Study on Earthquake Isolation System with Sliding Rubber Bearing for Light-Weight Houses

Abstract

Recently, the number of earthquake isolation structure has been increased. The most of earthquake isolation structure is applied the rubber bearings. However, light-weight structures such as wooden houses were not applied the isolation device, because it is difficult to apply the rubber bearings, for example, the diameter of the rubber bearing narrows according to extension of the natural period of the rubber bearing, and the device can not support superstructure. In this study, the purpose is development about isolation system for light-weight houses. we propose that the structure is supported with the sliding rubber bearings and the sliders. In this paper, result of numerical analysis in this system was reported.
