Abstract

This paper deals with the behaviour of headed shear stud in a push test using composite slabs with profiled sheeting. A three-dimensional finite element model was developed using general purpose finite element program ABAQUS to model the push test. Shear studs were welded through the deck to the beam and transverse ribs were perpendicular to the axis of the beam. Both, material and geometric nonlinearities were taken into account. The separation that occurs between the profiled sheeting and the concrete during experiments was implemented in the finite element model by assuming a suitable contact between them. The capacity of shear connector, load-slip behaviour and failure modes were predicted and were in close agreement with experimental results. At failure, the vertical separation between the steel deck and the concrete slab was clearly observed in the finite element analysis which undoubtedly represented the true behaviour of an experimental push test. It is concluded that the finite element analysis, if validated properly against test results, could be used as a cost effective alternative to the expensive experimental studies.
