DESIGN CONCEPT OF THE TRANS-TOKYO BAY BRIDGE

This paper introduces the design concept of the Trans-Tokyo Bay Bridge in Japan, which is a group of continuous girder bridges. The bridge is 4.4km long, with 42 piers. The span over the navigation channel is 240m long. There are alluvial sand and clay layers 5m to 20m below the sea bed. Steel box girders with orthotropic decks have been adopted as superstructure, because of its light dead weight and rapid construction. The bridge is designed to have long continuous girders, to increase its seismic resistance. Composite steel piers with steel piles are used for piers 1 to 12. For piers 3 to 13, the girder and the piers are fixed with hinge joints, except for the end piers. From pier 13 to the shallow water area, piers are concrete and relatively stiff, so that rubber bearings are used to obtain a multi-span continuous bridge. Expansion joints are used to handle earthquakes and temperature changes. A special device is attached to the girder ends, to prevent the girder from falling from the piers in the event of an earthquake; it is designed to work after the expansion joints and bearing stoppers collapse.
