Study on lateral stiffness strengthening for 42m deck steel truss girder bridge

Dejun Liu

Abstract

The engineering design case about reinforce for 42 m deck steel truss girder bridge on Ji'nan railway bureau investigated in this paper.By the geat FEM analysis software ANSYS and BDAP(Bridge Dynamic Analysis Program),both the vehicle and the bridge was analyzed with a coupled finite element model to calculate the response of them.It puts forward that strengthen base on bracing system without changing main truss is effective and practical method.
