Longitudinal shear resistance of composite slabs

Verification methods for longitudinal shear. currently in use, are empirical. This applies for both the m-k method as the Partial Shear Connection method. Parameters and mechanisms determining the behaviour of the shear connection in composite slabs are not directly considered in these methods. A new approach is launched to model the behaviour of a shear connection based on the physical behaviour of the shear connection. First step of the validation of the approach is the experimental. theoretical and numerical analysis of the interaction forces between concrete and sheeting. Possibilities for application of the new approach will be discuseed using other series of experiments.
