Stress Analysis of Integral Joint in Three-Truss Steel Truss Arch Bridge

Gonglian Dai

Abstract

With the construction of Dongpingshuidao Bridge is a four-line truss arch bridge with span of(99+242+99)m in the Wuhan-Guangzhou high-speed railway,integral joint E11 in middle truss is analyzed by using shell element in the ANSYS,local stress has been founded too strong in the structure.In order to resolve this problem,joint design has been modified.The improvement of the joint makes it have the sufficient function of bearing and transfer force by improving the node structure.
