SIMON JONES: Co-authoring a structural model
00:04
in Revit creating the super-structure.
00:08
In this adding building core video,
00:10
we're going to present a workflow
00:12
for structural engineers to select which
00:14
walls and floors that are in the architectural model
00:18
are to be considered part of the structural frame
00:21
and copy them over to the structural model.
00:24
During this video, we shall copy monitor the elevator core
00:28
and floor slabs, cut holes in the floor slabs
00:32
to accommodate the elevator mechanism and services riser
00:36
a shaft, add a slab edge to the ground floor concrete slab
00:41
to thicken its perimeter.
00:44
We are working in the small Medical Center.
00:47
And in this 3D view, we are seeing the architect's model
00:50
that is linked in.
00:52
This consists of structural and non-structural objects,
00:57
which a copy of the objects will be
00:59
needed to build a structural model ready for finite element
01:02
analysis.
01:05
From the Collaborate ribbon, select Copy Monitor,
01:09
then choose Select Link and pick the architectural link.
01:14
From the ribbon, select Options, so we
01:17
may choose which family types to use in the structural model.
01:22
First select the Walls tab.
01:25
And we should map just one wall type that we're interested.
01:27
In this case, we shall a map elevator
01:31
wall 12 inch CMU furring and wood planks
01:34
to simply elevator a wall 12 inch CMU.
01:38
Since the furring and wood planks finish,
01:40
applied to the walls not part of the structural model.
01:46
Next, switch to the Floors tab, map generic 12 inch
01:50
to 5 inch concrete and hardwood floor
01:54
to 4 and 1/2 inch in W concrete on 12-inch metal deck.
02:01
Then select Copy in ribbon and select
02:04
each of the walls that define the elevator shaft
02:10
and then select the two main floors.
02:15
Select Finish to complete the copy monitor process.
02:20
The selected walls and floors have been copied
02:22
into the structural model.
02:24
However, they're positioned in the same place
02:26
as the original architect's object I've linked in,
02:30
so it is not easy to make them out.
02:33
In order to differentiate them, we
02:35
should duplicate the current default 3D view
02:39
and rename it to
02:52
Then use Visibility Graphics Overrides dialogue
02:56
to hide the architectural and MEP links in the view
03:00
so that we only see the geometry in the structural model.
03:07
In order to be included in the analysis model,
03:10
new floors and walls need to be flagged as structural.
03:14
First, we select all the new geometry
03:16
and fill throughout just the walls
03:19
and enable structural in the Properties palette.
03:23
Next, we shall select the two floors
03:26
and also enable their structural property.
03:32
Switching to the analytical model view,
03:34
it could be seen that these objects have
03:37
an analytical representation.
03:44
Whilst we have the overall size of the floor slabs
03:47
from the architect, there are a couple
03:49
of significant openings need to be
03:51
made in the floors that will impact the structural analysis
03:54
calculations.
03:56
Therefore, it is necessary to cut some holes
03:58
in the new slabs.
04:01
The first hole we should cut is in the ground floor slab
04:04
underneath the elevator shaft in order
04:06
to accommodate the elevator plate.
04:09
In this case, we shall select the slab in 3D,
04:13
and then choose Edit Boundary from the Modify Floors ribbon.
04:19
Switching to the ground floor view,
04:21
we can view the slab boundary in context
04:23
with the architectural floor plan
04:27
And we can zoom into an area of the elevator shaft.
04:32
Simply trace around the edges of the elevator shaft
04:59
and cut out the redundant edge from the original boundary.
05:09
Notice the coordination monitor alert
05:11
that has highlighted that the sketch is
05:13
different from the version provided by the architect.
05:17
To remain coordinated with the architect,
05:19
take a note to have a review of the change
05:22
in order to maintain consistency between the two models.
05:28
Switching to the 3D structural only view,
05:31
the new opening can be clearly seen under the elevator
05:34
shaft in the ground floor slab.
05:42
We may also want to check for major openings required
05:44
for routing of the MEP services.
05:48
Using Visibility Graphics Overrides,
05:50
temporarily switch to MEP model back on again
05:54
in the 3D structural only view or alternatively create
05:58
another view dedicated to just structural and MEP models.
06:04
Here, we could see the duct rises
06:06
running through the second floor slab
06:08
without an opening in the slab.
06:11
Switching to the second floor view,
06:14
we can zoom into the area of the duct rises.
06:17
And we can clearly see the supply and return ducts.
06:22
In this case, the floor opening will
06:24
be cut using the create shaft opening method.
06:28
From the Architecture ribbon, select
06:31
Shaft from the opening panel.
06:36
For the opening, we should use the rectangular option,
06:39
setting the base constraint to 1 foot
06:42
below the second floor and unconnected height of 3 feet.
06:47
Note, this setting will only cut a hole through the second floor
06:50
slab But in a model where a riser passes
06:53
through several floors, the single shaft opening
06:56
could be set to cut through all the necessary floors.
07:01
Set an offset of 2 inches in the options
07:04
bar so that when we pick the rectangle around,
07:08
the extent of the ducts, the hole
07:10
will be automatically offset with a 2 inch clearance gap.
07:20
Switching back to the 3D view the opening objects
07:24
can now be seen.
07:26
And when unselected, it disappears
07:29
to reveal the opening in slab.
07:34
Use visibility Graphics Overrides,
07:37
this time to switch off the display of the MEP model.
07:43
Switching to an analytical model view,
07:46
two new openings can be clearly seen in the analytical objects.
07:56
There is an extra detail that we would
07:58
like to add to the ground floor slab, that
08:01
is a reinforcing edge.
08:03
From the Structure ribbon, select Slab and then select
08:07
Floor Slab Edge.
08:11
Simply Tab-select the perimeter of the ground floor slab
08:16
and the edge will be added around the out edge of the slab
08:21
as can be seen if we take a look underneath the model.
