00:00Now, we proceed to Member Incidence Correction.
00:03We do all of this model management because everything is connected to the preceding steps.
00:08Grouping is related to loadings, since we apply loads to sets of members based on function or location.
00:14Renumbering is related to design, because it helps us track member performance clearly in analysis and design results.
00:21In this part, Member Incidences, is related to specifications, because it determines the direction, connectivity, and where to apply those
00:30specifications.
00:31So, we still need to manage and organize it properly so that STAAD can analyze the model correctly, and so
00:38we can get accurate results for this project, which will help us assign the correct sizes and materials for actual
00:44construction use.
00:45Now, we start with the bottom chord.
00:48Select the bottom chord and isolate it to top view.
01:00Then, press Shift-E to show beam incidences.
01:04The rule here for bottom chord is this.
01:06Starting from the king post, the connecting beams around it should be directed away from the king post.
01:12So, from the start of the king post, the incidence should go from green, start node, to blue, end node,
01:19meaning all beams connecting to the king post should be green near the post.
01:23Now, in this part, we see two blue nodes close to the king post, which means we need to change
01:28their incidences.
01:30To do that, use the Select Group tool again.
01:33Highlight the group.
01:34In this case, we know it's part of D1, so select D1 underscore BC.
01:39Now, go to Utilities, then Beam Tools, then Beam Incidences.
01:43In the dialog box that pops up, the rule we follow is this.
01:47Blue, end node, is currently closer to the king post, meaning green start node is farther and closer to the
01:53origin.
01:53But we want the green node near the king post, so the green should be moved away from the origin.
01:58So, instead of using the second option, we select the third option in the list.
02:03Click OK.
02:03Now, the starting node is near the king post, which is what we want.
02:08Now, for D2 underscore BC, we do not use the third option, because the origin is on the upper right
02:14corner in this plan view.
02:16So, we use the second option instead.
02:23Now, all starting nodes are close to the king post, even if the two diagonal bottom chord beams have their
02:29end nodes near the king post.
02:30We still need to check and correct them, so we follow the same process for all trust members.
03:37So again, identify the distance to determine which node is closer to the origin.
03:43Assign the starting node accordingly, ensuring it is also closer to the king post.
03:47In this case, we assign both starting nodes closer to the origin since they are nearest
03:52when the starting node is directed toward the origin.
04:04Thank you very much for joining us today.
04:48Now we move on to the top chord.
04:51Same rule applies.
04:52Starting nodes should be near the king post.
04:55But for this part you'll need to zoom in closely to clearly see the beam incidences.
04:59Use dynamic zoom if needed.
05:32The incorporation in and air.
05:33The wing vendetta.
05:37And it is.
05:37The inner wing, MOS meta.
05:44So the air.
05:50And the back.
05:50And the, the main wing.
05:59And the back.
05:59So the.
09:06So, after this top chord, next is KingPost.
09:10The rule here is simple.
09:12The starting node should be at the bottom.
09:14So, in this case, all KingPost starting nodes are in the bottom, so no need to correct the incidences.
09:29Now, for the web members, same rule as the KingPost, the starting node should be at the bottom.
09:35To fix this, select all the web members and choose the second option in the Redefine Incidence dialog box.
10:06After applying that, you might still see some members with EndNote at the bottom, so we select those specific ones
10:12one by one, or use a drag selection if you wanted.
11:22Now, go to Redefine Incidence again, and this time choose the first option, which is Switch.
11:31Click OK.
11:32Now, all the web members have their starting nodes at the bottom.
11:50Now, let's proceed to the purlins.
11:52Now, let's proceed to the purlins.
12:12The rule here is that starting from this point, going in a clockwise rotation, it should always be green, start
12:19node, followed by blue, end node.
13:00Now, I think so much more about the pass-up battle interrupts.
13:05Now we insist on inch andira-side scan of CT and directorus from the second option by eight-rated march.
13:05Be extra careful here, especially for short-length beams that need to be included.
13:09To fix the incidents, we'll just use the Switch Incidents option.
13:13As you can see, at this point, it starts with blue, which is wrong. It should be green.
13:19So we select that beam or purlin and switch the incidents.
13:23Do the same for the others.
13:25Select and switch until all follow the proper clockwise direction.
13:48I'll see you in the next video.
13:49I'll see you in the next video.
13:51I'll see you in the next video.
14:05Bye.
14:15Bye.
14:45Bye.
15:10And that's it.
15:11We are done with beam incidence management.
15:14That also means we are done with all the model management steps for trusses and purlins.
15:19Now we can proceed to assigning properties.
15:21But before that, again, save the file.
15:25I always remind this to you, especially with detailed work like this, it's important to save often
15:30so we don't lose progress and don't have to redo what we've already done.
15:35what does the equipment have to do today?
15:36You
