| Summary: | Behaviour of composite dry floor slab system constructed using profiled steel decking and plywood panels is studied by conducting linear and non-linear finite element analysis. The parameters considered are steel sheeting and plywood thickness, profile shape of the deck, and single (top) and double skin (top and bottom) plywood panels. The main focus of the study is on the determination of slab strength under bending and load distribution behaviour in two-way action. A bending test of single skin specimen was conducted to obtain load-deflection behaviour for verification of the finite element model. The results of the analysis indicate that the steel sheeting thickness is the main parameter that governs the slab load bearing capacity while plywood thickness minimally affects the slab strength. Slab with double skin plywood can take the load three times larger than that with single skin plywood. Slab made with trapezoidal shape steel deck has a better load distribution in the transverse direction (two-way system) compared to those made with rectangular and dove tail shape deck. The information obtained from this study can be used as a guide for application of composite dry floor slab system. |
