| Abstract: | In this paper,the 3-D finite element models(FEM)are erected based on the Fourth Bridge over Xiangjiang River in Xiangtan City for analyzing the influences of various factors on the lateral sta- bility of cable-stayed bridge.These factors include the rigidity of arch,the rigidity and location of lat- eral connections,the sloping angle of arch,and so on.Some suggestion about the design of the struc- ture is presented. |

| Keywords: | cable-stayed arch bridge lateral stability lateral connections sloping angle |
