| 摘 要： | 本文提出并推导了全方位风荷载作用下高层建筑动力可靠性分析方法及相应的简化计算公式。文中用一定保证率的结构风振随机响应取代了Davenport抗风可靠性分析方法中的结构风振确定性响应,并由此给出动力可靠度计算公式及其简化形式,提高了可靠性分析的准确性。该方法不但可以分析高层建筑的安全度,也可以分析高层建筑的舒适度。

| Abstract: | This paper represents the analysis method of dynamic reliability of tall buildings under wind loads in all directions and deduces simplified formulas corresponding to this method. The certain structural response under wind loads in the analysis method presented by Davenport is replaced by random structural dynamic response under wind loads with proper ensured ratio in this paper. Then the calculating formulas and their simplified forms are proposod. The accuracy of reliability analysis is raised by using this method. This method not only can be used to analyse the degree of security of tall buildings, but also their degree of comfort. |
