The seismic isolation structure has a habitability problem that it tends to be vibrated when it is always used. Therefore, we have newly developed a seismic isolation device that controls vibration in the infinitesimal range. The seismic isolation device is an elastic slide bearing and an oil damper integrated, and the performance of the damper in the infinitesimal vibration range was confirmed by vibration tests. We confirmed the effect of adopting it in a building by analysis. We also conducted dynamic tests to verify the performance of the seismic isolation device and put it into practical use.
