning and so we've always done these calculations, but the good thing now is we highlight the controlling load cases here. So you can quickly see which low cases are controlling for. The design. For your against sliding overturning and you can see your factor of safety that you're using so as a structural engineer. I have the ability to control this factor of safety and I can see that for my. Overturning. Well, over the Factor of safety in the Z direction, however, in the X direction. I'm close to my factor safety so my factor safety is 1.5. And the actual value that I'm getting in this particular case is 2.0. So I have some room here in the Z direction because I'm well over my factor safety. But I'm getting close in the X direction, so we can consider now how we might modify our foundation. To take that information into account. For sliding were actually. In good shape here, you can see where it have factor safety of 5. In One Direction in a factor of safety of 7 in the other direction, so we're well above are. Are required factors of safety there? So now, what can we do in this scenario. Well, we actually can take advantage of the geometry of the foundation. And So what do I mean by that so here in this? Footing geometry were choosing to design the foundation or calculate the dimensions for a square foundation. And what I can do let's take a look at how we would do this. Uh in another model, I've already run the analysis and another model, so we're going to take a look at another. The other model here. And by modifying. By modifying the Geometry a little bit. We can. Let me go to this model so. I'll go to recent here. Sorry. So by modifying the geometry a little bit. Then we'll be able to. Optimize. Um our foundation and still be within the range of the factor of safety that we want. OK So what I'm doing now is I'm opening up a second model. Now the second model has the same loading information. Has all the same parameters set up but in this model? What we've done here. Is when you look at the footing geometry? We're calculating. Uh the dimensions differently, so before we had our minimum dimension for the length of the foundation that will be in the X direction. As 4 and we had the minimum dimension for the width. As for which produced a square foundation for us. But in this scenario what we're going to do is we're going to actually make the minimum. With 12 so meaning that I'm going to have a longer foundation. Um in this direction. And so it's not going to be a square any longer. It's going to be a rectangular foundation so by setting. Those dimensions differently, it will now optimize in a different way so let's look at the results of that so. Let's go here and. Run our analysis, so I'll go to. Analysis in design. And you can see how quickly. This design takes place. And it's optimizing for all the load cases that we've considered. And uh and coming up with the design. So now before we had a square foundation. If you look at our foundation now at each column line, it's rectangular so we started with the minimum dimension. For the width as 4 feet Anna minimum dimension 4. For this direction as 12 and so this is what the foundation optimized to be. So we can, we can see. Now how that compares in terms of our material usage and everything else. Um so. This is the design for the left column line an if we go to the right column line. We're going to get the same. Uh. Design there so let's go to our general arrangement during an you can see here. Now, for this scenario. We have because we're not using a square foundation anymore. We're using a rectangular foundation. This would be the layout that we come up with. Which looks like it's a little bit more efficient than what we had we used a square? Foundation design so the main difference here was modifying the minimum values for the length in the width to come up. And produce. A different. A design now let's see if we go to our calculation sheet. How this factors in? For the for our sliding overturning and it are we still. In a good range for. Um for those OK, so here. This is for? The new design. And what we'll see is that? We're still in a good range and in fact, for one of their directions. We actually have a higher factor safety now. Before for the X direction, we had a factor of safety. Of. It was 2.0 now we have 2.37. And but we took a reduction in the Z direction. But we're still OK, there, so we're at 2.79, so by changing that geometry a little bit. We still have a very safe design. And. We have made the design more efficient now by doing that and so we can easily see how these changes that we're making. Play out and then we can come up with a great solution now again we can take those material takeoffs. And compare that to the combined foundation so we already have all the information for our combined foundation. We can do the same thing here. Take this material take off. So I'll copy this value right from our. Foundation design. And. If I go back to this spreadsheet. Now we have the optimize rectangular spread footing. So we can actually just paste. This data in here. Just for example. Sorry set up I just hit control V to paste and that information is in there now. Of course information matches because I've already. Alesis and so we can see. What happens when I paste that data in? And now we can go to our scenario 2 option, which is. What if we compare our? Rectangular spread footings. 