WEBVTT 1 00:00:00.011 --> 00:00:02.064 Hello everyone. 2 00:00:02.297 --> 00:00:04.569 Welcome to Cimbra. I'm Sandy Curth, 3 00:00:05.272 --> 00:00:07.597 one of the co-founders of Forma Systems, 4 00:00:07.598 --> 00:00:11.819 the company that has developed the Cimbra Structural Optimization Tool. 5 00:00:12.490 --> 00:00:15.774 This will just be a brief walkthrough of its functionality and how to get 6 00:00:15.775 --> 00:00:18.771 started. So, when you log in, 7 00:00:18.802 --> 00:00:21.185 you'll see this page, ah, 8 00:00:21.186 --> 00:00:24.192 where you can set up a new project, and you can access it as 9 00:00:24.193 --> 00:00:26.298 your Material and Mold Library. 10 00:00:26.948 --> 00:00:30.280 So, if you're new to the tool, and you want to get set up 11 00:00:30.281 --> 00:00:34.811 with the specifications that make the most sense for your precast plant and 12 00:00:34.812 --> 00:00:39.327 your manufacturers, then start by heading over to the Mold and Material Library. 13 00:00:41.299 --> 00:00:45.852 So, in here, you can see that there's a variety of inputs to 14 00:00:45.853 --> 00:00:50.816 configure the Mold Genie geometry that you have available for a given project. 15 00:00:52.530 --> 00:00:55.824 So, you can adjust things like the stem width, 16 00:00:55.825 --> 00:01:00.841 the number of stems, you know, maybe you're just doing 17 00:01:00.842 --> 00:01:02.998 a single T, 18 00:01:02.999 --> 00:01:05.900 or maybe your focus is more on the double T. 19 00:01:07.208 --> 00:01:12.301 You can adjust the depth, Peace. And 20 00:01:12.302 --> 00:01:14.966 all of this can be done in Metric or Imperial, so depending on where 21 00:01:14.967 --> 00:01:17.341 you're working, maybe this will make a little more sense. 22 00:01:20.087 --> 00:01:24.653 You know, you can adjust the different standard ratios for 23 00:01:24.654 --> 00:01:29.506 your design. And so once you've configured a mold, 24 00:01:29.842 --> 00:01:33.454 then you can save that mold to your library. 25 00:01:33.455 --> 00:01:35.629 First, you have to give it a name, so we'll call this, 26 00:01:35.630 --> 00:01:38.222 CustomMold1. 27 00:01:38.223 --> 00:01:41.125 We'll save it to our library, and then you can see here we have 28 00:01:41.126 --> 00:01:43.759 this library of molds, so some of these are, 29 00:01:43.770 --> 00:01:47.885 standard designs you might find in the PCI Precast Handbook, 30 00:01:47.896 --> 00:01:51.833 or other designs that we've just come up with as we're experimenting. 31 00:01:51.834 --> 00:01:53.842 So, 32 00:01:53.843 --> 00:01:56.183 that's basically the mold library. 33 00:01:56.519 --> 00:01:59.258 Then you're going to want to go to the material library, 34 00:01:59.681 --> 00:02:04.225 where you'll see we already have pre-populated a relatively wide variety 35 00:02:04.226 --> 00:02:07.397 of concrete mixes, and, rebar as well as, 36 00:02:07.407 --> 00:02:09.636 strand type. So, 37 00:02:09.637 --> 00:02:11.960 again, here, if you would like, you can, 38 00:02:11.971 --> 00:02:14.441 you can configure and add your own materials. So, 39 00:02:14.747 --> 00:02:17.184 once you have some molds and materials, then it makes sense for you, 40 00:02:17.963 --> 00:02:20.137 you can begin a new project. 41 00:02:20.426 --> 00:02:23.123 And just to save us a little time, I'll just open an existing one. 42 00:02:24.489 --> 00:02:28.966 So, here, you can see a project where I have a couple different, 43 00:02:28.977 --> 00:02:33.583 span and load conditions. And I've started by setting 44 00:02:34.213 --> 00:02:36.403 my first objective as carbon. 