Nonlinear FEM and Control Method for Super-Long Span Three Main Trusses and Three Cable Planes Railway Cable-Stayed Bridge

Abstract:

The Anqing Changjiang River Railway Bridge is an important fixed link across the Changjiang River in Anqing both the Nanjing-Anqing Intercity Railway and Fuyang-Jingdezhen Railway. Its main bridge is a six-span continuous steel truss girder cable-stayed bridge with main span of 580 m. The purpose of this paper is to describe some of its main features and FE model for geometrical nonlinearity using the finite element program ANSYS as well as control method of stress-free status for erection of cable-stayed bridge. Based on geometrical nonlinear analysis theories, secondary development of ANSYS using APDL was accomplished.
