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.Keywords:viscous damper; energy dissipation; wind vibration control; toggle作者簡(jiǎn)介：萬(wàn)怡秀，一級(jí)注冊(cè)結(jié)構(gòu)工程師，設(shè)計(jì)研發(fā)中心總結(jié)構(gòu)師，Email：wanyixiu@qq.com。參考文獻(xiàn)［1］LAUREN D CARPENTER, FARZAD NAEIM, MARSHALL LEW, et al.
