Title: Study on analysis methods for seismic response of long span cable-stayed bridge with twin towers
Abstract: In this paper,a practical project is taken as research background which is double pylon cable-stayed bridge with main span of 416 m.Two artificial seismic waves and two seismic records were selected to analyze the seismic behaviors by the response spectrum method,time history analysis method and power spectrum method.The result shows that seismic responses of the girder and main tower are basically identical under the effect of artificial seismic wave.The response spectrum analysis results of them are between the other two methods under the effect of the natural seismic wave.For stay cable,time history analysis results has great difference compared with other two methods’ results.Therefore,researchers can choose response spectrum method to analyze seismic response of girder and tower,and time history analysis method for stay-cables.
