Structure Design of the Prestressed Cableshauled Bridge of Qingdao Sailing Vessel/Zhen Wei, Li Weizheng, Gao Wei(Beijing Institute of Architectural Design, Beijing 100045, China)
Abstract:The design for gallery bridge is accomplished with the guideline of multidefenses. The effect of prestressed cables which has improved the behavior of the structure is estimated through FEM method. The variation of support reactions and the inner forces of structural members and prestressed cables are analyzed when the structure is under temperature load. According to the obtained numerical results, the connections for supports are designed. All the calculated results and design contents have been used to guide the construction of the project.
