Application analysis of energy dissipation and wind vibration control for the high-rise building of Xiangluowan in Tianjin

The wind and seismic resistance engineering applications of viscous dampers in high-rise building projects at home and abroad were listed,and the international relevant department′s researches were introduced,which fully showed that viscous damper has significant effect on structure protection.Taking the practical project of block A09 of Xiangluowan in Tianjin as an example,through analyzing the changes in structure interlayer displacement angle,floor 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 method,respectively.
