Firstly, a high-rise building in highly seismic region is designed under the requirement of architecture. Then a finite element model of the structure is established, and the vibration properties are studied by using Ritz Vector Method. Lastly, the seismic control plan is designed by using viscous damper, and the seismic responses in X and Y direction of the structure with damping devices are analyzed using dynamic history analysis method. The results shows that the viscous damper can reduce the seismic responses of high-rise building effectively, then a economic and reasonable designation can be conducted, although the amount and section of the lateral resistant members are limited. The study of this paper can provide an important reference for seismic control design of high-rise building in highly seismic region.Keywords: high-rise building; highly seismic region；viscous damper; structural control作者简介：季新强，工学硕士，一级注册结构工程师，Email:xinqiangj@sina.com。
