Abstract
In recent years, the number of earthquake isolation structure has been increased. The most of earthquake isolation structure is applied the rubber bearings. However, rubber bearing is not fit to use for light-weight structure such as wooden house. Because natural periods depend mass of superstructure. Therefore the diameter of the rubber bearing narrows according to reduction of the mass, and effective area of rubber bearing becomes small according to changing rubber shape. And then the device can not support superstructure. In this study, we propose new isolation system for light-weight house using rubber bearing and friction mechanics. This paper describes result of numerical analysis in this system.
