Akashi Kaikyo Bridge, Tatara Bridge, Kurushima Kaikyo Bridge

Akashi Kaikyo, Tatara, and Kurushima Kaikyo Bridges linking Honshu to Shikoku is the longest suspension cable-stayed bridge and the first trio suspension bridge in the world. Based on the newly developed design and construction and experience accumulated in Honshu-Shikoku Bridge project, we completed this large bridges the wind resistance technology applied to this bridges was developed with the project. Tuned mass damper (TMD) systems and dampers between the stiffened girder and tower are used in the Akashi Kaikyo Bridge, and dimple surface cable for damping rain vibration is used in the Tatara Bridge. The girders of the Kurushima Kaikyo Bridge erected by all hinge erection and direct lifting on an international sea lane, where aerodynamic stability was confirmed.