2. The combined foundation and now will see that for the combined foundation. We actually are using more steel. Reinforcement. More concrete. We still have slightly slightly less form work because again, you're going to be forming out. The perimeter of the foundations there, so it's a little bit less form work, but in terms of the. Excavation and backfill now these values are very close to one another and. In reality because these foundations are so close to one another. The actual backfill in excavation values will be very. A similar here, so we're not going to have a big difference in. The excavation an the backfill. Volumes So what does this mean this means now that are rectangular spread footings are really going to be our best. Option here we're getting a significant decrease in the concrete volume significant. Decrease in the reinforcement. Steel that we need and so. This is going to be our more optimal solution. Now. This might not be a big deal. If we're just talking about one structure at one site but if this structure. Maybe we're going to have 10 structures like this at a site or if we're going to have 100. Structures like this. And multiple sites, then this. Adds up to a major difference in what we can achieve. For a cost saving Anna construction, saving so not only materials, but construction labor an all of that. So. So we definitely can use this in a very quick and efficient way. 2. Sisar, foundations and come up with the best scenario, OK, so one other thing we want to consider here. Is that we used our material take off? We also took advantage of the algorithm? Yeah, that's was updated for the combined foundation. But now We also want to look at our passive pressure, so this is one thing that we haven't talked about, but It was it was improved in. The foundation program as well OK. So. Let's take talk a little bit about passive pressure here, so if you look at the PowerPoint now. Um we Actually have a book that discuss is foundation design. In in a very comprehensive way. And this book was published by the Bentley Institute. And we have 2 of our senior developers for Stad Apurba trip, Betty Ann also another one of our. Developers. I don't know how to pronounce his name, but you can see it's written there and. They took time to to develop this book to help people understand how to use. The Stat Foundation Advanced Program. In a very fast and efficient way an understand exactly what? Um. Each. Selection that is made in the program how it impacts your overall design, so this is a good way to learn that information so. In Chapter 5, here of the. Of the book. Um. There's some information related to passive pressure. Now we're talking about passive pressure. We're talking about when we have. Of lateral force on our structure here like we did. On on the Substation structure that lateral forces pushing the. Foundation into the soil. So since it's pushing. The foundation into the soil. There's a resistance from the soil itself, so that's our passive Earth Pressure, an what we're saying is that we can. Use that passive earth pressure to optimize our foundation if we consider that. Pressure in our design calculation now previously we didn't have the ability to consider that passive earth pressure in our design calculation. So we only relied on the cohesion and our resistance from the soil friction. And. Now. With the passive pressure, we can actually get up. A better solution that's more accurate for our different scenarios. Now there's a couple of things that you have to be careful love. And that's going to be a situation where maybe. You have. Excavated a portion of the soil. In the direction of the. Loading. So, in that case your passive pressure. Is not going to be a valid usage? Of of. Additional support for your foundation. So you want to make sure that the conditions surrounding your foundation actually match. The design parameters that you're using so this is one situation where you would not want to take into account the passive pressure. Because you've already actually excavated that soil and therefore the resistance from that soil is not going to be present. OK, so here you would just want to use your frictional force there or your cohesion of your soil. As your Resistive forces. As well as the dead load and in all of that OK. So those are some things to consider when talking about passive pressure. Now let's go jump back here in 2. Stat Foundation Advance, an will look at one other model. And this is going to be based on the same above ground structure. So. Going to be open up our last model and we're going to take a look at how you can. Activate the passive pressure for your. Isolated spread footings. Ann. One other Option that we have. So let me go to my recent. Foundations here. And this is the This is the one we want to look at. Now in this particular model. I've made a couple of different changes and we'll see how those changes play out. So. When we're talking about the passive pressure. What we've done here? Is for our isolated spread footings? Uh when you go to your sliding in overturning parameters here OK. This is where you have the option. To consider? Passive Earth pressure in your calculation, which you can also do is set your factors of safety. Again, sliding an? Overturning so you choose as an engineer at your judgment on if you need some additional factor safety now. You can increase that so 1.75 let's say. You want to. Have a higher factor safety because maybe you're going to be including this passive pressure. And you want a little bit more. Um. Taking too a little bit. Account more safety there and not be be a little bit more conservative. I'll just say just be a little bit more conservative. 