摘　　要：介绍了改进的稳健设计法,并引入新的信噪比,考虑的因素包括混凝土强度、水平箍筋屈服强度和竖向箍筋屈服强度.用软化桁架模型分析梁柱外节点抗剪强度,并应用改进的稳健设计法对影响梁柱外节点抗剪强度的因素进行分析,得出了各种影响因素的重要程度,与田口方法相比改进的稳健设计法的分析结果与试验结果吻合较好,应用更加准确、方便.The fundamentals of improved robust design method and a new signal to noise ratio are introduced. Parameters reviewed consist of the concrete strength, the yield strength of horizontal hoop and the yield strength of vertical hoop. The softened truss model is applied to predicting shear strengths of exterior RC beam column joints for seismic resistance. And the improved robust design method is applied to analyze several important factors of shear strengths of exterior RC beam column joints for seismic resistance. The results give the degree of importance of different factors. The result of improved robust design method agrees with the testing result better than Taguchi method. It is more accurate and convenient than Taguchi method.
