WEBVTT 00:00.000 --> 00:08.640 Alright, everyone, so moving into the next set of plans here in our structural set, we're 00:08.640 --> 00:14.520 going to go to our S1-7H roof framing plan. 00:14.520 --> 00:20.560 So this is going to be the next level up from a structural standpoint. 00:20.560 --> 00:28.640 This is also going to encompass all of the areas that did not have any structure below. 00:28.640 --> 00:34.240 So some of those open to above areas, like in this bottom right corner here, where we 00:34.240 --> 00:39.120 can see this large rectangle that has these lines going through the middle. 00:39.120 --> 00:44.600 That was totally open on the floor below and we can see that the structure for it is built 00:44.600 --> 00:47.280 at this level, at our roof level. 00:47.280 --> 00:53.480 So we're going to dive into that, get structural makeup and any of the beams or joists that 00:53.480 --> 00:55.360 make that up. 00:55.360 --> 01:01.720 We are going to take a deep dive into this plan to just understand any potential differences 01:01.720 --> 01:07.560 that we see with the structural members, with any of the connections. 01:07.560 --> 01:11.440 We're of course going to dive into the notes here to really understand the implications 01:11.440 --> 01:13.440 of those notes. 01:13.440 --> 01:19.320 After we finish this plan, we are going to deep dive walk through in a lot of our typical 01:19.320 --> 01:21.480 details and sections. 01:21.480 --> 01:26.280 In those, we're really going to talk about some of the connection points here. 01:26.280 --> 01:31.960 So some of the bolted or welded connections between all of these different steel members 01:31.960 --> 01:37.440 and how they tie back to the outside perimeter concrete wall and the rest of the structure 01:37.440 --> 01:38.440 here. 01:38.440 --> 01:43.360 And that's really going to give us a very strong and holistic understanding of how to read 01:43.360 --> 01:47.200 and interpret every portion of these plans. 01:47.200 --> 01:51.400 So for right now, let's go ahead and focus on this one here. 01:51.400 --> 01:54.560 And what we're going to do, we're going to start in the bottom left corner and kind of 01:54.560 --> 01:57.440 work our way out here. 01:57.440 --> 02:03.960 So continuing to see that we have some very similar members on this page, then we did 02:03.960 --> 02:05.720 on the previous one. 02:05.720 --> 02:10.080 So we can see we've got our K series joists. 02:10.080 --> 02:14.600 We can see we've got some W series beams over here. 02:14.600 --> 02:20.400 We can see left, right, we've got those 14 by 22s up and down. 02:20.400 --> 02:23.480 We got these W 16 by 31s. 02:23.480 --> 02:28.040 We can see that we learned in the last lesson how we have this arrow telling us that these 02:28.040 --> 02:32.040 beams are sloping a certain direction. 02:32.040 --> 02:36.960 And you can actually tell how much they slope over that amount of time too, because you 02:36.960 --> 02:44.360 can even see where I'm highlighting here, over on the left hand side, that the top of 02:44.360 --> 02:49.200 beam dimension is going to be 29 11 at a certain grid line. 02:49.200 --> 02:54.000 And then as it slopes over to the next grid line, we can see that the top of beam over 02:54.000 --> 02:58.120 here is actually going to be 29 eight. 02:58.120 --> 03:05.880 So that tells us that over this particular run of dimension, so this 11 foot run of dimension, 03:05.880 --> 03:12.360 that there is going to be a three inch differential between what is on the column line h side and 03:12.360 --> 03:15.160 what is on the column line g a side. 03:15.160 --> 03:22.080 So that is really clear that it's laid out for us of how much these beams have to slope 03:22.080 --> 03:26.400 over this 11 foot bay opening that we can see. 03:26.400 --> 03:28.760 So really helpful information. 03:28.760 --> 03:33.040 That's just how we interpret those notes and those dimensions. 03:33.040 --> 03:38.920 And really easy for us to determine exactly how these need to be installed based on these 03:38.920 --> 03:41.760 notes. 