Revit Structure Framing Modifications: Coordinating and Modifying Structural Elements

Hello and welcome to Revit Structure. Let's get started. Now that we've completed our revisions at the basement level, let's start moving up our structure to see what other revisions we have to make with our newly relinked architectural model.

Let's go to our Project Browser. Let's go to Level One under the Structural Plans. Let's pick it twice and here we see the newly relinked architectural model.

We can see here that our stair is properly coordinated, so we don't have any changes here. We don't have any changes here because our elevator is still nicely coordinated, but the Architect has come in with a new stair at this level. Since it starts here at this level and goes up, we don't have any changes at this level, so let's move on.

Let's zoom all. Let's move up to the second level again. Let's go to, yes, the second level.

Let's go to the Project Browser. Let's go to Level Two under the Structural Plans. Pick it twice.

Okay, here we see we have the newly relinked architectural model, but we haven't enhanced it yet to a background. Let's do that, but first let's get rid of all of the hidden windows in the back by using a simple command, Close Hidden Windows. We pick that.

Now all we have open is our Structural Plan at Level Two. Let's modify our architectural link to be what we need as a background. Okay, first thing we want to do is we want to go to the View tab.

Pick it. Let's go to Visibility/Graphics in the Graphics panel. Let's pick the tool.

Go to our Revit Links tab. Okay, here we can see our visibility is checked on. Let's make it a true background and halftone it.

Let's go to our Display Settings, Custom. Let's set this to Fine as our Detail Level and our discipline to Architectural. Okay, that sets our overall parameter.

Now we want this Linked by View. Let's pick this and the way it's linked right now, it's linked to the High Roof view. We want it to be linked to the Level Two view, which is what we're working in.

So let's pick it. Let's apply. Hit okay.

Let's apply. Hit okay. Okay, here we can see our revisions at our Level Two.

We can see our stair is still well coordinated. No changes here. You can see our elevator is still well coordinated.

No changes here. But we do have to make revisions in this area where the new stair has been placed. Let's get started.

First thing we want to do is we want to make a cantilevered connection at this column because we're going to move this existing beam out to this line so that we can create an opening for this stair. First thing let's do, let's make this a moment connected beam. So let's tab.

And as the highlight shows us, we have the beam. It's W21x50. Let's pick it.

Let's go check its parameters. We have a start connection and we have an end connection. Since this is the end of the beam, let's pick the end connection.

And here we have three modifications we can make. Cantilever moment, drag connection, or moment frame. It's not a moment frame and it's not a drag connection.

So what we have is a cantilevered moment. Let's pick that. And as we can see, it creates an open triangle that says we have a moment connection.

Not a moment frame, but a moment connection. Now let's create a beam to extend this cantilever to this line so that we can move this beam to this position. Where we want to go is our Structure tab and our Structure panel.

We want to go to Beam. Where we want to go now is find the W21x50 beam. We'll pick here and we scroll down until we find our W21x50.

Okay, let's pick that. And as we know at this level, we have a 2½" concrete on a 3" steel deck. We have negative five and a half inches at top of beam.

So let's change our Z offset value to negative five and a half inches. Let's pick that. We'll set that to negative 0 5.5. And that will give us five and a half.

Now we know we have a start connection that we want to be a cantilever moment because we have the end connection of the previous beam as a cantilever moment connection. We'll pick here. Now we will place our beam.

We'll go to the midpoint of the column, pick it, and extend to the intersection of these two grids, two foot three inches away. Here we have a W21x50. Let's modify.

Go to Modify and escape out of that and change its, not its discipline, but change its capacity or structural usage to a girder. Okay, now that we've done that, let's move our existing beam to this grid line, which will set it at the column at the end of the beam. So let's pick the beam.

Let's tab. And when you hover over an item, it will identify it. Let's pick it.

And now we have a Contextual tab to Modify. Let's go to Modify tab. Let's go to the Modify panel and the Align command.

Let's pick that. Let's zoom in a little. Let's go to our grid line.

That's where we want to take it to, so we'll start there. Now we'll pick the beam that we want to move. Let's pick it.

And there you have it. And we get a dialog box. Can't keep elements joined.

That's okay. Let's unjoin them. And there we have the beam in position.

Okay, while we're in the Modify tab, we want to join these corners. We'll go to our Trim command. Let's pick it.

Let's pick the new beam that we just placed and the new cantilevered beam. And they're already joined. Okay, so here we have the column.

Let's modify out of that and see where our node is. Our node is at the center line of the column. We now have that in position.

What we are going to do now is create a shaft for this new stair. So let's go to the Structure tab. And under the Opening panel, we'll go to the Shaft tool.

Let's pick that. Okay, and as you can see, we have parameters here for the length of our shaft through the building. We don't want it going through the roof, so let's set our top constraint.

We want it to go to level five. So what we wanted to do is just pop through level five. Okay, what we're going to do is we're going to go to Pick Lines and start picking our perimeter lines.

Pick this one, this one, this one. Oh, not that one. Let's go back.

Let's undo that. Let's be careful when we pick them. We'll pick that one, this one, this one.

And since we have the stair on our beam, we'll pick just to the inside. We'll pick this line right here. Okay, now since we've done that, let's go again to our Modify panel and our Trim command.

Let's trim our corners. Okay, now that we've done that, let's go up here and in our draw, we've got Symbolic Lines. And what this will do, we'll create an X out all the way up at each floor line that we will see as our open area.

Now that we've done that, let's go to our Mode panel, Finish Edit Mode. But first, let's check our parameters again. We're up to level five as our top constraint.

We want that to pop through that fifth floor. So let's give it a plus two feet elevation. Now we see we have our bottom constraint at Level 0.

Well, we don't want to take this shaft to the basement. We want it to stop at level two, but we want an opening at level two. So let's take our base offset just below.

We'll give it a negative two feet. Okay, now that that's set, let's go to our Mode panel. Let's go to our Finish Edit Mode.

Okay, there we have a shaft. Let's take a look at it in three dimensions. Let's go to our Project Browser, our 3D views.

Let's pick this twice. Let's find a corner. And there we have now, let's see if we can find it, our new shaft for our stair.

Very good. And you see it's two feet above our fifth floor and two feet below our second level. Okay, let's close this.

That's it for this video. We'll see you in the next one.
