This paper proposes a system which uses "Variable Stiffness and Damping Mechanism" as a member of actively controlled structure. Natural period and comprehensive damping factor of a structure are changed to reduce its response by means of the "smart member" which can change its local damping coefficient. In this paper, basic property of a unit of proposed mechanism is investigated and the result of complex eigen value analysis is shown. Both active and passive methods are discussed. Three-story-building like steel model was employed to carry out shaking table test to verify the proposed feedforward algorithm. (1) Feasibility of the proposed system that employed "Variable Stiffness and Damping Mechanism" was experimentally verified. (2) Damping augmentation and resonance reduction were realized by the proposed feedforward algorithm.
