Discover the process of constructing a structure using Revit Structure, including precision placement of columns, sheathing, and especially beams. Learn from step-by-step instructions on how to set moment frame beams, girders, joists, brace frame beams, and wood beams to create a complete structure.
Key Insights
- One initial step in the process involves setting moment frame beams. This is done using the Structure panel in the program, where specific beam properties are selected and parameters checked.
- The placement of girders and joists is a crucial part of the process. The former are placed at the roof level, using 3D snapping to ensure they sit atop the columns, while the latter are considered as not bearing from other beams.
- Finally, the placement of brace frame beams and wood beams is essential to complete the structure. These beams have specific properties and are set using 3D snapping, beam lines, and the chain command for continuous linking.

Hello, and welcome back to Revit Structure. Let's get started. Now that we've got our columns set and our sheathing set, let's start placing beams.
Again, we have the moment frame beams to set, so let's go to the Structure panel, Beams, and the first beam we want to set is our moment frame beam, as we did on the floors previously. So let's go to our Properties. Let's scroll down to our 24 at 94.
Okay, let's check our parameters. Okay, we're at the roof. This is going to be a girder, so let's set it.
And we are going to be using 3D snapping on these girders, so let's check it, make sure it's set. What that will do is when we go to pick our reference points, it will snap to the tops of columns. Let's check our parameters here.
We want our offset value to be zero, because again, we are starting at the roof line, not below it. Okay, we have girders. Let's get started.

And again, these are moment frames, so let's set our start connection to the moment frame. And our end connection to the moment frame. Let's set our first one here, and here.
Revit will take a moment and place it at the tops of columns. And let's finish placing the rest of them in the same locations we had as below. Okay, let's go to the other sides.
Now these are going to be considered joists, so let's change those back to joists, because they aren't taking any bearing from other beams. Let's place these. Okay, let's go on to place our brace frame beams.
These are the 21 at 55s. So let's go back into our properties, scroll down. 20 at 55.
And these are not moment frames, so let's take that notation out. Let's zoom in. Again, we have our 3D snapping on.
And at this point, in this line, this is a girder. So let's place it here. And at the other side, opposite here.
Let's finish placing the other two, which are now joists. Again, they're not carrying any beam loads. Place it here, and here.
Let's escape out of that. Okay, let's go back up to the edges, and let's set our beam lines along the exterior face of the building. These will now be wood beams, so let's go back to beam.
Let's go back to our properties. Let's scroll down. And these are going to be the 6 3⁄4 × 16 1⁄2 inch glulam beams.
These will be girders on this face, so let's change that. Again, our 3D snapping is on. Let's check our values.
Our offset is zero. We do not have them as moment frames. Let's change this to girder also.
Okay, let's get started. Let's start placing them. What we can do to help the process is we can turn on the chain command.
This will give us a continuous linking, so we don't have to stop and pick at each one. Let's do the next one. Okay, let's place them at this location now.
We've set our peripheral beams on the north and south face. Let's go to the east and west. Let's place it here and here.
Okay, sometimes we get this notation that the brace may be slightly off. That's because the column may be just slightly higher or lower depending upon the elevation of the sheathing. We can disregard that.
We can move on and finish framing our system. Okay, let's do our interior lines. Now these lines at the interiors are going to change to a 5-1-8 × 16-1-2 inch glulam beam.
Let's again go to our properties, drop down, pick it, and start framing. Let's go to our next line and continue. Let's skip out of that.
As we can see here, Revit has done a little bit of offset on the beams, so let's fix… Actually, that is our slab line, so we are good. Okay, let's take a look at our section and see how we turned out. You notice how Revit has now placed our beams at the top of columns.
You can check our elevations. See, we have an elevation of 1-11-21-30 seconds. If we pick the column, we can see that our top offset is 1-11-21-30 seconds.
So, we've placed our beam framing. Let's go back to our roof and finish up this layout. Okay, let's do our vertical framing, which are 6-3-1-4 × 16-1-2 inch glulams.
These will be considered girders also. Yes, they are carrying four framings. Let's take this and get started.
Again, we get the slightly off axis. That's okay. Let's just continue.
Let's move down to the next line. Continue getting our basic framing in. One last area.
Skip out of that. There you have your basic framing. There you go.
That's it for this video. We'll see you in the next one.
