The influence of pier types on the seismic response of the continuous rigid frame bridge

The ANSYS-based 3D time-history analysis of earthquake is applied to a continuous rigid frame bridge,and the influence of various piers on the seismic response of the bridge,It is Concluded compared to bridge with solid pier,bridge having hollow pier has a larger displacement,and the axial force and the in-plane moment are smaller,but the out-plane moment of each component is larger.
