DEVELOPMENT OF COMPACT VIBRATION ISOLATION EQUIPMENT APPLICABLE TOEXISTING RESIDENCES-RESTORING MECHANISM UTILIZING ROLLER BEARINGS-

摘要

A joint research project was carried out over a period of two years (2002～2003) to develop a practicaldevice to alleviate human and property losses due to earthquakes. As a result of our efforts, we succeededin creating a device (currently patent pending) made from readily available materials that can be easilyinstalled without heavy construction equipment or special skills. The basic performance of the device hasalso been verified with seismic vibration testing.
