CMU Partition Wall Bracing at Metal Roof Deck
CMU Partition Wall Bracing at Metal Roof Deck
(OP)
All,
How are interior non-load bearing cmu walls typically braced at the top when the roof structure is metal deck over steel joists? When the roof structure has been concrete, I have used the sandwich angle detail where the angles are anchored into the concrete, but in this case where there is just 20 ga. roof deck I feel like the roof deck would deform with any lateral load that is put on the angles? See the attached drawings. Thanks!

You could always add some tube steel in the ribs and attach red-iron angle to that (assuming the ribs are perp. to the wall as you drew)

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Or use some deflection vertical deflection clips attached to the Zees and a rigid connection to the CMU... This will allow some rotation so you may need to tie the two kickers together horizontally mid height.?
Or bring the cmu to 2" below zee and use said vertical deflection clip directly

Edit: Sorry, Eric. I didn't see your post before I responded and it's the same thing that I was getting at.
