Influence of Load Arrangement on Composite Slab Behaviour and Recommendations for Design

摘要

A parametric study of the behaviour of composite slabs consisting of profiled steel sheeting and concrete is presented. The FEM program DIANA was used to model the slab as a two-dimensional structure. Non-linear material and interface properties are considered as well as discrete cracking of the con- crete. The main parameter is the horizontal shear transfer between the sheet- ing and the concrete: this is the varied with respect to strength, ductility and influence of strain level in the sheeting. The FEM simulations have been validated by comparison with full-scale tests.
