摘　　要：该文对设置粘滞流体阻尼器的高耸结构风振反应控制进行了研究。以某高耸结构为例,采用三维有限元分析软件建立其有限元模型,根据振型分解法推导出设置了黏滞流体阻尼器的高耸结构的风振反应控制方程,并对该结构的反应控制进行数值模拟分析。数值结果表明:采用粘滞流体阻尼器的高耸结构可以有效抑制其风振反应,使该结构其层间位移角和顶层最大加速度均能满足规范的设计要求。The wind-induced vibration response control of a high rise structure with viscous fluid dampers is researched in this paper.Taking a high-rise structure as an example,the finite element model is established by three-dimensional finite element analysis software,the wind-induced vibration response control equation of the high-rise structure with viscous fluid dampers which is based on the modal analysis method is derived,and the numerical simulation analysis of the response control of the structure is carried out.The result shows that：the high rise structure with viscous fluid dampers can effectively restrain the wind vibration response,and the story drift and the top maximum acceleration of the structure can meet the design requirements of the specification.
