DESIGN OF THE HIGASHI-KOBE BRIDGE, JAPAN

This article describes the 885m long Higashi-Kobe Bridge, which is an important link in the Osaka Bay Route in Japan. It is a double-decked three-span cable-stayed structure, with each deck carrying three lanes of traffic. Its centre span is 485m long. Resistance to earthquakes and strong winds was considered carefully, when designing the bridge's main girder, suspension, and tower frames. Aesthetic considerations were also important in the design. The main girder is a Warren truss with no vertical members. The truss floor has a steel deck, to reduce the superstructure's weight. To resist earthquakes the main girder has been designed so that it can move longitudinally on all supports, supported by the cables attached to the towers. As an extra precaution against unexpectedly strong earthquakes, vane-type oil dampers have been installed at the girder ends, to control large longitudinal displacements of the main girder. For aesthetic reasons, the towers are two straight columns, tied at a relatively low position. Wind load was the main consideration in determining the tower base cross section. The towers were built up using prefabricated blocks. The floor system is an orthotropic slab structure with 12mm thick deck plates, reinforced with longitudinal ribs every 70cm and transverse ribs every 3m.
