| Abstract: | The main navigation span of Shanghai Bridge over Yangtze River is a cable-stayed bridge with main span of 730 m and is an important bridge of the cross-river passage in Chongming District. Based on full bridge aero-elastic model wind tunnel test, an analysis is made of the dynamic characteristics for the bridge both under-construction state and completion state in the near and long future. The paper introduces the process of wind tunnel test and the test results. Based on the wind tunnel test, its anti-wind capacity is evaluated and calculation results presented showing that the bridge is of enough wind stability under both under-construction state and completion state. |
