摘　　要：本文以合肥电视塔为工程背景,探讨了粘滞流体阻尼器对高耸电视塔在强震作用下地震响应的振动控制。分别进行了电视塔在EL-Centro波、Taft波和人工合成的合肥波作用下,线性粘滞流体阻尼器对合肥电视塔地震响应的控制分析,并对阻尼器的参数进行了优化设计。分析表明,采用最优参数的粘滞流体阻尼器可以明显减小电视塔的地震响应。In this paper, Hefei TV tower is taken as the engineering background to study the vibration control of earthquake response of a tall and slender TV tower by using viscous fluid damper under severe earthquake. The control of the earthquake response of the Hefei TV tower due to the linear viscous fluid damper is analyzed under the El-centro, Taft and artificial simulated earthquake waves. The optimum design of the parameters of the damper is also carried out. It is shown by analysis that the earthquake response of the TV tower can be reduced distinctly by using the optimum parameter viscous fluid damper
