Semi-active Vibration Isolation Using MR Damper for A Building-like Structure

摘要：

In this paper a gain-scheduled(GS)controller for a semi-active seismic isolation system is designed for a multi-degree-of-freedom structure which has two-degree-of-freedom on the horizontal plane without consideration of coupling of the x-and y-directions.The experiments on a x-y shaking table using some kinds of seismic wave are carried out to verify the performance of isolation of the GS controller used simultaneously.It is demonstrated that the GS controller can adaptively vary the damping coefficient according to various earthquakes and can suppress not only the first floor acceleration but also the relative displacement of isolation layer.
