Based on the mechanism of the seismic shear key, a new twolayer seismic shear keys which have seismic energy dissipation characteristics is proposed. The structure and design principle are introduced in this paper. A collision analysis model in transverse was built with contact element. Then a bridge was analyzed, some comparative analysis were conducted between the seismic response of the new two-layer seismic shear key and the seismic response of traditional shear key using nonlinear time history analysis method. The results show that the new two-layer seismic shear key can effectively reduce the maximum impact force between the main girder and the shear keys without significantly increase the structural internal force demand and displacement demand. This could reduce the damage of the bridge caused by the lateral collision. This could also reduce the risk of span loss for the collision between the main girder and the shear key in transverse. It could be noticed from the results that the selection of seismic waves has a critical influence to the bridge seismic calculation.
