摘　　要：通过１０根变截面高度的钢筋钢纤维混凝土无腹筋梁试验，研究了其斜截面承载力的“尺寸效应”；通过１２根钢筋钢纤维混凝土配箍筋梁的试验，研究了钢纤维体积率和箍筋特征值变化对其斜截面承载力的影响规律．最终提出的钢筋钢纤维混凝土梁斜截面承载力计算方法具有广泛的适用性和可靠性．ased on the analysis of the test results of 159 SFRC beams without web reinforcement and 19 SFRC beams with stirrups in literature, additional tests of 10 SFRC beams without web reinforcement were carried out to study the size effect of their shear resistance, and tests of 12 SFRC beams with stirrups were carried out to study the effects o fiber volume fraction and stirrup characteristic value on their shear resistance. The methods proposed in this paper for calculation the shear resistance of SFRC beams has widespred compatibility and reliability.
