摘要
由于GB50009-2001《建筑结构荷载规范》与CECS102∶2002《门式刚架轻型房屋钢结构技术规程》对门式刚架设计中风荷载体型系数取值不同,从现行荷载规范关于体型系数的确定原则、体型系数的来源背景分析及低矮房屋在风荷载作用下所具有的特征等方面,阐明荷载规范GB50009-2001表7.3.1中体型系数应用于低层轻型门式刚架设计的局限性以及采用CECS102∶2002体型系数的合理性。
According to different values of shape coefficient for wind load stipulated in load code GB 50009-2001 and in specification for low-rise light steel portal frame CECS 102 ： 2002, principles of determining shape coefficient in current load code, and the origin and characteristics of shape coeffcient for wind load for low-rise building were discussed. The restriction of shape coefficient in table 7.3.1 in GB 50009-2001 for use in low-rise frame design as well as the rationality of shape coefficient in CECS 102 ： 2002 were explained.
