Collision Response of Bridge Girder with Shearkeys Subjected to Seismic Loads
In return for the collision response of bridge girder with shearkey subjected to seismic loads, a simplified dynamic model has been built by using the finite element analysis program Ansys/Ls-dyna. Based on the analysis of calculation results, the motion feature of this model is unfolded. Also, the stress response and characteristic at the bottom of shearkeys are analyzed, which are the most important parameters reflecting the cracking of shearkeys. Furthermore, the deformation of rubber bearing is elaborated to illustrate the collision of bridge girder with shearkeys. Finally, other key properties about the bridge girder of this collision system are addressed.
