Recently, habitability against wind-induced vibration as well as structural safety against earthquakes is required for buildings, in particular for high-rise buildings. Having these requirements in their mind, the authors have developed a hybrid energy dissipation system, which is composed of a hysteretic damper and visco-elastic dampers connected in parallel. For this damper, a buckling restrained brace is utilized as a hysteretic damper. And to enhance the damping performance against very small amplitudes, a thin-layered (thickness 2mm) visco-elastic damper with a load-reducing system during a great earthquake is utilized. Based on dynamic loading tests of full-scale dampers and a vibration test of a real building, it is confirmed that the hybrid damper has wide range of performance of energy absorption.
