风力作用下双曲冷却塔壳体的破坏事故屡见报导,引起了国内外力学工作的密切注意。本文按照随机振动理论,采用作者推演的折算系数方法,求出了风振力和风振响应。研究分析表明,折算系数主要决定于单一的结构参数,从而使计算变得简单。应用计算表格已经给出,可供实际应用。 Destruction accidents of the hyperbolic cooling tower shell under wind power are frequently reported, which has attracted the close attention of domestic and foreign mechanics work. In this paper, according to the theory of stochastic vibration, the wind coefficient and the wind-induced vibration response are obtained by the method of conversion coefficient devised by the author. Research and analysis show that the conversion coefficient mainly depends on a single structural parameter, which makes the calculation simple. The application calculation table has been given for practical application.
