本文研究了TMD对北京奥林匹克公园中心演播塔在强风作用下顺风向风振响应的振动控制效果。基于随机振动理论，利用M.Shinozuka方法对该塔的顺风向脉动风荷载进行了数值模拟，得到了6条顺风向脉动风荷载时程曲线；利用二维模型研究了该塔的三维空间模型，并验证了二维模型的正确性和可靠性，而且利用二维模型进行减振控制研究，大大节省了计算时间；以该塔顶层的顺风向风振加速度响应为优化目标，对TMD的参数进行了优化研究。结果表明，该塔的顺风向风振加速度响应超过了规范的容许值，设置TMD后该塔的顺风向风振加速度响应有明显的减小；在TMD最优参数下，该塔顶层的顺风向风振加速度响应和位移响应的减振率分别为20.2%和42.7%。TMD吸收了大量的能量，对该塔的顺风向风振响应有明显的控制作用。

In the paper, Beijing Olympic Center Broadcast Tower is taken as a project case to investigate wind-induced vibration control with tuned mass damper (TMD) under the fluctuation load along wind direction. First of all, based on the random vibration theory, fluctuating wind load along wind direction of this tower is simulated by means of M. Shinozuka method, and 6 correlated time history curves are obtained. Secondly, 3D model of the Tower is investigated by use of 2D model, the accuracy and reliability of 2D model is verified, and calculated time is extremely saved taking advantage of 2D model. Finally, the optimal TMD coefficients are obtained regarding the wind-included acceleration response of upper story along wind direction as optimization objectives. The analysis results show that the maximum peak acceleration response of the tower along wind direction under dynamic wind load is far beyond the allowable value of the code, the wind-included responses are decreased greatly with TMD, and, with the optimal parameters of TMD, the peak acceleration and displacement wind-responses of the upper story along wind direction are reduced respectively by 20.2% and 42.7%. TMD dissipates a large amount of input energy and plays an important pole in the wind-induced vibration control of the tower along wind direction.
