아웃리거 댐퍼 시스템의 동적응답제어 성능 분석

Recently, Outrigger damper system has been applied to the vibration control of tall buildings. But, Structural characteristics and design method of this system were not sufficiently investigated to date. In this study, the dynamic response control performance of outrigger damper has been analyzed. To this end, a simplified analysis model of outrigger damper system was used. Wind load is used the artificial wind generated by the kaimal spectrum. Analysis results show that outrigger damper system is more effective up to 20-22% in the control of dynamic response compared to conventional outrigger system. it is necessary to select that proper stiffness and damping values of the outrigger damper system. Because, the outrigger damper having large capacity is result in heavy financial burden.
