1 Building Structure Vol. 43 No. 11 Jun A09 TU TU A X Application analysis of energy dissipation and wind vibration control for the high-rise building of Xiangluowan in Tianjin Wan Yixiu 1 Chen Yongqi 2 Wu Lianjie 1 Ma Liangzhe 2 Hu Qinghua 1 Xue Hengli 2 1 Beijing R&F Properties Development Co.Ltd.Beijing China 2 Beijing Qitai Shock Control and Scientific Development Co.Ltd.Beijing China Abstract The wind and seismic resistance engineering applications of viscous dampers in high-rise building projects at home and abroad were listedand the international relevant department's researches were introducedwhich fully showed that viscous damper has significant effect on structure protection. Taking the practical project of block A09 of Xiangluowan in Tianjin as an examplethrough analyzing the changes in structure interlayer displacement anglefloor shear force and wind vibration acceleration the obvious seismic reduction effect and wind vibration control effect of viscous damper were obtained. Finally the additional damping ratio of viscous damper in different cases was estimated by the equivalent contrast methodrespectively.
