| Abstract: | Sancha Xiangjiang River Bridge of Changsha is a steel box girder self-anchored suspension bridge with a span combination of (70 132 328 132 70) m.Its pylon adopts reinforced concrete diamond type structure.After presenting the design idea and structure character of the pylon,the Paper,by means of finite element software,analyzes how the size of components,the design of beam and the longitudinal damping device influence the loading performance of pylon and its spatial stability. |