03:41.760 --> 03:48.480 So continuing to go up this left side, we can see we've just got a section cut through 03:48.480 --> 03:49.480 here. 03:49.480 --> 03:53.160 That's going to give us a few of what this whole wall should look like. 03:53.160 --> 03:57.640 Let's go ahead and take a look into that one and see what sort of insight that gives 03:57.640 --> 03:58.640 us. 03:58.640 --> 04:00.640 That is detailed. 04:00.640 --> 04:06.880 So in this particular area, we have a pretty different setup than we had on the perimeter 04:06.880 --> 04:09.080 of the floor below. 04:09.080 --> 04:15.200 So instead of there being that kind of insulated concrete form wall that the structure ties 04:15.200 --> 04:22.000 into here, we've got some curtain wall that this is all built on top of. 04:22.000 --> 04:27.080 So we can see here we've got the curtain wall down at the bottom here, which is going 04:27.080 --> 04:31.120 to be this kind of window that is drawn out. 04:31.120 --> 04:35.920 And we can see that we've got a connector from that curtain wall back to the structure. 04:35.920 --> 04:38.200 That is all going to be highlighted in the notes here. 04:38.200 --> 04:43.880 This one is saying that it's a lateral connection by the curtain wall supplier. 04:43.880 --> 04:47.680 And what we were just looking at was going to be our beams. 04:47.680 --> 04:53.720 So the cut through is facing if we're looking at the page, it's facing up. 04:53.720 --> 04:58.600 So if we're looking straight through that cut, we can see this perimeter beam that we've 04:58.600 --> 05:02.520 got here, this I beam that I just drew out in the highlighter. 05:02.520 --> 05:08.000 And then every so often as there are beams coming into it, that's what we'll see in this 05:08.000 --> 05:12.760 left to right drawn out beam within this detail as well. 05:12.760 --> 05:20.320 So in this detail, what is graphically shown here is that we've got the structural beams. 05:20.320 --> 05:26.040 We've got some angle attached to those beams on top of that angle. 05:26.040 --> 05:30.000 We have what looks to be cold formed metal framing. 05:30.000 --> 05:36.920 So as we come out of that angle, we've got this vertical cold formed metal framing assembly 05:36.920 --> 05:37.920 here. 05:37.920 --> 05:43.280 So we've got framing up and then we've got some framing over to the left in the way we 05:43.280 --> 05:48.720 can tell that this is cold formed metal framing is from these call outs here. 05:48.720 --> 05:54.840 So these call outs that I'm highlighting are going to be the type of stud and the spacing 05:54.840 --> 05:56.240 of the stud. 05:56.240 --> 06:01.440 This is going to be kind of heavy gauge cold formed metal framing here. 06:01.440 --> 06:06.400 That is what those call outs are going to represent. 06:06.400 --> 06:12.760 And just to break down what some of those numbers mean, so that 600 that is going to be the 06:12.760 --> 06:19.440 stud depth in hundreds of an inch, so that is going to be a six inch deep stud. 06:19.440 --> 06:26.200 The S is going to designate that is a stud and it's not any sort of track or a different 06:26.200 --> 06:31.200 size or shape of steel component. 06:31.200 --> 06:38.600 The 68 is going to designate the material thickness in mills and that is going to be equivalent 06:38.600 --> 06:42.800 to a 16 gauge heavy gauge structural stud. 06:42.800 --> 06:47.680 And that 16 inches is going to mean that it is on center. 06:47.680 --> 06:52.680 So 16 inches on center every 16 inches is where one of those needs to be placed. 06:52.680 --> 06:58.280 Again, of course, this is not anything that needs to be memorized, but it is helpful 06:58.280 --> 07:03.600 to once you see that sort of number and letter designation to at least have an idea 07:03.600 --> 07:09.640 that that represents, hey, that is cold formed metal framing, that is not a rolled steel 07:09.640 --> 07:15.920 member, that is not steel decade or that is not, you know, wood framing, it is clear 07:15.920 --> 07:21.120 to understand that those particular numbers represent cold formed metal framing. 