6" 2-way concrete slab to wall connection
6" 2-way concrete slab to wall connection
(OP)
A current project has a 6" 2-way concrete slab supported by interior steel posts and 8" masonry walls at all exterior edges.
The contractor is pushing to lay the masonry block up to the bottom of the slab with no bond beam or tie beam.
I would like any input on this as I have not seen it done and would like to see more continuity with the wall (btw, the design works without relying on stiffness from the wall). Also, I find no limitation in ACI.
Thanks.

The main concern, then (except the dimensions bewteen structural joints are excessive) is proper behaviour of the joint; the slab will rotate at the support and some notional eccentricity is to be accounted when checking the wall.

The bond beam is not strictly required, but it prevents the slab concrete from flowing down the open cells. The slab should be tied to the block with nominal vertical bars hooked into the slab at about four foot centers.
