Abstract
In Japan, it is important to consider the structural seismic safety in architectural and civil structures, because a lot of earthquake breaks out. It must also be examined the mechanism and the structure which can expect to reduce the structural responses. The research and development of the base isolation system for the light-weight house has been carried out in recent years, although the isolation system has been applied for comparatively large structure such as office building and condominiums until now. In this study, the new base isolation system for the light weight house using friction and rubber bearing. This paper describes the basic concept and the efficiency of proposed system from a seismic response analysis.
