Abstract:Concrete slabs reinforced with steel decking have become a leading means of floor-slab construction in recent years. The use of higher strength concretes and shallower sections have led to more emphasis on serviceability considerations in design. A method to predict composite steel-deck deflections is proposed, which is similar in format to the method currently recommended by ACI 318-83 for normally reinforced concrete. Deflections predicted by the recommended empirical procedure, the ACI 318-83 procedure and the method suggested in the ANSI/ASCE Specifications for the Design and Construction of Composite Slabs are compared to experimental results. The proposed method shows a significant improvement over other procedures. The proposed equations are recommended to replace the procedure currently used in the Specifications for the Design and Construction of Composite Slabs.
