Abstract: Rubber isolators have become increasingly popular for elevated bridges after Great Kobe Earthquake. Several issues have appeared, however, for using rubber bearings. For example, bridges with rubber bearings had come to cause vibration easily due to heavy vehicles, fr om which fatigue fracture had arose at the base of traffic sign poles and lighting poles as well as structural body. Vertical movement alsocaused low frequency vibration at the web plates of steel plate girders. As a device reducing the vertical vibration, new type rubber bearing with piled steel plates at the center of the bearing is developed. This rubber bearing supports vertical force by the piled steel plate and works as ordinal rubber bearing for the horizontal movement for big earthquake. In this paper; cyclic loading test and its seismic performance are described.
