Based on the finite element model of a rigid frame bridge, modal analysis is performed, and then the earthquake response of bridge is calculated respectively by spectrum method and time history method. The differences of seismic response characteristics between high piers and low piers are analyzed. Structural style’s influences on seismic response of piers with different heights are compared. And the strategies on vibration mitigation for low pier are investigated. The results indicate that the characteristics of piers’ earthquake response differ complicatedly, and that the low piers and high piers suffer severer response respectively under longitudinal and transverse earthquake. It’s also found that changing structural style and setting bearing-damper restrainers reasonably can effectively mitigate not only the vibration of piers but also the deformation of superstructures and the shear force of bearings.
