【摘要】 阐述近年来冷弯型钢骨架在低层住宅中得到广泛应用的原因,并进一步介绍了这种新型结构体系荷载路径的复杂性。详细分析低层冷弯型钢骨架结构住宅设计的荷载路径,其中包括竖向荷载路径和横向荷载路径。在横向荷载路径中,重点介绍了冷弯薄壁型钢建筑抗侧力设计的两种方法:从属面积法和相对刚度法。最后,指出这些荷载路径中都没有考虑系统效应和构件的相关关系,这对工程分析是有利的。更多还原

【Abstract】 In this paper,the reason why the cold-formed steel framing has been widely used in the low-rise residential housing is explained.Moreover,the complexity of the load path in this new structural system is introduced.Subsequently, the structural design load path of low-rise residential cold-formed steel framing is detailedly analyzed,including the vertical load path and the lateral load path.In the lateral load path,the two design methods of the lateral force resisting system (LFRS),Tributary Area Approach and Relative Stiffness Design Approach,are stressed.Finally,this paper indicates that the system effects and their relationships are not considered in these load paths,which is advantageous to the engineering analyses.更多还原
