| Abstract: | Sanchaji Bridge on Xiangjiang River,which is a self-anchored suspension bridge with steel-box beam(70 132 328 132 70)and uses reinforced concrete diamond structure for its maintower.The design procedures and construction features of Sanchaji bridge are briefly introduced in the paper.It also makes use of the finite element analysis to discuss the effects of member dimension,crossbeam setting and longitudinal damping device to the space stability and stress performance of maintower. |
