However, there is a trade-off problem in a fact that large relative displacements are inevitable in the passive isolation systems to reduce the response accelerations of the superstructures. In order to solve this problem, semi-active seismic isolation systems with a controllable friction damper using piezoelectric actuators, a controllable friction damper using a hydraulic system driven by giant magnetostrictive actuators, and a controllable viscous damper using a magnetorheological (MR) fluid damper have been developed. We have shown in our previous studies that the effectiveness of these semi-active seismic isolation systems with the three abovementioned controllable dampers reduce the response accelerations and displacements. In our previous studies, we carried out the excitation tests using a small-scale structure model in order to confirm the effectiveness of these semi-active seismic isolation systems. However, in order to apply the three abovementioned controllable dampers to large structures, it is necessary to increase their capacity. In this study, the controllable dampers are applied to full-scale structures, and the expansion of each damper and performance of the semi-active isolation systems are examined by a numerical simulation. This paper outlines the expansion of these dampers and the simulation results for the seismic isolation effects; further, it summarizes the relative displacement reduction effects of the semi-active seismic isolation systems using the controllable dampers for full-scale buildings.
