Behaviour of shear connection between steel and concrete parts of steel and concrete composite truss bridges from elastic phase up to plastic collapse is presented. The primary interest concerns the elastic and elastic-plastic distribution of longitudinal shear flow along the connection corresponding to design level of bridge loading. Results of 3D materially non-linear analysis using ANSYS software package is demonstrated together with approximate 2D elastic frame modelling of the shear connection used by designers. Results of both models are mutually compared and confronted with provisions of Eurocode 4 for composite bridges. The non-uniform distribution of the longitudinal shear required for design of shear connection of composite steel and concrete bridges (in both ultimate limit state including fatigue and serviceability limit state) significantly depends on rigidities of the shear connection, steel/concrete parts and concentration of the shear connectors above truss nodes. The most important results from parametric studies are presented and recommendations for practical design suggested.
