The mechanical model is presented to describe the structural characteristics of steel veneer shear connectors. The model is designed to predict the performance of connectors under monotonic, cyclic and impact loads. Based on the symmetrical component method, the kinematic hardening theory and the law of conservation of energy, the theoretical formula is deduced. The model and calculation formula can predict the mechanical properties under various loads according to the geometric characteristics and material properties of connectors. The reliability and accuracy of the model were verified on the basis of experimental and finite element analysis results. The mechanical model is very useful for frame analysis.
