摘　　要：提出了集中荷载作用下无腹筋混凝土简支短梁斜截面受剪承载力计算的软化桁架模型.该模型考虑了斜裂缝出现后混凝土应力-应变软化的特性,满足平衡方程和协调方程,理论计算结果与所收集到的试验结果对比符合较好.The softened truss model is presented to analyse the shear capacity of reinforced concrete short beams without web reinforcement subjected to concentrated load.The equilibrium,compatibility condition and the softened stress-strain relation of the strut are considered.The theoretical prediction is in good agreement with the test result.
