| 摘 要： | 总结了国内外标准的施工阶段风荷载标准值取值规定,并分析了我国主要城市不同重现期风压的关系。以国家标准《建筑结构荷载规范》GB50009—2001的计算公式为基础,对施工阶段的主体结构和施工辅助设施结构,提出了施工阶段风荷载标准值修正建议,通过算例说明了建议的应用。《混凝土结构工程施工规范》GB50666—2011的附录A部分采纳了该建议。

| Abstract: | A summary on characteristic value of wind during construction stage specified in different standards is presented,while the wind pressures of difference return periods are analyzed.Based on the calculation formulae in Load code for the design of building structures GB50009—2001,the revised formulae on characteristic value of wind during construction stage for the main structure and the structures of construction facilities are proposed.A calculation example is given to illustrate application of revised suggestion.Some suggestions are adopted in appendix A of Code for construction of concrete structures GB50666—2011. |
