Masonry wall reinforcement
Masonry wall reinforcement
(OP)
I am designing an interior non-bearing masonry wall bearing on steel beam. This wall is technically not part of the Seismic resisting system and will be isolated at 3 sides in plane of the adjacent walls and roof. I am in the process of checking to see if it can be unreinforced. If so, will stud anchors welded to the top of the flange and grouted in the cells at 16" capable of keeping the wall in place? Any input is greatly appreciated.

BOCA used to have a table and I believe it is now in the IBC that lists the maximum spans you can go unreinforced with a certain thickenss masonry wall. I would use that as your guide. Is it sitting on a slab or directly on the steel? I would weld rebar to the top of the steel or have rebar bent into the slab and grout solid at bottom two courses. I like to brace the top of the wall also. Put a continuous bond beam at the top course and make a lateral only connection to whats above. Allow for vertical movement. If there is steel above, weld a continuous or clip angles to steel and hilti into bond beam.

As for solid grouting all cells or partial grout, it depends on the local requirements. For example, City of LA allows partial grouted cells where as California Building Code requires that all cells be grouted.

I hope your comment is for areas in non-seismic zones. In California, non-bearing CMU partitions will experience lateral force far exceeding 5 psf. Would you reinforce the walls in this condition?
I haven't practiced outside California too often, so I wouldn't know what's required in non-seismic zones.

In all cases, I apply the requuired loads, and if a non-reinf. doesn't work, I reinforce it. I have done some projects in CA and ya...the lateral is pretty high there for some odd reason. You got big moles out there?

I am waiting for California adoption of the IBC so I can actually "learn" the new code that's been around for 5 years.
