A numerical investigation to study the behaviour of headed shear stud in composite beams with profiled metal decking is reported in this paper. The steel deck was oriented perpendicular to the beam. The analysis of the push testwas carried out usingABAQAS/Explicit with slowload application to ensure quasi-static solution. Both material and geometric nonlinearities were taken into account. Elastic-plastic material models were used for all members except concrete slab for which Concrete Damaged Plasticity model was used. The post-failure behaviour of the push test was accurately predicted, which is crucial for realistic determination of shear capacity, slip, and failure mode. After validation against experiments, the model was used to carry out parametric study to investigate the effect of concrete strength, slab depth and profiled sheeting rib width. It is concluded that this model is extremely useful in understanding the behaviour of headed shear stud in composite beams with profiled sheeting.
