| 摘 要： | 根据性能设计的要求,高层建筑的抗风设计需要考虑人员舒适性要求。本文提出了用于结构顺风向风振响应分析的广义脉冲响应函数法,用来计算随机激励和结构响应之间的传递函数,这样就可以计算高层建筑结构在风荷载作用下的动力响应特性,并用动力可靠度计算结构在脉动风荷载作用下的舒适度失效概率。

| Abstract: | To meet the requirements of the performance based design,it is necessary to take the comfortable feeling of people living the building when designing tall building resisting wind loading.In this paper,a generalized impulse function method is proposed applicable to the along-wind loading response of structure,which is used to calculate the transfer function between the random excitation and response of the structure.The statistic response parameters of the tall building resisting wind loading are obtained based on the transfer function.The failure probability of comfort under dynamic wind force is acquired by using the theory of the dynamic reliability. |
