摘　　要：在试验研究的基础上,根据异形柱框架结构顶层边节点的受力特点及传力模型分析,提出了受剪承载力计算的软化斜压杆模型,按该模型推导了异形柱框架顶层节点受剪承载力的理论计算公式。理论分析结果与试验结果分析吻合较好。The paper examines shearing characteristic and mechanism of top story exterior joints in R.C.frame structure with special-shaped columns.By using the theory of softened strut-tie,the formulas for shearing strength of top story exterior joints in R.C.frame structure with special-shaped columns are derived.And the calculating value has been compared with the test results.
