| Abstract: | The structure of the main navigation span of the Shanghai Yangtze River Bridge is a cable-stayed bridge with a X-shaped pylons and the separated double-box steel girder.The main span of the bridge is 730 meters which is the fifth length in the same kind bridges in the world.Large span cable-stayed bridge pylon anchorage usually adopts steel anchor boxes and steel anchor beam structure, the Yangtze River Bridge with steel anchor boxes set inside concrete hollow pylon wall anchorage was introducted in this paper. The structural design was proved with finite element analysis to meet regulations and rules requirements. |
