| 摘 要： | 本文首先考虑脉动风力的随机过程性，确定了脉动风力作用下结构随机风振效应的最大惯性力，导出了随机风振系数的概率分布函数；在此基础上，同时考虑平均风力的随机性、脉动风力的随机过程性及其对结构的随机动力效应，提出了等效随机静风荷载的模型、合理地假定了相应的概率分布函数并确定了与荷载设计标准对应的分布参数，从而为结构抗风可靠性分析提供了方便、实用的风荷载模型．

| Abstract: | In this paper, based on the random process model of fluctuating wind foers,the maximum inential force of wind-induced random response of a stucture is determined and theprobability distribution of random gust response factor is obtained first.Sacondly,considering the randomnas of average wind foers,and the random process property of fluctuating wind force and its random dynamic effects on structure,the paper puts forwarda random equivalent static model of wind load assumes the corresponding probabilitydistribution reasonably and determines the distribution parameters according to the loaddesign standards.In conclusion,a practical random wind load model is provided forthe reliability analysis of wind-resistance structures |