07:21.120 --> 07:26.040 So it is super helpful to understand that. 07:26.040 --> 07:31.800 And what we also see within this detail, I am going to go ahead and delete all of these 07:31.880 --> 07:37.480 highlighters because there's a handful of them, but let's get these out of the way so 07:37.480 --> 07:41.160 that we can look at the rest of the detail here. 07:41.160 --> 07:46.800 And let me go ahead and just grab the last tool and do that, get these out of the way 07:46.800 --> 07:48.760 here. 07:48.760 --> 07:55.320 What we can also see on these structural plans is a lot of different weld symbols here. 07:55.320 --> 08:01.240 So the way that most structural things are put together, there's really only going to 08:01.240 --> 08:04.640 be a couple of methods of attachment. 08:04.640 --> 08:09.440 So there's going to be bolted connections, which of course we can see an example of one 08:09.440 --> 08:12.040 of those in this detail here. 08:12.040 --> 08:16.200 We can see where beams are running into each other. 08:16.200 --> 08:21.440 There is going to be holes left open on those beams and there is going to be bolts that 08:21.440 --> 08:25.400 are going to fasten those two pieces together. 08:25.400 --> 08:30.520 When we have a bolted connection, we're just going to see the description of it down below, 08:30.520 --> 08:32.200 which I've just highlighted. 08:32.200 --> 08:36.880 And what that's going to do is it's just going to tell us the size of the bolts and the 08:36.880 --> 08:39.320 type of bolts that are going in there. 08:39.320 --> 08:43.920 So here we can see that we've got four, three quarter inch diameter bolts. 08:43.920 --> 08:50.840 So that is going to dictate the specifics of the sizing around that particular connection 08:50.840 --> 08:54.480 point at a bolted connection. 08:54.480 --> 08:58.120 We may typically also have a stiffener at each of the beams as well. 08:58.120 --> 09:00.800 So that's something that's going to be called out here. 09:00.800 --> 09:06.720 But in addition to bolted connections, we are also oftentimes going to have welded connections 09:06.720 --> 09:07.880 as well. 09:07.880 --> 09:12.960 So when we're looking at a detail like this, and we see something like I'm highlighting 09:12.960 --> 09:20.320 on the screen right now, so one of these flags with one of these triangular notes on it, 09:20.320 --> 09:24.840 that is going to dictate that there is a weld at this location. 09:24.840 --> 09:29.880 And what that symbol means is it means a particular type of weld. 09:29.880 --> 09:35.200 So going to some of the other weld marks on the plan here, if we go to the top of this 09:35.200 --> 09:38.520 angle, we can see we've got another flag. 09:38.520 --> 09:44.280 And then as we go over, we just have a triangle on the bottom of this line here. 09:44.280 --> 09:49.200 And we have these two lines that shoot out in different directions on the end of it. 09:49.200 --> 09:53.400 We can also see that this is called out for each stud as well. 09:53.400 --> 09:59.160 So these lines are not, they may be slightly cryptic, but they do have meaning to them 09:59.160 --> 10:06.320 and all of the triangles and locations of lines on them are very telling of the specifics 10:06.320 --> 10:09.680 of what needs to be welded in place here. 10:09.680 --> 10:15.720 So again, you can see there's a couple of other ones as we look down to just to the left 10:15.720 --> 10:16.720 of our bolted connection. 10:16.720 --> 10:22.440 We can see we've got two different types of welds that are showing up here as well. 10:22.440 --> 10:26.360 Because of these are called out to be a three sixteenths inch weld. 10:26.360 --> 10:30.680 The top one here just has a triangle on the bottom of it, the bottom one has a triangle 10:30.680 --> 10:34.640 on both the top and the bottom sides of it. 10:34.640 --> 10:43.280 So what all of these mean is that these are fillet welds and that is a type of weld. 10:43.280 --> 10:50.760 The position of these triangles has to do with where that weld needs to be located. 10:50.760 --> 10:57.000 The dimension shown has to do with the size of the weld itself. 10:57.000 --> 11:02.960 So the leg size of the weld is what those call out dimensions are for and that's what those 11:02.960 --> 11:04.800 are dictated. 