| Research Abstract |
Base isolated structures are effective system for reduction of seismic response acceleration, but large response displacement occurs. Therefore enough wide clearance in isolated story must be required, and too large response displacement may occur by extreme severe earthquakes or ground motions including long period vibration components. The purpose of this study is to develop the base isolation system with effective reduction of response displacement and control of response acceleration. By the results of this study, effective and simple semi-active control method based on the response displacement values in isolated story only, and simple friction damper with joint mechanism that works only in case of too large response displacement, are proposed.
