摘　　要：风荷载作用是结构设计的重要内容,了解、熟悉并掌握巴西规范及其与中国规范的异同,对在巴西美丽山二期±800kV特高压直流工程中更好的采用巴西规范进行设计很有必要。该文对巴西规范《结构风力》(NBR6123—1988)和中国规范《建筑结构荷载规范》(GB50009—2012)中的风荷载基本风压、风压高度变化系数、风荷载计算方法、参数取值等方面进行计算、分析、比较,得出两国规范在风荷载作用计算方法的差异。Wind load is an important part of structural design.It is necessary for better using Brazilian code in the design of Belo MonteⅡ±800 kV HVDC Converter Station Project to understand,and master the similarities and differences between Brazilian code and Chinese code.This paper introduced calculation,analysis and comparison about the wind load in the Brazilian code Forces in buildings due to 《the wind》(NBR 6123-1988) and the Chinese code 《Load code for the design of building structures》(GB 50009-2012),including the basic wind pressure,height variation factor of wind pressure,calculation method of wind load and parameter selection,and the differences of calculation about the wind load between the two codes were obtained.
