Analysis of deformation and strengthen of truss steel bridge based on ANSYS

Hou Rong-we

Abstract

Taking 64 m double line railway truss steel bridge as background,the modeling analysis to double line truss steel bridge was carried out using ANSYS,and the strengthen and deformation of this truss steel bridge under several cases combination effects were analyzed in detail.The results showed that the whole deflection and internal force of longitudinal and cross beam of this bridge satisfied the safe requirement of bridge design.
