Collar joint between cmu and brick grouted solid
Collar joint between cmu and brick grouted solid
(OP)
I am working on a small project where we are replacing an old concrete stair with a few one. The existing landing appears to sitting on a wall that is 8"cmu+4" brick with about 1" of solid grout joint (no air space). The landing is sitting only on brick. I am wondering if I could also use the brick. I always try to avoid attaching to brick veneer which an air space behind it. But since this existing wall has a grouted solid joint, could I consider the brick to be part of the load bearing system and not just a veneer?

The vertical shear between the wythes should be distributed. Even though the books usually do not state it as fact, even joint reinforcement (tab system), if used, provides some comfort for a belt and suspenders analysis.
ACI 530 provides some good information on multi-wythe wall behavior, especially in the commentary section.

Hokie, I'll have to address that too. Good suggestion.
