MODEL TEST FOR FATIGUE PERFORMANCE OF ANCHORAGE IN CABLE-STAYED BRIDGE WITH STEEL BOX GIRDER

摘要：

Cable-girder anchorage in anchor-plate form is adopted to connect cable with steel box girder in Zhanjiang Bay Bridge. Its mechanic behavior is very complicated and fatigue performance of anchorage system under service live-loads needs special attention. The application of anchor-plate anchorage structure in long span cable-stayed bridge is introduced. The characteristics of anchor-plate anchorage structure are investigated and fatigue test of a fullscale model of the anchorage zone is introduced. Combining theoretical analysis with the result get from fatigue test, stress contribution of the anchorage system under cyclic load and static load is analyzed in detail and fatigue performance of the anchorage system under cyclic loads is assessed.
