Vibration control of high-rise buildings using high-damping rubber damper: (4th report, loading tests of full-size cylinder type high-damping rubber damper and examination of its vibration control performance)

Many vibration control systems, which are divided into a mass damper system and a storey-installation damper system, for habitability or seismic-safety improvement in high-rise buildings have been developing in recent years. However, a passive energy absorbing system will be the most ideal devices if we consider to reduce the structural responses against the various levels of inputs such from traffic induced vibration to destructive vibration. This study has been developed the vibration control system of an energy absorbing type used the high-damping rubber as a vibration control material. We had already cleared experimentally and analytically that the high-damping rubber damper has stable damping performances in wide vibration area through the various loading tests and the shaking table tests. In this paper, the fundamental performances and the vibration control effects of the full-size high-damping rubber damper which was made from the results up to this time is described.
