| 摘 要： | 修正压力场理论认为有腹筋构件的受剪承载力由沿裂缝面传递的剪应力和穿过裂缝面的箍筋提供,忽略了受压区承担的剪力,受剪承载力计算结果偏小.基于修正压力场理论,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,提出截面受剪承载力计算方法.与所收集的国内外有腹筋梁的275...

| Abstract: | In the MCFT,shear capacity of RC members is considered to be resisted by cracked concrete and stirrups.So,the shear capacity calculated by MCFT is underestimated due to ignortion of the shear carried by concrete in compression zone.In this paper,a further study was made based on the modified compression field theory.A method for predicting the shear capacity considering the contribution of the concrete in compression,shear stress transferred across the crack interface,and stirrups based on shear failure mec... |
