Suspended slab porch cap spans
Suspended slab porch cap spans
(OP)
Have a concrete porch cap on a wrap around porch that is 900sf in area, spanning a cold storage room below. Edges of porch cap to be supported by foundation walls. 1/2" rebar tying the cap to the walls 32"oc. Longest span is about 10'.
Layout can accommodate up to 11" thickness and I'm willing to up-size the rebar if necessary. I'd hoped that for cost reasons I would only have to pour the porch cap 6" thick with 1/2" rebar. Can anyone direct me toward span info regarding suspended slab porch caps?

What is a porch cap? Not familiar with that term.

Anyway, the walls under this porch will be left with about 3' of #4 rebar sticking out the top every 24". This will then be bent over and tied into the rebar grid for the cap to tie things all together. Subsequently, the cap spans a room below, but only needs a live load of 30lbs max.

Local engineer speced a 6" thickness with #4 bar.
