摘　　要：根据双排碗扣式钢管脚手架稳定承载力试验,在铰接体系理论基础上,针对连续立杆和碗扣刚度等因素对脚手架承载力的影响分别进行了理论分析,提出了稳定承载力计算长度系数的修正计算公式,计算结果与试验结果吻合较好。According to the stability test of double-pole steel-pipe scaffold with bowlbuckle,and on the basis of hinged system theory,this article gives quantitative analysis of scaffold stability,with respect to factors like continuous standards and bowl-shape-fastener stiffness respectively.Updated formulas for effective length factor are also presented,whose results agree with the test results well.

关 键 词：碗扣式钢管脚手架 稳定承载力 连续立杆 碗扣刚度
