000011653 520__ $$2eng$$aOver 1000 base-isolated buildings have been constructed this 25 years in Japan and recently, some engineers have been trying to design innovative projects based on the merits of base-isolation systems. This paper introduces one of such projects, using a semi-active base isolation system combining variable oil dampers with the conventional passive base isolation system. The system was developed to improve habitability by reducing acceleration during small and medium-sized earthquakes. The system is equipped with two types of oil dampers: passive dampers with a fixed damping coefficient and variable oil dampers that can be switched between two primary damping coefficients. And then, a mega-structure, consists of both 4-RC bearing-walls and steel super-frame, was applied to this project. These 600mm-thick RC bearing-walls are main design motif as well as main structure for lateral loads. In this paper, an overview of the building and the semi-active variable damping system will be presented. Subsequently, the results of a time history response analysis in the event of an earthquake will be presented, and the effectiveness of the system in reducing acceleration will be indicated.
