| Abstract: | In this paper,an engineering design case of a multiple long span X-style concrete filled steel tube(CFST) arch bridge was investigated,and its 3 dimensional dynamic model was created with FEM.The soil-structure interaction was computed by M method.With a consideration of shear deformation effect,the dynamic characteristics of the bridge was analyzed by subspace iteration method and the seismic response of the bridge was respectively calculated by means of the spectrum method and time history method with a c... |
