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.
