Time-History Analysis of Lowpylon Cable-Stayed Bridge with Moving Loads

Abstract:

Established space dynamic analysis model of nonlinear structure in accordance with the unique mechanical characteristics of Lowpylon Cable-stayed Bridge. As the Example for the program about 90+128 meters spacing lowpylon Cable-stayed Bridge of houhu in Wuhan,Simulated the whole process of automobile loading bridge ,calculated eigenvalues of moving loads. Adopted computing skills,using nonlinear supperposition theory analysed time-history and discussed the influence about vibration of transverse and longitudinal because of different velocity. The results show that the research using nonlinear supperposition method to study the dynamic response of Cable-stayed Bridge under moving load is reasonable and effective.