45 00:02:36.404 --> 00:02:39.213 So, the goal with this particular optimization will be to find the, 46 00:02:39.224 --> 00:02:42.103 the system or the, 47 00:02:42.104 --> 00:02:45.227 the set of systems that make the most sense for this project in terms 48 00:02:45.228 --> 00:02:49.557 of minimizing the amount of carbon that's going into the products produced. 49 00:02:51.004 --> 00:02:54.106 You can see the governing code is ACI 318. 50 00:02:54.107 --> 00:02:56.187 As Simberg grows, we'll support more codes. 51 00:02:56.197 --> 00:03:00.142 there's a clear cover requirement here that you can add in your deflection limit. 52 00:03:00.153 --> 00:03:02.903 if you'd like to see it, if it's possible to make the design without 53 00:03:02.904 --> 00:03:05.878 needing any passive rebar, you can toggle that here as well. 54 00:03:05.889 --> 00:03:09.557 so you can see that I've selected a little variety of molds. 55 00:03:09.568 --> 00:03:11.572 you know, some, some standard, 56 00:03:11.583 --> 00:03:14.115 options like a DT24, DT26. 57 00:03:14.238 --> 00:03:17.298 and then what we've done here is once you've configured the all of your 58 00:03:17.299 --> 00:03:19.485 selections, you can push generate designs. 59 00:03:20.516 --> 00:03:23.412 And what that'll do is it'll produce a design matrix. 60 00:03:23.413 --> 00:03:25.806 So here, when we ran this optimization, 61 00:03:25.817 --> 00:03:28.824 we evaluated a little bit over 400,000 designs, 62 00:03:28.834 --> 00:03:33.398 found 12 that were feasible and well within the parameters of manufacturability 63 00:03:33.399 --> 00:03:38.100 as defined by your mold geometry. And what you can do here now is 64 00:03:38.101 --> 00:03:42.844 you can across the different mold options and different design options and 65 00:03:42.845 --> 00:03:45.270 see what offers the greatest advantage. 66 00:03:45.271 --> 00:03:48.405 So, if we select one of these designs, 67 00:03:49.535 --> 00:03:54.119 and then scroll down, you can see all of your typical structural validation 68 00:03:54.120 --> 00:03:58.677 information, and you can also run back the optimization itself, 69 00:03:58.678 --> 00:04:03.576 which can be kind of interesting. So you can see Thank this comparison 70 00:04:03.577 --> 00:04:07.043 across the different free variables, so the number of strands, 71 00:04:07.285 --> 00:04:09.432 their position, that type of thing. 72 00:04:12.552 --> 00:04:16.899 And then you'll see the, the finalized design for that, 73 00:04:16.910 --> 00:04:21.597 particular option that you selected, as well as a collection of the 74 00:04:21.598 --> 00:04:24.129 typical structural checks you'd expect, 75 00:04:24.140 --> 00:04:29.354 you know, bending moment, you 76 00:04:29.355 --> 00:04:31.374 can look at the the, 77 00:04:31.375 --> 00:04:34.146 typical checks you would find in, you know, 78 00:04:34.147 --> 00:04:37.510 a standard structural validation software for precast design. 79 00:04:38.310 --> 00:04:41.892 You can also download a report or download a spreadsheet, 80 00:04:41.893 --> 00:04:44.845 an Excel sheet. That has all of this data in it so you can 81 00:04:44.846 --> 00:04:48.256 quickly compare, or pass along the data to someone else on your team for 82 00:04:48.257 --> 00:04:50.627 bidding, that sort of thing. So, 83 00:04:50.800 --> 00:04:53.170 that's the general overview of the tool, 84 00:04:53.181 --> 00:04:56.203 please give it a try, let us know what you think, and thank you 85 00:04:56.204 --> 00:04:56.560 so much.
