Detail at top of non load-bearing wall
Detail at top of non load-bearing wall
(OP)
Would like advice on detail at top of reinforced concrete masonry wall. Wall is non load bearing. Gap at top of wall allows for deflection of slab above. Connection to slab required to brace wall out of plane. Gap and connection must be fire protected. Have used a few different details, but all have constructability issues. Would appreciate knowing what detail others use.

The angles are usually about 8" long and spaced at 8 feet on center unless there are intersecting walls, which substitute for the angles.

It's a reliable and easy to built detail. Cheap from a labour end of things, if slightly material expensive. I was taught the detail by an "old hand" at one of the offices I worked in and have found it to be simple and reliable, without any constructability issues.
Let us know what you choose to do,
Good luck,

The fire rating requirement is why I did not suggest staggering the angles, which is of course quite possible for strength, but may or may not satisfy your fire (depending on your code requirements and whether or not blast design is a further sub-requirement of your fire criteria).

The fire rating can be achieved, provided the building official will accept it, by firespraying the angles if they are on both sides, or by fire rated sealants if the anticipated joint closure is not too large.
Another approach I have recently heard described is to provide vertical dowels, into dowel caps inserted into the slab above, with space above the top of the dowel to accommodate the movement. I like the sound of this detail because of the ability to extend the dowel down into the second course. But it also sounds like a lot of work and probably requires a proprietary dowel cap to make the idea work properly.
