| 摘 要： | 本文针对强台风登陆频繁区域的某塔架结构,根据保护要求利用其消防水箱设计了TMD强台风保护系统,给出了设计参数,并在不同风速下,计算分析了TMD台风保护系统的减振效果,计算分析结果表明,TMD对加速度响应的控制效果约30%～50%,对位移响应的控制效果为16%-35%,减振效果理想,对塔架在台风作用下可起到较好的保护效果。

| Abstract: | The TMD defending typhoon disaster system was designed used of the fire water tank to protect the tower structure in coastal region.The damping effect of the TMD system was analyzed at kinds of wind velocity,at the same time the design parameters was shown in the paper.The result shows the acceleration controlling effect achieves 30% to 50%,the displacement controlling effect achieves 16% to 35%.The damping effect is preferably.The tower can be protected by the TMD system under the condition of the strong typhoon. |