11:04.800 --> 11:11.600 So we don't need to get too too far in depth here unless we are actually a welder or 11:11.600 --> 11:18.480 we are a structural steel fabricator, but that is what these symbols mean. 11:18.520 --> 11:24.160 There is going to be a symbols page as well with this particular plan set. 11:24.160 --> 11:29.840 There is not a symbols and abbreviations page in the beginning, but just for the understanding 11:29.840 --> 11:34.880 of everybody on this in this course, this is what these mean. 11:34.880 --> 11:36.440 These are weld symbols. 11:36.440 --> 11:43.440 They symbolize different types of welds with different sizes and dimensions to them on 11:43.480 --> 11:50.800 different faces or locations of the angle or the pieces that are being welded together. 11:50.800 --> 11:58.760 So just some helpful context to help make sense of what can be a complicated detail there. 11:58.760 --> 12:04.560 The other thing to note with this detail as well is we see that we've got some dimension 12:04.560 --> 12:06.400 callouts as well. 12:06.400 --> 12:11.840 So these are things that we've seen elsewhere in our plans, but anytime we see this 12:11.840 --> 12:18.480 circular marker here, which looks like maybe a crosshair with some of these regions filled 12:18.480 --> 12:24.760 out with color, that's kind of indicating to us a certain benchmark or saying that a 12:24.760 --> 12:27.840 certain height needs to be achieved at a certain area. 12:27.840 --> 12:33.600 So we can see that the top of this assembly's got to be at 32 feet, 11 inches from our 12:33.600 --> 12:35.520 data zero, zero. 12:35.520 --> 12:41.280 So again, just telling us some context of where this needs to be located, where it sits 12:41.360 --> 12:46.160 in space and the dimensions that we need to keep in mind when we are actually building 12:46.160 --> 12:48.480 this out in the field. 12:48.480 --> 12:53.920 So that's a really good understanding of one of these complicated details here. 12:53.920 --> 13:14.440 Now let's go back to our framing plan and go through the rest of this. 13:14.440 --> 13:18.720 So we looked at this kind of G cut through section over here. 13:18.720 --> 13:22.560 That gives us a really strong understanding of what this whole side of the building looks 13:22.560 --> 13:24.320 like. 13:24.320 --> 13:27.080 Now let's go ahead and look through this plan. 13:27.080 --> 13:32.960 And as we're moving over to the right a little bit here, we can see that we have a different 13:32.960 --> 13:38.720 structural member that we have not come across yet in our previous set of plans. 13:38.720 --> 13:45.000 So what we've got here is this 32 L H 10 SP one. 13:45.000 --> 13:50.920 So maybe thinking this is a member that we have not seen yet at this point. 13:50.920 --> 13:57.120 So what these are, these are going to be joists as well. 13:57.120 --> 14:04.540 So similar to the K series and KCS series joists that we have looked at on previous 14:04.540 --> 14:10.840 plans, this L H series is also going to be a joist. 14:10.840 --> 14:16.040 And it's going to be a joist that is able to support a longer span. 14:16.040 --> 14:23.120 So if we break down what this designation means, the 32 is going to be the depth of 14:23.120 --> 14:24.280 the joists. 14:24.280 --> 14:30.280 So again, that's going to be the dimension from the top cord to the bottom cord. 14:30.280 --> 14:35.120 The L H is going to mean a long span joist. 14:35.120 --> 14:40.640 This is used for longer spans than our typical K series joists that we've seen elsewhere 14:40.640 --> 14:42.320 on the project. 14:42.400 --> 14:47.360 These are going to be really common in kind of commercial buildings, buildings with large 14:47.360 --> 14:50.320 open floor plans. 14:50.320 --> 14:54.920 That 10 is going to indicate just the number of the joists. 14:54.920 --> 15:03.320 So within a given series of the standard joist sizes and types in the L H long span series, 15:03.320 --> 15:06.280 this one happens to be number 10. 15:06.280 --> 15:11.880 And what that really indicates is the load carrying capacity of this particular type of 15:11.880 --> 15:14.120 joist. 15:14.120 --> 15:19.360 And that SP one may often mean a special profile. 