Discussion on Structural Analysis with Finite Element Analysis Program ANSYS for Suspension Pipe Bridge System

Suspension pipe bridge is a kind of common structural form consisted mainly of main cable wind cable tower foundation anchor system and girder form pipe bridge. The shape and dimension of main cable and wind cable will change with the position and distribution of loads. This paper discusses the analysis on forces and determination of installation dimensions of main structural parts of the suspension pipe bridge by means of finite element analysis program ANSYS. In consideration of nonlinear characteristic of suspended-cable structure the calculation model of the suspension pipe bridge system is established by utilizing the structural analysis modules of ANSYS and the cable shape seeking and static analysis under different load cases are conducted. The program ANSYS gives more rational and correct installation dimensions for the engineering construction than manual calculation.
