Constructional Mechanical Analysis of the Girder of Shijingshan Cable-stayed Bridge with Single Tower and Single Cable Plane

Abstract

The field data of the girder’s level and key section’s stress of Beijing Fifth-ring Road Shijingshan cable-stayed bridge are presented and analyzed in detail in this paper. The test results are in accordance with the simulative results. It proves that the stress of girder’s key sections of rotating part can meet the requirements of corresponding design and construction code at each stage. The stress state of the whole bridge is reasonable and the girder’s level smoothness can meet the requirements of the design and code. Therefore the construction quality has been under good control.
