Since Great Kobe earthquake in 1995, the seismic design of infra-structures in Japan was revised greatly in many items. But as far as the bridge piers concerned, the design concept by the conventional single directional seismic force has remained, not taking into account the actual bi-directional horizontal seismic forces. In this study, the strength and ductility of steel bridge piers subjected to bi-directional horizontal forces are investigated experimentally, which afford the basic information to establish the rational design rules. As the first stage of this research, actual seismic responce is idealized into several simple histeretic loading patterns, such as linear, circle, oval, radial, square and octagon types. The different seismic performances are obtained according to these loading patterns.
