摘　　要：本文针对高烈度区高层建筑的结构设计及减震方法进行了研究。首先,针对高烈度区某高层建筑,在满足建筑要求的条件下,进行了常规结构设计;随后,建立了该结构的整体有限元模型,采用Ritz向量法对结构进行了模态分析,研究了该高层结构的振动特性;最后,利用粘滞流体阻尼器,对该结构进行了减震设计,并采用动力时程分析的方法,研究了不同地震波作用下结构在X向和Y向的动力响应。结果表明,采用粘滞流体阻尼器能有效降低高层结构的地震响应,从而在控制抗侧力构件数量与截面的情况下,经济合理地完成结构设计。本文的工作为类似的高烈度区高层建筑减震设计提供了参考和借鉴。The structural design and seismic control method of high-rise building in highly seismic region are studied. 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.