15:19.360 --> 15:24.880 So maybe there is a certain geometry that is different from the standard, but that is 15:24.880 --> 15:31.120 what that additional characterization of SP one is going to reflect. 15:31.120 --> 15:35.720 So that's what that sort of joist is going to be. 15:35.720 --> 15:41.120 If we had a symbols and abbreviations page within this structural set, that of course 15:41.120 --> 15:46.840 would be called out on that page, and it would be very clear to see, however, that does 15:46.840 --> 15:48.680 not exist for this plan set. 15:48.680 --> 15:54.320 So that is what we're doing now is just kind of walking through what all of these mean 15:54.320 --> 15:59.280 and how we can go about understanding what they're going to look like in the field, what 15:59.280 --> 16:03.120 we need to order to make sure we have the right materials. 16:03.120 --> 16:08.240 So that is going to be what that particular designation means. 16:08.240 --> 16:16.520 As we go down, we can see that there is a specific naming convention and a specific height 16:16.520 --> 16:18.840 called out that these have to be at. 16:18.840 --> 16:25.280 So at this ridge, the top of steel is to be at 30 feet, three and a half inches. 16:25.280 --> 16:31.680 So again, we know exactly where the top of these is to end up here. 16:31.680 --> 16:38.200 If we look over into the bottom right corner into this large open span area, we've identified 16:38.360 --> 16:40.760 this to be our gymnasium. 16:40.760 --> 16:47.080 So this was the area that was totally open from below on the previous plan below us because 16:47.080 --> 16:51.440 it is kind of a two story large open span in here. 16:51.440 --> 16:56.640 And we can see that we have some different joist types in here as well. 16:56.640 --> 17:05.840 So if we look at these particular joists, we can see that these are 40 LH12, SP4 and 17:05.840 --> 17:08.800 SP3 type joists. 17:08.800 --> 17:16.000 So 40, of course, is going to be the depth of this joist LH, again, is going to be that 17:16.000 --> 17:23.520 long span designation 12 is going to be the number in the series of standard joist types. 17:23.520 --> 17:28.040 And then we can see that we've got SP4 and SP3 here. 17:28.040 --> 17:31.120 Those are going to mean special profile as we mentioned. 17:31.640 --> 17:37.120 It makes sense to have these different kinds of profiles in this gymnasium area. 17:37.120 --> 17:42.240 If you're familiar with maybe your high school gymnasium, you know that there's oftentimes 17:42.240 --> 17:49.080 typically HVAC equipment like ductwork that is running through the ceiling of some of 17:49.080 --> 17:49.920 these. 17:49.920 --> 17:55.280 So it would make sense that the joists have certain profiles and certain openings inside 17:55.280 --> 18:02.600 of them to allow that HVAC equipment to run through the joists and continue on through 18:02.600 --> 18:07.840 the building to still make sure that everything is being supported properly from a structural 18:07.840 --> 18:15.240 standpoint, but to also ensure that the proper MEP of the building is able to be run through 18:15.240 --> 18:21.000 and around those joist systems as needed to connect to the rest of the building. 18:21.000 --> 18:26.040 And we can also note here that this particular area says to see note 18. 18:26.040 --> 18:29.720 So let's just go ahead and do that while we can. 18:29.720 --> 18:33.600 And okay, it looks like note 18 is not on this plan. 18:33.600 --> 18:42.440 So if we go into our general notes here, maybe there's a note 18 in the general notes. 18:42.440 --> 18:48.280 And it looks like we've got a note 17. 18:48.920 --> 18:52.200 You know, I'm not seeing a note 18 right here. 18:52.200 --> 18:56.840 So maybe we can disregard that maybe that is meant to be something back on this plan that's 18:56.840 --> 19:02.800 not existing somewhere in the plan notes, but nevertheless, whatever we see a note there, 19:02.800 --> 19:06.240 it's always something we have to dive into and see if we can follow up on. 19:06.240 --> 19:10.760 So that's going to be the different joist types here. 19:10.760 --> 19:15.680 If we want to take a look at the perimeter bearing details, we can do that just to see 19:15.800 --> 19:20.640 if these are similar or different than the ones that we looked at on the previous page. 19:20.640 --> 19:25.840 So we can see we've got K, which is going to be kind of the detail where there is a 19:25.840 --> 19:26.840 lentil. 