Creating the superstructure.
00:07
This adding columns and beams video
00:10
is going to present a workflow for placing steel columns
00:13
and beams in order to model the superstructure of the building.
00:18
During this video, we shall place
00:21
a series of steel columns on grid intersections
00:23
on the ground floor that extend up to the roof.
00:27
Place steel beams between the columns
00:30
and copy the new beams from one level up to another.
00:35
Place beam systems to fill areas of the frame sections
00:38
with a series of roof joists.
00:42
In the ground floor plan, select Column
00:45
from the structural ribbon.
00:47
We shall select the W12 by 40 steel column in the properties
00:52
pallette.
00:53
In the options ball, we should select height and choose
00:57
top of structure roof.
01:00
We can simply place each of the columns
01:02
on the appropriate gridding sections on the ground floor
01:05
level.
01:13
Use the spacebar to rotate the columns as appropriate.
01:47
SIMON JONES: Once done, we shall switch
01:49
to the 3D structural only view.
01:52
And it could be seen that the columns are placed
01:54
on the ground floor level, and they extend up
01:57
to the top of the model.
02:02
Once the columns have been added,
02:04
we can then add the individual beams in between them.
02:10
To do this, we should switch to the top of structure
02:13
second floor level.
02:15
And notice how the view has had unnecessary geometry
02:19
switched off.
02:20
And we are only seeing the columns and slab
02:22
outline with the grid lines that have been set to half tone.
02:28
From the structure ribbon, select Beam,
02:31
and we should choose W18 by 46 shape.
02:37
In the options ball, we should enable the chain option.
02:41
So each new beam will start from the end of the previous beam.
02:46
We also have the tag on placement option enabled
02:49
in the ribbon to automatically annotate
02:51
each new beam as it is added.
02:55
Simply add the beams by snapping to each of the columns.
03:13
SIMON JONES: Once the beams have been added,
03:16
we will change to a fine detail level
03:19
to see the full extent of each steel member,
03:23
and can see how the beams are cut back where they intersect
03:26
with the columns.
03:28
Switching to the 3D structural only view,
03:32
we can see the beams positioned in the 3D view.
03:37
To copy this beam from the second floor to the roof,
03:41
select one of the beams, right click,
03:45
and select All Instances.
03:47
Then select an entire model in order to select all the beans.
03:54
Then from the modify structural framing ribbon, select Copy
03:58
to Clipboard, or simply type Control C.
04:03
Then from the pace menu you select a line
04:07
to selected levels.
04:11
In the select levels dialogue, choose top of strucutre roof
04:15
and OK the dialogue to perform the copy paste.
04:23
The new beams are copied up to the roof level.
04:28
To change the size of an individual beam,
04:30
simply select and change the size
04:33
by selecting New Shape in the properties pallet.
04:36
In this case, the beam has been increased in depth to W24
04:41
by 84, but remains aligned with the top of steel second floor
04:45
level as this insertion point is justified to the top
04:50
of the beam.
04:52
Revit can ultimately place an array of beams
04:55
using the beam systems functionality.
04:60
In this case, we shall use the beep systems to add
05:02
roof choice between two beams.
05:06
Switching to the top of structure view,
05:09
we notice that new beams have not been annotated.
05:12
So it's a copy paste procedure, did not include the tags.
05:17
To rectify this, select Tag All from the annotate ribbon.
05:24
In the tag all not tag dialogue, check the structural framing
05:28
tags option and OK the dialogue, and all the untagged beams
05:33
in the current view will then be annotated
05:36
with the current structural framing tag.
05:40
To create the roof choice, select Beam System
05:44
from the structure ribbon.
05:47
Specify the beam type in the properties pallet.
05:52
We are electing to have a fixed number of beams that will be
05:55
evenly spaced across the span.
05:59
Hovering over one of the beams, making up the framing section,
06:04
preview the layout of the beam system.
06:07
Picking the beam will place the beam system.
06:34
SIMON JONES: At any time, update the number of beams
06:36
and the beams' height to ply to a different framing section.
06:40
In this example, we will select a horizontal beam
06:43
and place six beams.
06:47
Notice how the beam system has been assigned
06:49
a single annotation tag that displays
06:51
the beam type, the number of beams, and their spacing.
06:56
Switching to a 3D view, the beam systems
07:00
can be seen in position.
