Abstract
A finite-element model is proposed to simulate the load behaviour of composite slabs with studs as end anchorages. The model is verified against physical tests on 36 composite slabs with varying thickness of steel deck, diameter and height of the studs, concrete strength and length of shear span. The longitudinal shear strength contributed by the end anchorage is evaluated and compared with the design shear strength of individual studs proposed in different design codes. The contribution of studs as end anchorages to the shear-bond strength of composite slabs is found to be substantial and should be considered in design assessments. A tentative design method to evaluate the strength of composite slabs with end-anchorage studs is proposed.
