| Abstract: | This paper analyzed the base seismic isolation response of continuous beam bridge, and analyzed its power in detail. For the bridge structure with hollow pier,it firstly analyzed the vibration characteristics,which directly affected the dynamic response of structure. Then it used the time-history analysis method to analyze the seismic response of the structure. The paper also compared the time-history response results with or without isolation. |