'cause you are going to consider the passive pressure so you increase your factor safeties so you could if you're worried about the sliding. More than the overturning maybe you're going to make your sliding. Um. Factor a little bit higher an you can leave your overturning so right there, you can adjust as you need to. OK so that gives you the flexibility that you need. And to use your judgment as a structural engineer to consider these different scenarios to come up with the best solution. OK, so we can. I do that now the other option you can do is For Your. Footing geometry. You can actually put in offset. In the X direction, So what does this mean this means the column line does not have to be centered? On the foundation. You can offset it a distance and that's what we've done in this. Scenario here so for the left spread footing, I offset the column line. To the right. 12 inches OK and now when we do our design. We're going to see what the impact of that is an. Oh, there's one other thing I did, too. Which is I started with a different value so one other thing for the footing geometry not only did I offset the columns. But instead of the minimum. With being 12 feet, I used the minimum width of 11 feet and so now. That changes the overall dimensions, so here if we look at our foundation design. This is for the left column. I have shifted. Instead of that. Pedestal being centered on the foundation is shifted to the left there now. Why did I do that? Well, I know I'm going to have? Another foundation on the other side, so there's going to be that lateral support in there. Anyway and so I know that those foundations will be working together so this is. Something that I can take advantage now if we continue down in 2 hour. Um. Calculation package and we look at. The resistance for sliding in overturning. What you'll notice is for overturning here? We're sacrificing a little bit in the X direction. But we're gaining in. Desene directions, so we're still have a safe. We're still safe we're still within the increased factor of safety there. Uh for sliding. We're fine, we are. We have, we're not worried about the factors of safety that we're getting for sliding. And again this is taking into account that passive pressure as well. So for the overturning. Uh you can. Use all that information. And use your best judgement, there, so you can see that OK so that. Is? Basically, how we would handle that an in this particular model what I needed to do is I needed to have a different offset. For the Left Foundation versus the right foundation. So what I needed to do was set up a second job so for the first job, I'm designing for the left. Column line. And for The second I'm designing for the right column line. And so I'm going to have different offsets. 4. Each one. OK so if I go to footing geometry here. This is going to have a negative offset in the X direction. And then you can see how this foundation. Is being designed here? To be shifted the other way. OK and so it's as simple as that when I run my analysis and design. It's going to do the analysis. And size those foundations. So what we've added in. 2 Stat Foundation advance. Our features that help give you more control over the foundation more control over safety. And better ability to optimize based on the real world scenario that you're working with. For your foundations. And so that's what we want to talk about today, so you can see all of this information is. Being calculated. In your foundation. Report here so that's the great thing that it is being calculated in your foundation report and we're doing. Handling all that number crunching for you. You can take the material take off data here and. Use that information to come up with the best scenario for your foundation design. And then you also have your been model that's produced. As well as your drawings that are produced so you're really getting everything you need in a very fast and efficient. Way starting with your above ground structure, taking that information to your foundation so you have the accuracy of. All the loading coming over from stab pro coming into your foundation. Design as a starting point, having all the geometry laid out correctly and then doing all the checks that are required by the code. And having control over your design, so this is how we've tried to give the engineer the structural engineer. The flexibility they need but also the accuracy and the transparency to understand the calculations understand what's being done. And take advantage of that OK, so at this point we're going to take questions and answers we're going to have a QA session. I'll take the questions. And I'll give you an answer, so if we have any questions that we've been typing into the chat window. We want to actually review those questions so. We have about 5 minutes left to answer any questions and. Let me see if I can pull up. The quite well here it is so I'm reviewing some of these questions now. Give me a second. To do this as best I can I'm still learning. Um how to do this and looks like we have. Um. 2 unanswered questions here. Let me see if I can make the screen a little bit better, so we have. A question from a mere. Um from USA Structural. How does stat foundation advance distinguish between