Abstract—WuSuBridge of HEIXIAZI Island is cable-stayed bridge with single tower and single plane. The cable-girder anchorage with anchor-box is adopted to connect the cable with the steel girder. Due to large quantities of plates being used in this structure, complex configuration and severe stress concentration, the fatigue behavior of the steel-anchor-box subjected to service live loads need a careful research. According to the theoretical analysis of the anchor structure by finite element method, and design a full-scale test model to simulate the anchor structure. Combined with the design traffic flows and the relevant regulations compute the fatigue loading. The theoretical analysis and fatigue test results show that the stress of the anchor structure is much less than fatigue allowable stress under the fatigue loading. The fatigue performance of the anchor structure is satisfy the regulatory requirement, and has a sufficient safety margin.
