The control system consists of magnetorheological fluid (MR) dampers which were set up in each interstory level. MR damper whose damping force is variable according to applied electric current is one of the semiactive control devices. The proposed control method of the damper force was based on potential energy of inter-story and in addition controlled the hysteretic shape. Shaking table tests were performed on a onestory steel structure model. In the tests, three kinds of damper supporters were examined in order to clarify the influence of the support stiffness on the damping properties and control effectiveness. Effectiveness of the proposed method was examined by comparing the numerical results and the experimental results. In the case of using soft support member, the seismic response increases as damper force exceed a critical value. However, the proposed control method is found to be better than the conventional ones. For such control system, the hysteretic control and support member stiffness are significantly influential on effectiveness of the seismic control.
