Description

This paper addresses the developing of response reduction device of a detached house during earthquake. Reduction devices are composed of shear key and improved composite soil material, which are arranged between the seismic-isolated layers. The mechanical properties of the improved composite soil material are investigated by laboratory tests. Then we confirm the hysteresis characteristics of this system by shaking table tests. Furthermore we investigate the response reduction effects of a house with this device during earthquake by analytical studies.
