- Abstract:
- Based on the traditional calculation method of the finished state of suspension bridge and the finite element method, an iterative algorithm for determining the finished alignment of the main cable of multi-tower suspension bridge is proposed based on Ansys Finite Element Analysis. On this basis, the trial design of 3-6 tower suspension bridges is carried out, and the calculation results are compared with those of gravity stiffness theory. An example shows that the finished alignment and internal force of multi-tower suspension bridge can be obtained accurately by using this method. This method can be applied not only to the analysis of finished state of plane cable system, but also to the analysis of space cable system.
