影响深梁抗剪承载力因素的综合分析

利用正交试验设计法、稳健设计法及改进稳健设计法对影响钢筋混凝土深梁抗剪承载力的各因素进行分析，考虑的因素包括剪跨比、混凝土抗压强度、水平钢筋屈服强度和竖向钢筋屈服强度。深梁的抗剪承载力对剪跨比这个因素最为敏感，混凝土强度次之，水平钢筋屈服强度、竖向钢筋屈服强度影响最小。与稳健设计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。目的是为以后钢筋混凝土深梁的试验、设计和施工提供基本依据。

Analysis of Influence Factors on Shear Strength of Deep Beam

Shear strength to reinforce concrete deep beam was analyzed by means of orthographic design method,robust design method and the improved robust design method,and the factors reviewed included the shear span ratio,the concrete compression strength,the yield strength of horizontal reinforce,and the yield strength of vertical reinforce.The shear span ratio was the most important factor to affect the shear strength of component,next to the concrete compression strength,the minimum factor was the yield strength ...
