In base-isolated buildings using passive isolation devices, large horizontal displacements between the ground and the superstructures are needed to achieve effectable reduction in response accelerations of superstructures. Therefore it is necessary to keep the margin space. In this study "semi active base isolation" is proposed. Which can reduce response accelerations, and reduce displacements of buildings more than passive base isolation. Further more it never supplies buildings with energy, so it is a safety system. In this study vibration of buildings is controlled by semi active control with friction controllable damper using piezoelectric actuator, H^∝ control is applied to the control theory.
