以大直径钢管为结构主体的钢管塔是一种很有发展潜力的新型塔。大直径钢管是空间薄壁壳体，其结构分析设计与传统的杆系塔架有很大的不同。在静力分析的基础上，结合具体工程研究钢管塔风振时程分析及风振控制，提出了利用悬吊质量摆进行钢管塔风振控制的方法，分析了控制参数对控制效果的影响。数值算例表明，悬吊质量摆能够有效地减小钢管塔风振反应，是一种经济实用的控制装置。
The steel pipe tower with large diameter steel pipe as the main body is a new type of tower with great development potential. The large-diameter steel pipe is a thin-walled space shell, and its structural analysis design is very different from that of a traditional bar-type tower. On the basis of static analysis, combined with the specific engineering study of the wind-induced vibration time history analysis and wind-induced vibration control of the steel tube tower, a method for controlling the wind-induced vibration of the steel tube tower by using the pendulum mass pendulum is proposed, and the influence of the control parameters on the control effect is analyzed. The numerical example shows that the suspended mass pendulum can effectively reduce the wind-induced vibration response of the steel tube tower and is an economical and practical control device.
