Notice – Design of composite beams with composite slabs using profiled steel decking

Rules for evaluating the design resistance of headed stud connectors through-deck welded within steel decking are provided in NZS 3404.1, 13.3.2.2. Due to the pitch of the ribs in the deck, it is normally not possible to provide enough shear connectors to provide a resistance equivalent to the lesser of: the tensile resistance of the…
