This article provides a comprehensive guide on constructing a model in Revit Structure by placing columns for lateral resisting frames and vertically loaded elements. It takes readers through the process of selecting the appropriate column sizes, setting parameters, and placing them in the correct direction and location in the model.
Key Insights
- The article demonstrates how to load the three different types of columns that are commonly used in construction: a 14x211 for the moment frames, a 14x120 for the brace frames, and a 14x43 for the vertically loaded columns.
- Initial placement of the columns can be done in a vertical mode by rotating them and aligning them according to the engineer or designer's specifications. The placement can be modified at any level of the building, and the columns can be set to reach any specified level, like the roof.
- After placing the columns, they can be connected to the concrete columns by adjusting the base offset. This is crucial for the overall design since the columns need to be connected in the model.

Hello and welcome back to Revit Structure. Let's get started. Now that we've got our basic model started, let's start working vertically.
This means we're going to start placing columns for our lateral resisting frames and our vertically loaded elements. Let's first go to Structure, Columns, and here we have a 10x49. We want to load three columns that our designer has given us.
So let's go to Edit Type. Let's go to Load in our dialog box. Let's go down to Structural Columns, Steel, W Shape or Wide Flange Columns.
Here we have another dialog box giving us our variety shapes. The three columns he has given us to build our model with at the moment frames are a 14x211, so let's go down and find it. Here are the 14 inch columns.
What this designation means is the column is 14 inches deep and it's 211 pounds per linear foot. That's his first one. The second one is a 14x120 for the brace frames and a 14x43 for the vertically loaded columns.
Hit OK. Hit OK again. Let's go over to our Wide Flange Columns now and pick our moment resisting columns which is the 14x211.
Okay, we're going to place these at the locations that the engineer or designer has given us. We notice that our column is in a vertical mode. We need it horizontal to our plan.
So let's rotate it by simply hitting the space bar. Now let's start placing them. But let's check our parameters first.
What we're looking for is height or it's going up the building which is correct and we want to go to the roof. You see we can take it to any level we have in the building and we know that these are going to go to the roof. So let's start setting them.
Our first location is here and you notice that it snaps to the grids automatically. So let's place it. Let's go to the next one.
When the grids change the different color that's our location that we want to because it's at the intersection of the grids. We see now that we need this one in the strong direction which is vertical to the sheet. So let's place it by hitting the space bar.
There you have it and let's continue. Again we need this one in the strong direction which is horizontal to the plan. Rotate it and place it.
And one more set at the top of the sheet here. Let's rotate it and place it. Okay that's it for our moment resisting columns.
Let's go to our brace frame columns now. We don't have to get out of the command which makes it efficient. We go to our drop down and pick our 14 × 120.
Okay let's start placing those. Now again we need this in the strong direction. This is where our first brace frame is going to be.
So let's rotate this, place it, place it, and this one is vertical to our plan. So let's rotate it, place these columns, rotate, place these columns, rotate one last time, and place these columns. Okay we've placed our brace frame columns.
Let's go to our last element which are the vertical load bearing columns. Okay and the designer has given us a 14 × 43. Let's pick it.
Let's go to the places where the columns are. Again we want these columns in the strong direction which is horizontal to our plan. Let's pick it.
Let's place it. Let's place this one. Place this one.
What we're going to do is place these at the remaining positions where we don't have columns. Let's place that one. Scroll up and find the elements where we don't have columns.
Place it. Again let's finish out. Place it.
Two more. One last one. Okay there we placed our columns.
Now let's escape out of that or we can go to modify and pick it twice and we're out of that command. Let's zoom to extents zx and take a look. Okay we have a fairly consistent plan.
Let's take a look at it in 3D. Okay looks very good. Let's take a different view.
Let's scroll in down at the base. You notice that the column doesn't quite touch the concrete column below. Well we need these connected in our model because that's how our design works.
We have to have them connected. Let's go back to a side view and let's just grab all the columns. Let's go to our parameters.
We know that our concrete columns are nine inches below finished floor. So let's go to our base offset because we're at level one and we're going below level one. Let's pick it and we know that we are nine inches below that level.
So let's place nine inches. Let's go into the view. Automatically changes our column.
Let's take one more look at our columns and we now have connected columns. Very good. Let's get out of this view.
Go back to our plan view and that's it for this video. We'll see you in the next one.
