Aiming at the problems of complicated structure and unclear fatigue performance in anchorage area of cables and beams in single-cable-plane partially cable-stayed bridges, this paper carries out finite element numerical simulation and static and fatigue test of full-size model of anchorage area of cables and beams in Chongqing Qiansimen Jialing River Bridge, and studies fatigue performance of its manufacturing process and structure detail. The test results show that the actual anti-fatigue performance of structure is perfect.