19:26.840 --> 19:30.960 And then we've got D, which is going to be the detail where there is not any sort of opening 19:30.960 --> 19:35.000 and where there's just kind of continuous exterior wall. 19:35.000 --> 19:42.040 So let's go ahead into our 5.2 page here and we can look at D first. 19:42.040 --> 19:47.080 So D looks to be a pretty standard detail, just that kind of bearing plate that the joist 19:47.080 --> 19:52.480 is going to be bearing on and then angle and metal decking on top of that. 19:52.480 --> 19:53.480 That makes sense. 19:53.480 --> 19:56.240 That's kind of what we have what they expect there. 19:56.240 --> 20:02.480 But if we go back to one of the other details where we are at an opening, I think maybe 20:02.480 --> 20:08.360 K was the title of it, let me go back and double check on the framing plan. 20:08.360 --> 20:11.680 Yeah, K. 20:11.680 --> 20:18.920 So when we get to K, we can see very similar treatment at the joist itself, bearing plate 20:18.920 --> 20:21.880 set in the wall that the joist bears on. 20:21.880 --> 20:27.400 This particular one just happens to be where there is an opening below. 20:27.400 --> 20:34.000 So we can just see that the wall header itself of the insulated concrete form wall has this 20:34.000 --> 20:36.280 additional rebar in it. 20:36.280 --> 20:40.120 And we can also see that it has that lentil that we talked about. 20:40.120 --> 20:47.880 So when that wall is poured, we can see that we have a bearing plate or an embedded piece 20:47.880 --> 20:52.880 of metal here that we're going to stick in this concrete wall as we pour it, as it forms 20:52.880 --> 21:00.760 up in solidifies, it will give us a flat metal surface so that we can weld this angle, 21:00.760 --> 21:06.440 this lentil on to that bearing surface and then we can build our exterior masonry on 21:06.440 --> 21:10.320 top of that lentil and sit down on it. 21:10.320 --> 21:15.640 So really, really easy to just go ahead and follow through those different details so that 21:15.640 --> 21:23.520 we can understand the construction of the adjacent construction at all of these different areas. 21:23.520 --> 21:27.640 Go ahead and jump back into this roof framing plan right now. 21:27.640 --> 21:31.320 So we've looked at some different structural members. 21:31.320 --> 21:37.400 We have looked at different details at the parameters of building. 21:37.400 --> 21:41.560 Let's just go ahead and see if there is anything else in this plan. 21:41.560 --> 21:47.360 One of the things that we see is we see these graphical openings that are shown here. 21:47.360 --> 21:52.720 And since we don't see any detail called out on the plans, my assumption is that it is 21:52.720 --> 21:56.720 going to be noted within the general notes here. 21:56.720 --> 21:59.960 And these are ones that we've seen on previous plans too. 21:59.960 --> 22:08.440 But we can see that the four and five are saying to provide this size angle frame all around 22:08.440 --> 22:11.280 all roof openings larger than a certain size. 22:11.280 --> 22:18.000 So this is asking for a four by three by five sixteenths angle frame all around the roof 22:18.000 --> 22:25.080 openings that are larger than one foot by one foot and coordinate the locations and sizes 22:25.080 --> 22:27.640 with the architectural and mechanical drawings. 22:27.640 --> 22:32.360 So the structural drawings are telling us that there are openings in this area so that 22:32.360 --> 22:38.440 we have to provide the proper structure around those openings. 22:38.440 --> 22:43.080 But this note is also telling us that the architectural and the mechanical drawings are going 22:43.080 --> 22:48.440 to have the specific sizes of the openings as well as the locations of them off of column 22:48.440 --> 22:51.880 lines within building. 22:51.880 --> 22:55.960 And what we can also do is look at this detail so we can get a better understanding here. 22:55.960 --> 23:02.520 So this is calling us out to look at a detail C on S3-5. 