WHITE STEEL FOR OSAKA BAY

A complex steel bridge designed to appear simple and graceful, with a main span of 485 m and side spans of 200 m each, the Higashi-Kobe Bridge will be one of the world's longest cable-stayed bridges. Wind, earthquake and aesthetics were the design determinants, as well as the man-made bay infill site on which the bridge would be built. Suspended form the tower crossbeams, the main girder is designed to move longitudinally on all supports rather than being fixed to the piers and towers, so that the bridge has an unmprecedentedly long natural period of longitudinal sway. This reduces earthquake forces and, hence, size requirements for the tower and foundation. Details of the design, construction and finishing touches are described.
