摘　　要：文章以某钢结构观景塔为例,对应用粘滞流体阻尼器的高柔结构进行风振响应控制分析。通过MATLAB模拟生成脉动风时程,采用“等效静风荷载法”对安置了粘滞流体阻尼器的观景塔进行风振响应分析,结果表明安装了阻尼器后,可以有效降低结构在风振激励下的水平振动,满足舒适度要求。Taking a steel observation tower as an example,The wind-induced response of high flexible structures with viscous fluid dampers is analyzed.The fluctuating wind time history is generated by MATLAB Simulation,and the wind vibration response of the observation tower with viscous fluid damper is analyzed by"equivalent static wind load method",it can effectively reduce the horizontal vibration of the structure under wind load and meet the comfort requirements.
