Analyses of Stresses and Force Transmission Route in Box-Shaped Anchorage Zone for Cable-Stayed Bridges

  • The finite element method was used to investigate stresses in the box-shaped anchorage zone for a cable-stayed bridge in order to give the quantitative description of cable force distribution along principal welding lines,the mechanical characteristics of the main plates and the cause of stress concentration.The research shows that the pad plate of the anchorage box bears about 20% of the total cable force,and its main function is not to bear the cable force but to transmit it to the two webs of the anchorage box.The two welding lines between the two webs and the girder web bear about 80% of the total cable force,and they bear almost equal force.The distribution shape of shear stress on the two welding lines looks like a saddle,and the concentration of stresses on the main plates is caused by in-plane and out-of-plane concentrated forces and bending moments.
