Masonry-encasements to steel columns

[Revitator]

Hi

I'm just about to start modelling a masonry-clad steel-framed building in Revit. I've cut some typical column encasements out of a previous (MicroStation) project: Copies attached.

You can see that we have a cavity masonry wall (insulation-filled cavity): inner leaf will be block/CMU, outer leaf brickwork. The inner leaf will divert around the steel columns to make the encasements: It's a standard type of detail for us.

How would you go about modelling this in Revit?

TIA for any hints, what works/what doesn't, etc.

Hey there,

In this type of situation, I have alway made separate walls. Then, because they are within 6'" of each other, you can join the geometry of both walls to create all of your openings.
By doing this method, you have better control over how your walls end and wrap the way you have them.

This is my way. May not be the fastest, but it is simple and easy to control various heights etc.
Good Luck
Steve

Architectural column casings will cut an external wall what they cut depends on the wrapping and core positon of the external wall type. You may alo need to edit the ootb column casings to remove the symbolic lines. Stuctural colums will need to be added separatly.

Thanks, Steven,

Just so I understand: You make one wall element for the inner leaf, and another wall element for the outer leaf, all round the building? Then you join the leaves together where necessary so that the doors and windows will cut through both leaves?

Yes, I've just had a go at that, and can see that it works. Neat technique, Steven. Thanks!

You get to create (manually) whatever wall endcaps/wraps you want at each opening, so you do get a lot of control. The downside is that you have to draw a bunch more walls. It'd be handy if you could draw things like this in Revit using the compound walls.

Thanks, Rhys,

Yes, I think I see how that works. The wall structure is modified: The blockwork inner leaf is not in the core, so it wraps the column shape. The insulation zone *is* in the core, so it just fills out the interior of the column shape (see attached Wall wrapping 3.gif)

How do you get interior walls to play nicely with this external wall? When I just tried, the inner wall cuts right through the inner leaf and insulation zone (see attached Wall wrapping 2.gif). You could disallow the join, but then the plaster face on the inner leaf will be left uncut.

Thanks, again.

Hi all,

Well, building on Steven's approach, above, I've made a couple of wall corners that seem to work ok (see attached). The main walls are conventional compound cavity walls, and the inner and outer leaves of the corner encasements are assembled out of separate wall elements. The right hand one seems more stable than the left hand: If you copy the left hand one, the wall joins get screwed up.

Hey there,
Looking good!

Thanks, Steve,

I'll post again if I find problems doing it this way.
