| 摘 要： | 在经典修正压力场理论的基础上做了进一步的研究,根据钢筋混凝土受弯构件的剪切破坏机理,考虑上部受压区混凝土和下部受拉区骨料咬合力及箍筋共同提供受剪承载力,推导出截面的受剪承载力表达式.与所收集的国内外有腹筋梁的275个试验结果的比较表明,采用该文提出的受剪承载力表达式计算的受剪承载力与试验结果的变异性较小,可用于钢筋混凝...

| Abstract: | Based on the modified compression field theory,this paper develops an equation to calculate the shear capacity considering the shear contribution of concrete in compression,the shear stress transmitted across crack interface,and the contribution of stirrups based on shear failure mechanism of reinforced concrete members.The proposed equation is verified through a comparison with the experimental results from different sources(275 in total).It was found that consistency between shear strength calculated usin... |
