摘要
为了解日本标准顺风向风荷载作用的计算,对比中日标准顺风向荷载计算的差异,介绍了中国标准GB50009—2012《建筑结构荷载规范》及日本标准AIJ—2005《建筑荷载推荐》顺风向荷载作用计算。对比分析了顺风向风载的系数,如体型系数、风压高度变化系数、风振系数,并进一步讨论中日标准间各系数的区别。通过具体算例比较中日标准风载作用的大小,结果表明对于同一场地,无论刚性建筑还是风敏柔性建筑,基于日本标准的基底风载剪力均要高于基于中国标准的基底风载。
To know the calculation about along-wind direction wind load action of Japanese code and to find differences of wind load calculation between Chinese and Japanese code, and this paper introduces calculation about along-wind direction wind load action in Chinese code GB 50009-2012 Load code for the design of building structures and Japanese code AIJ 2005 Recommendation :for loads on buildings. The comparison and analysis are made about the factor of along-wind direction wind load action such as shape factor, exposure factor and dynamic effect factor in Chinese and Japanese code respectively, and the further discussion is made about difference of these factors. The wind load value is compared between Chinese and Japanese code with examples, the conclusion shows that base shear force of wind load based on Japanese code is higher than that based on Chinese code for not only stiff building but also wind-sensitive flexible building in the same site.
