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,结合《建筑结构荷载规范》GB50009—2001(2006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等各参数修改对风荷载标准值计算产生的影响,以供工程技术人员运用新荷载规范参考。In this paper,according to the wind load calculation method the load code for the design of building structure( GB 50009—2012) provided,combining with GB 50009—2001( 2006 edition),characteristic value of wind load was analyzed. theoritic 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. The conclusions are valuable to the engineering application.