clay? And sand soils for sliding overturning in bearing. That's a great question. How does staph foundation advance assigns a sign? To freezing depth and how to stab Foundation advance assigned to the groundwater table, OK, some of this information. We've already covered. In other presentations and they've been recorded so that's why I didn't go into all this in depth, but If you look at our design parameters here. What you'll notice is that we have the ability to assign? Parameters. In our foundation design so we have the cover and soil parameters. Now, this is where you're going to put in your? If you're geotechnical information for your soil so you'll notice here. I'm using a cohesion less soil. If I'm working with clay. Then I'm going to have a cohesive soil, so, based on the type of soil that you're using? You can choose those values appropriately so here that's where you're going to put in the unit weight of the soil. You're going to put in the depth of soil above the footing. You're going to also put in the depth of the water table, so I think that answers. Two of your questions here, but you can also put in the sheer strength of the. Um of the soil, you can put in a cohesion. Factor if you have a type of clay, so really you're going to need some Geo technical information. Based on the site that your foundation is going to be at and you can put in all this information. And these are the values that are going to be used for the foundation design so I think I. Answer that question for you, I'm here if you have additional questions. Definitely you can ask it again now. Jeremy from Jacobs asked, can the Excel file. Be provided to participants. Yes, I created that file it's just a standard Excel file. So I'll figure out a way that. We can include that. For participants OK. And then we have another question here from Shenandoah with MGA Engineering. How do you get the foundation book OK so that book is? On Bentley Institute Press, so it is available. I want to give everyone my email address, so I'm going to type my email address into the chat window here. And. You can email me directly. And I can. Um. Let me see if I can send to all. I have to select a question here. So the question is. How do we get the book and then I'm going to send? The answer sorry let me try this again, I'm going to type my email address. OK so I'm typing it in now. OK so that's my email address. And I'm going to send to all OK. Now. With that you can send me an email if you need to get that book I can give you specific. Directions on how to get that I don't have all that information available with me right now, but it. Is available on Bentley Institute press so if you wanted to do a search on Google? You could probably pull that information up. And just for everybody. We're talking about the book. Um. That I was sharing earlier so you can see that on my live screen now OK. Any other questions here. Can stab Foundation ignore a certain depth of passive pressure? Save for an example geotechnical report. States to ignore the Top 2 feet of passive pressure now that may be a possibility so that question was. From Germany. Uh at Jacobs there's a possibility that you can if you set the depth of soil above. Your foundation. To the height of the? Um soil that you want to neglect, so whatever depth that you're neglecting you don't use that in the. Depth of your soil so for example, here when I put in the information of depth of soil above the. Footing. I would actually exclude from that value, the depth that I wanted to ignore so that is a way that you could handle that. So it's not exactly. An option to exclude but it's just a way to address that specific. Their specific need OK, so that would be my recommendation there. Um. And I think we answered. On all the questions here, so far, so I'm going to thank everyone. For joining us and let me just go back to the power point here for a second. Um. And will rap it up. From there so. Let me go out one other thing here that we did have a poll question. That we wanted to ask you before we rap it up for this presentation today would you like to be contacted by our sales representative from Bentley Systems? And then I think I just hit submit their so. That poll should you should be able to access that pole. Ann. Either say yes or no. Um if you would like to be contacted by a sales representative from Bentley system for either staad pro or for these stab Foundation advance. Or any other Var Bentley structural products so you can just answer that pull right now OK. And so hopefully, I did that right, I hit submit. And that should be done now. Um. The. Other slide here. I'm still getting familiar with using this version of. The presenter here, so bear with me. Um. OK. So I'm just going to go through this PowerPoint here very quickly and then will rap it up for today. We do have upcoming Stag training that's available, so you can access that through our burnt Bentley learn server. And register for those courses those are live instructor LED. In addition to our sig sessions, which we offer monthly. Also, we've had enhancements for our advanced concrete design solution. Instead, pro so you can get more information on that and I'll see. That inaction. And with that, we were going to wrap it up for today. I want to thank. Everyone for your attendance here and your participation. And we hope to see back in March. So thanks for attending and look forward to seeing you back. In March, thanks again.
