Part of: Effects of Damage and Redundancy on Structural Performance


Composite steel deck slabs have continued to gain popularity; today they are one of the predominant means of floor slab construction in most typical buildings. The term 'composite steel deck floor slab' is applied to systems in which the steel deck has some means of providing positive interlocking between the deck and the concrete. Two types of composite action are possible, namely: (1) composite cold-formed steel deck slab and (2) composite steel deck slab-to-support beam. This presentation will concentrate on the first of these two types of composite action. The presentation is divided into: (1) introductory application examples; (2) highlights of the proposed design criteria, and (3) an example design problem based on the criteria.
