Since the through-type cable-saddle anchorage structure was adopted on the Yakiho-minami and Yakiho-kita Bridges, it has been widely used in inclined-pylon cable-stayed bridges. This paper introduces the application of the improved anti-slip anchorage-type saddle structure on the Mitanigawa No.2 Bridge and its full-scale model test. The tests include basic tests, performance tests of the saddle anchorage device, and the variation of tension-difference transmission.
