本文确立了阵风的等级划分方法及相应的等级概率密度函数。在把脉动风压模拟为高斯平稳随机过程,并取结构的第一振型作为考虑结构连续工作概率的出发点的基础上,文中应用级数解法和Poisson假设得到了相应于所有可能等级阵风作用高层建筑和高耸结构在阵风持续时间中动力可靠性的近似计算公式。 This article establishes the gust classification method and the corresponding graded probability density function. After simulating the fluctuating wind pressure as Gaussian stochastic stochastic process and taking the first mode shape of the structure as the starting point for considering the structural continuous working probability, this paper applies the series solution and Poisson hypothesis to obtain the corresponding high-level gust of all possible grade gusts.
