| Abstract: | Taking the continuous rigid frame bridge as the engineering background,this paper uses finite element analysis software,Midas Civil,to establish the model of dynamic analysis and make the modal analysis.On the basis of this,this paper adopts the response spectrum method and time history analysis method to calculate seismic response of the structure respectively and compares and analyzes the results of the two methods,and the conclusions can provide relevant basis for seismic design of the long -span continuous rigid frame bridge. |
