This report deals with the seismic design of the Higashi-Kobe Bridge, which is a long-span cable-stayed bridge. In this bridge, the main girders are supported by all towers and piers in such a way that the girders are all movable (herein referred to as “all free”) in longitudinal direction. This supporting method was adopted with an aim to lengthen the fundamental bridge period to a reasonable long period. By using this supporting method, the effects of the inertial force of the superstructure on the bridge towers and the caisson foundations were greatly reduced, thereby resulting in a more rational and economical bridge design.
