Nonlinear Seismic Response Analysis of Cable-Stayed Bridge under Uniform and Traveling-Wave Excitations
The finite element method model of a 670.56m span cable-stayed bridge was established and the dynamic characteristic and nonlinear earthquake-responses of it under uniform and traveling-wave excitations were systematic studied. Results show that: 1) its former 10 rank frequency are located very dense which shows that more modes shape should be considered when dealing with the dynamic analysis. 2) The traveling-wave excitation has greater effect on long-span cable-stayed bridge, especially on the more flexible component and great attention should be paid to the design of such kind of bridge.
