摘要:
根据随机振动理论,分别按照星谷胜和M.Shinozuka方法对合肥电视塔顺风向脉动风荷载进行了模拟,并对其进行了检验,得出了符合合肥电视塔动力特性的人造脉动风压时程样本.并利用所得到的脉动风压样本对电视塔进行了顺风向响应分析,分析表明,该塔在脉动风荷载作用下,上塔楼的最大风振加速度响应超过了人体舒适度的要求,有必要进行风振控制.
Abstract:
According to the random vibration theory, the dynamic alongwind load on the Hefei Television Tower is simulated by two different methods, respectively. These samples are proved, and the time-histories of dynamic alongwind load, that correspond to dynamic characteristics of the tower are set up. With these samples, the alongwind-induced responses of the tower are calculated. Analysis shows that the maximum acceleration response at upper turret with the effect of dynamic wind load is far beyond the value of human comfort limit, and the control of wind-induced vibration is necessary.
