本文通过分析、简化实测的自然界脉动风压相关特性数据,应用概率特征对应等值条件,把随机脉动风压拟合成近似等价的指数风压数学模型,提出用指数风压对结构模型激振的理论,从而为高耸结构风振模型试验中的激振系统提供了一种简便的新方法。 This paper analyzes and simplifies the measured natural wind fluctuating pressure related characteristic data, applies the probability characteristics to corresponding equivalence conditions, and fits the random fluctuating wind pressure into an approximately equivalent exponential wind pressure mathematical model, and proposes using exponential wind pressure to stimulate the structural model. The theory of vibration provides a convenient new method for the excitation system in the wind-induced vibration model test for towering structures.
