| 摘 要： | 本文研究了高耸电视塔结构基于被动摩擦阻尼器的风致振动控制问题。文中建立了电视塔结构的三维有限元模型和二维等效动力分析模型。随后建立了电视塔结构的受控运动方程和风荷载模拟方法。在此基础上以合肥电视塔为背景，进行了结构风振反应控制分析和相应的参数研究。分析表明，被动摩擦阻尼器可有效地抑制结构的风振反应。通过合理地选取阻尼器参数，可以获得满意的减振效果。

| Abstract: | The wind-induced vibration control of a high-rise television tower was conducted here by using passive friction dampers.A three-dimensional finite element model and a two-dimensional simplified dynamic model of the television tower were established respectively.The equations of motion of the controlled tower were developed and wind loading was numerically simulated.The Hefei television tower was taken as an example to investigate the feasibility of the proposed control approach based on passive friction dam... |
