大直径钢管塔风振时程分析及风振控制研究
Time History Analysis and Control Design of Large-diameter Steel Tube Tower Subject to Wind induced Vibration
【摘要】 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。
【Abstract】 A large-diameter steel tube tower is one of new types of tubular structre.Since a large-diameter steel tube must be treated as a thin-walled shell,its structural analysis and design are quite different from that of the conventional tower Based on static analysis and real projects,the time history analysis and control of wind-induced vibration are studied A new method to control vibration is proposed using a suspended mass pendulum,and its related parameters are investigated Numerical examples indicate that the suspended mass pendulum is an economic and effective equipment to reduce the wind-induced vibration of the large-diameter steel tube tower
【Key words】 towers; tubular structures; dynamic structural analysis; (control of wind-induced vibration); vibration dampers; (mass pendulum);
