Slab-On-Grade Supporting Cantilever Column/Wall
Slab-On-Grade Supporting Cantilever Column/Wall
(OP)
I have a project where I'm adding some cantilever columns anchored to and existing slab on grade to brace some free standing walls. How can I justify the adequacy of the connection to the slab on grade? Since the slab on grade only has reinforcement for temperature and shrinkage (assuming wire mesh), from a design stand point I'm considering it as plain concrete. I need to make sure the existing slab on grade can take the moment generated from the cantilever column. My thought was to consider a tributary area of the slab as a "footing" and calculate the tensile stresses in the slab and check that vs the modulus of rupture of concrete. If my stresses are less than the modulus of rupture than i'm safe... Your thoughts?

Alternatively, if the wall had all sorts of turns and corners where it was self bracing and the slab only took vertical gravity loads, perhaps then I'd do it.
