| Abstract: | The cable-stayed arch bridge is a new type of composite bridge.In this paper,the 3-D finite element models(FEM) are erected based on the Fourth Bridge over Xiangjiang River in Xiangtan City for analysising dynamic characteristics of cable-stayed bridges including self-vibration frequency and mode of vibration.The effects of major structure parameters on dynamic characteristics are also discussed.Some suggestions about design of the structure are presented. |
