%X 为了准确计算钢筋钢纤维混凝土梁斜截面抗剪承载能力，设计3组(共9根)不同钢纤维掺量的混凝土梁试验方案。通过对比分析试验结果、我国规范和欧洲规范设计理论，得到以下结论：2种规范进行构件抗剪承载力计算时侧重点有所不同，对于本次试验中的钢筋钢纤维混凝土梁，2种规范设计值相差不大，设计误差值均在-20%左右，具有充足的安全保证。根据本次试验结果分析，我国规范的设计误差主要是因为钢纤维增强系数取值偏小导致的，建议针对钢丝切断异形钢纤维的影响系数βv进行更为广泛深入的试验研究。<br>In order to calculate shear resistance of SFRC beams, experiment scheme was designed for three groups composed of nine SFRC beams with different steel fiber contents. Based on shear resistance obtained from experimental data and theoretical study on Chinese Code and Euro Code, the following useful conclusions are obtained: these two codes concentrate on different aspects while calculating shear resistance, in this experiment, the design values according to Euro Code of shear resistance of fiber reinforced concrete beams with steel reinforcement are close to those of Chinese Code, compared with experimental results. The design errors are both about -20%, both have adequate safety margin. According to the result of this experiment, the design error of Chinese Code is mainly due to the fact that the intensification factor of steel fiber is too low. It is recommended to carry out more extensive and deep experimental research on the intensification factor of special-shaped steel fiber
