Effects of Viscoelastic Dampers on the Improvement of Torsional Response of Asymmetric Buildings

비대칭 건물의 거동 개선을 위한 점탄성 감쇠기의 활용에 관한 연구

The visco-elastic dampers were used to improve the torsional responses of an asymmetric buildings. The modal characteristic equation of an asymmetric structure with added viscoelastic dampers were derived using the complex modal analysis method. Parametric study has been performed based on the modal characteristics, and the appropriate condition for compensating the stiffness eccentricity was investigated. According to the results the torsional response of the asymmetric buildings could be improved significantly once the dampers were properly placed
