In this study, a system combined of viscous damper and displacement controller with hardening type force-displacement relationship is proposed. By applying the proposed system to a multi-story structure, displacement controller device restricts the displacement of the all stories and uniform ductility distribution can be obtained, with no significant change in acceleration and inertia force values. Moreover, an energy-based damper design method, with the assumption of uniform ductility distribution, is proposed to determine the necessary viscous damping coefficient and the adequate gap of displacement controller. The results show that, seismic displacement response of the reinforced concrete multi-story structure is effectively reduced under the target ductility value, with the viscous damping coefficient that is obtained by the proposed method.
