Research Abstract |
We developed a new earthquake resistant hybrid sytem for houses consisting of a mat foundation, a sliding base and an upper structure with oil dampers. It works as a base-isolated system when ground motion is extremely strong. Under minor ground motions or strong wind, the base does not slide but oil dampers work to decrease vibration of upper structure. By shaking-table tests and numerical analyses, it is confirmed that deflection as well as acceleration can be decreased, making it possible to make use of the house even soon after a severre earthquake.
