| 摘 要： | 推导了一种计算非高斯风压时程峰值因子的解析方法。该方法利用Hermite矩模型将非高斯过程表示为标准高斯过程的表达式,并利用该表达式通过高斯过程的峰值因子最终推导出非高斯风压时程峰值因子的表达式。同时将该方法的计算结果与用极值概率分布计算的结果进行了对比,结果显示出该方法具有较好的计算效果。

| Abstract: | This paper deduces an analytical moment-based procedure for calculating peak factor of non-Gaussian processes.In the procedure,Hermite model based on monments(skewness,kurtosis,etc) and standard Gaussian process are used to express non-Gaussian process.Using peak factor of Gaussian processes and Hermite model,an expression for peak factor of non-Gaussian processes is derived.Comparisons between the results of the procedure and those calculated by method of extreme value probability distribution are performe... |
