(中电投工程研究检测评定中心，北京 100840)[摘 要] 根据《建筑结构荷载规范》(GB 50009—2012)提供的风荷载计算方法，对比《建筑结构荷载规范》（GB 50009—2001）(2006年版)，分别从主要受力结构计算及围护结构计算两方面，探讨了风振系数βz、风荷载体型系数μs、阵风系数βgz、风荷载局部体型系数μs1、风压高度变化系数μz及基本风压ω0等各参数的修改对风荷载标准值计算产生的影响。[关键词] 风荷载标准值；参数；体型系数中图分类号：TU312+.1 文献标识码：A 文章编号：1002-848X(2013)S2-0360-04作者简介 ：李雪琛，硕士，助理工程师，二级注册结构工程师，Em ail： lixuechen@ceedi.cn。To analysis on the load code for the design of building structures’ modification of wind loadLi Xuechen1, Zhuo Zhongjie1, Zhang Huadong1, Zhai Zhuanmin1（C+E Center for Engineering Research Test and Appraisal, Beijing 100840, China）Abstract：According to the wind load calculation method which provided by Load code for the design of building structures (GB 50009—2012)，combine with Load code for the design of building structures（GB 50009—2001）(2006 edition), characteristic value of wind load was analyzed. Theoretic explorations were separately from the main stress structure aspect and retaining structure aspect. The effects of various factors, such as dynamic response factor and shape factor, on the characteristic value of wind load were analyzed.Keywords：characteristic value of wind load; parameters; shape factor
