| 摘 要： | 利用正交试验设计法对影响钢筋混凝土短牛腿抗剪承载力的各因素进行分析，考虑的因素包括混凝土抗压强度、剪跨比和钢筋屈服强度。通过分析可知剪跨比对短牛腿抗剪强度最为敏感，混凝土抗压强度和钢筋屈服强度次之。希望本文内容可作为进一步研究钢筋混凝土短牛腿受力性能的依据。

| Abstract: | Shear strength of RC short corbel is analyzed through orthographic design method, and the factors reviewed included the concrete compression strength, the shear span ratio and the yield strength of reinforce. The shear span ratio is the most important factor effecting the shear strength of component, the next one is the concrete strength, the factor with minimum effection is yield strength of reinforce. It is hoped that this could be a base for following research on mechanical performance of the short corbel. |
