Abstract:The cable anchorage zone is a key part of the control design of cable-stayed bridges, and many large-span cable-stayed bridges at home and abroad have conducted specialized analysis and research on the anchorage zone. Based on engineering examples, this paper introduces the common connection types of cable beam anchorage structures for large-span steel box girder cable-stayed bridges - anchor box type, pin hinge type, anchor plate type, and anchor pipe type. Summarized the structural characteristics and finite element calculation, static load testing, and fatigue testing methods of different connection types. Analyzed the force transmission mechanism and stress concentration phenomenon of four types of anchoring structures, proposed structural measures for reasonable transmission of cable force and reduction of stress concentration phenomenon, and clarified the issues that should be paid attention to in design
