Max Load on Composite deck

Max Load on Composite deck

Max Load on Composite deck

(OP)
Hi All

I have to design a composite mezzanine slab in a factory setting. The max load is around 520 lb/sq.ft (approx. 3.62 psi/25kN/m^2).

I am aware that as per BS, for such heavy loads the metal deck is considered as a permanent shuttering and only the concrete slab is considered designed to span between beams

Does AISC have any loads beyond which composite action is not to be considered? Any references will definitely help.

RE: Max Load on Composite deck

You might check out the Steel Deck Institute publications for limitations. Published capacity tables usually top out at a certain uniform load (12 kPa?). The logic, I think, is that beyond a scertain uniform load, there is a high probability that the loads will really be concentrated and therefore not well suited to composite construction.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
