This paper discusses the characteristics of the dynamic response of a structure with semiactive control system. Shaking table tests were performed on a one-story steel structure model, which was controlled by the simple semiactive control system utilizing Magnetorheological fluid (MR) damper. Two proposed control method of a damper force were examined. One is based on potential energy, and the other one with additional control of hysteretic shape. Both methods use relative story deformation. At the tests, three kinds of damper support members were examined in order to clarify the influence of the support stiffness on control effectiveness. By comparing experimental results, proposed control method, which based on potential energy with additional control of hysteretic shape, is found to be better than the other control method particularly in the case of using soft support member.