23:02.520 --> 23:07.160 So let's just go ahead and do that here and when we look at this detail C, that's giving 23:07.160 --> 23:12.840 us a plan view as well as a section view of what these openings should look like. 23:12.840 --> 23:18.560 So in the plan view, we can see that this is how the openings are to be installed. 23:18.560 --> 23:26.080 So we'll have our two roof beams or roof joists running parallel to each other. 23:26.080 --> 23:31.240 Perpendicular to those, we will have this angle frame that we referenced. 23:31.240 --> 23:37.680 So we can see we've got the angle frame coming down here and then to be continuous and go 23:37.680 --> 23:42.640 all the way around all the sides, we'll be putting our angles on these sides of the opening 23:42.640 --> 23:43.960 as well. 23:43.960 --> 23:51.160 So this detail is going to show us graphically how we need to provide support around these 23:51.160 --> 23:53.320 different openings in the section. 23:53.320 --> 23:57.120 Of course, it's going to show us a cut through of what it looks like. 23:57.120 --> 24:00.280 So we can see we've got our beams on the side. 24:00.280 --> 24:08.120 We've got these angles that are going to be sitting on top of these beams here and again, 24:08.120 --> 24:12.200 we can see right around the opening, we've got these angles going in the other direction. 24:12.200 --> 24:17.400 So this is just a really helpful section and plan view to help us understand what this 24:17.400 --> 24:19.240 is going to look like. 24:19.240 --> 24:24.960 In addition to those one by one or larger than one by one openings, we can also see that 24:24.960 --> 24:30.440 note number two down at the bottom here calls out to provide the angle frame at all roof 24:30.440 --> 24:32.240 drains as well. 24:32.240 --> 24:37.960 So even if it's not specifically called out on the plans to go around those roof drains, 24:37.960 --> 24:44.480 we know that this detail number two is telling us that it needs to go there as well. 24:44.480 --> 24:49.840 So back into our roof framing plan, we have looked at a lot of different structural members. 24:49.840 --> 24:53.920 We talked about some of these different openings here. 24:53.920 --> 25:00.600 So let's just go ahead and do a scan of the rest of this plan to see if we see anything 25:00.600 --> 25:02.920 different here. 25:02.960 --> 25:05.880 We have the similar joist types. 25:05.880 --> 25:13.480 We have some bearing plates over on the right hand side here as we get up into this section. 25:13.480 --> 25:18.840 We can see that we have our similar wide flange type steel beams. 25:18.840 --> 25:23.720 We've got that sloping designation that are causing all of these to slope inwards to 25:23.720 --> 25:26.560 this central beam. 25:26.560 --> 25:31.560 We've got a couple of different dimensions that are called out here of the top. 25:31.560 --> 25:35.560 No real difference from what we've seen in previous areas. 25:35.560 --> 25:38.480 Oh, here's another one. 25:38.480 --> 25:44.920 So what we're looking at on the screen here in the in front of us is we can see we've got 25:44.920 --> 25:50.840 a channel or a C member called out as well. 25:50.840 --> 25:56.720 So looking in front of us, we can see we've got a couple of different members here. 25:56.720 --> 26:01.800 And what that is going to be is that C designation. 26:01.800 --> 26:08.040 So that is going to mean that these channels are going to be this particular one, this eight 26:08.040 --> 26:09.840 by 11.5. 26:09.840 --> 26:12.360 The eight is going to be the nominal depth. 26:12.360 --> 26:19.480 So it's think of this as like a C shape member with the inside of the C being eight inches. 26:19.480 --> 26:25.520 And the 11.5 is going to be the pounds per foot similar to our wide flange. 26:25.520 --> 26:30.880 So instead of this being an I beam shape, this is going to be a C shape almost like a 26:30.880 --> 26:31.880 channel. 26:31.880 --> 26:36.280 So a flange at the top, the web in the middle and then a flange at the bottom. 26:36.280 --> 26:39.920 So that's what this particular member is going to designate.
