摘　　要：提出了集中荷载作用下有腹筋钢筋混凝土简支短梁斜截面受剪承载力计算的软化组合桁架模型(soft enedcombinedtrussmodel),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的试验结果对比符合较好.The softened combined truss model is presented to analyse the shear capacity of reinforced (concrete) short beams with 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.
