摘要
某超高耸电视塔主塔高454m,天线高156m,总高610m,风荷载为其主要的控制荷载。采用现在广泛流行的线性滤波法中的AR自回归模型,模拟了该结构具有随机性、时间相关性、空间相关性的51条顺风向脉动风荷载时程样本,并对结构进行了风振响应分析。分析结果表明了本文方法的有效性,为了进一不提高结构的舒适度性能,有必要采取相应的减振控制措施。
A high-rise TV tower is 610 meters tall, the wind load being the mainly control loading. By using the Auto-Regressive （AR） model, 51 samples of fluctuating wind load are simulated which has time and space correlativity and stochastically. Then, the wind-induced vibration response of the structrure is calculated. The results show that this method is effective, and it＇s necessary to introduce into vibration control, so as to enhance the comfortable performance.
