| Abstract: |
Extradosed cable-stayed bridge has been used more and more in practical engineering because of its superior structural performance, good economic efficiency and good appearance. In this paper, taking a single cable plane prestressed concrete extradosed cable-stayed bridge as an engineering example, finite element analysis (FEA) is applied to complete the static analysis and stability analysis of the bridge during the construction stage, completed bridge stage and operation stage. In addition, the characteristics of stress distribution of the anchorage zone are analysed by using FEA software and the space finite element method. Finally, FEA software is used to output the cable force influence matrix, and the cable force adjustment and optimization are carried out based on the calculation principle of cable force optimization and combined with Matlab programming. The results can be used as reference for the design and construction of similar bridges. |
