| The state-of-the-art of earthquake resistance study on continuous rigid frame bridge is reviewed firstly, then analyze the excellence and disadvantage of every seismic response analysis methods and the method of time-history dynamic is mainly discussed. Calculation models of bridges are proposed with finite element methods, and the dynamic property of continuous rigid frame bridge is calculated by the advanced analysis program ANSYS.The method of time-history analysis of earthquake is applied to structure based on the basic theory of the seismic response analysis. The main work in this thesis includes:1,The method of time-history analysis of earthquake is applied to various piers of continuous rigid frame bridge, and summarizing different response .2,Based on the facticity of bridge, studying the influence of the vertical component of earthquake to the seismic response of the bridge;3,Analyze the influence of the wave passage effect to the anti-seismic properties of continuous rigid frame bridge;4,The method of elasto-plastic time-history analysis of earthquake is applied to continuous rigid frame bridge, analysing the influence of elasto-plastic to the seismic response of the bridge.
