This study examined seismic response reduction technique using relatively little quantity of dampers and small sectional support members. The fifth stories bending-shear model, which consists of one piece of flat spring showing bending behavior and two pieces of vertical springs holding rotary movement of the top, has been examined. The proposed semi-active seismic response control algorithm of the damper force was examined. The method, which based on potential energy of inter-story, controls the hysteretic shapes of the damper. The design method of this algorithm has been examined in this research.
