Hi all. I'm in a pickle with a contractor. I have a pre-engineered building with a typical turndown slab over isolated footings foundation. Building shears are transfered to the slab with hairpin bars. Its my opinion the use of hairpin bars in this manner requires the slab be considered a structural element and subject to the minimum area of steel required by the code for structural concrete. The governing code is IBC 2000 which differs to ACI-318. ACI-318 does not address slabs on grade used in this manner. Does anyone have any information on this subject?
