Prediction of longitudinal shear resistance of composite slabs with profile sheeting to Eurocode 4

Composite slab incorporate profile sheeting is widely used for multi-storey buildings construction throughout the world. The profile sheeting not only providing the temporarily support to the wet concrete but also formed an integral part of the composite slabs, it provides the resistance to vertical separation and longitudinal slippage between the steel concrete interface. Longitudinal shear resistance of the composite slabs is difficult to predict theoretically and the Eurocode 4 method to predict the longitudinal resistance rely on experimental testing. The most common mode of failure of the composite slab is by longitudinal shear and loss of interlocking at the steel-concrete interface. This paper presents the testing of the composite slabs in accordance to the Eurocode 4.
