Horizontal truss is designed to increase the stiffness of the girder, but cracks are found at the forefront joint after 3years’ operation. To analyze the cause, finite element simulation method is employed. Fatigue calculation is done on the basis of the simulation results according to FEM code. The research indicates that when the structure is working in tension-pressure alternative situation, its loading capacity is sharply reduced, and welding structures are even sensitive to such stress cycle because of serious stress concentration. Operating status should be fully considered to avoid failure in low stress.
