| 摘 要： | 介绍了改进的稳健设计法,并引入新的信噪比.用软化桁架模型分析钢筋混凝土短牛腿抗剪承载力,并应用改进的稳健设计法分析影响钢筋混凝土短牛腿抗剪承载力的几个基本因素,考虑的因素包括混凝土抗压强度、剪跨比和钢筋屈服强度.通过分析可知钢筋屈服强度这个因子对短牛腿抗剪承载力最为敏感,剪跨比和混凝土抗压强度次之.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.

| Abstract: | The improved robust design method and the new signal-to-noise are introduced.The softened truss model is applied to analyze shear strengths of RC short corbel,the improved robust design method is applied to analyze several important factors of shear strength of RC short corbel,and the reviewed factors included the concrete compression strength,the shear span ratio and the yield strength of reinforce.The yield strength of reinforce is the most important factor to effect the shear strength of component,next t... |
