Analysis of dynamic property and seismic response of leaning arch bridge

For complex bridge,time history method(THM) and response spectrum method are both used to analyze the seismic response.According to field type and fundamental period,the standard spectrum divided into ten parts,and earthquake wave producing spectrum,best similar to the standard spectrum in fundamental period part is utilized as the time history load,then two methods generating proximal results.At the same time,seismic wave also meets the time of duration and correlation demand.
