为掌握高强箍筋活性粉末混凝土（ reactive powder concrete，RPC）梁的抗剪性能，通过6根T形梁的抗剪试验，获得了抗剪承载力试验值，并将试验值与压力场理论值进行了比较，探讨了压力场理论应用于RP C梁抗剪分析和承载力计算存在的问题，充分考虑斜裂缝截面上钢纤维拉拔阻力的抗剪贡献，对该理论进行了改进。并将剪切试验结果与塑性剪切理论、粘结滑移理论和法国规范等进行了比较，分析现有抗剪理论的适用条件、存在的问题，这些对揭示RP C梁抗剪破坏机理、建立承载力计算理论与设计方法有参考价值。

To grasp the shear strength properties of reactive powder concrete ( RPC) beams with high strength stir-rup, through 6 T-shaped beams test, the shear strength test values were obtained.The test values and the theoreti-cal values of the compression field theory were compared and the questions of applying the compression field theory in the analysis and calculation of shear capacity for RPC beams were also discussed.The modified compression field theory was proposed by considering the shear crack resistance improvement from the contribution of the steel fibers at the diagonal crack during pull out.Results of the shear test were also compared with the plastic shear theory, the interfacial bond shear strength theory and French code specifications.An analysis of problems facing the existing theories and their applications was also conducted.The analysis results and comparison conducted on the different shear capacity theories provided a solid base for future researches on the shear failure mechanism and further devel-opment of shear capacity design models for RPC beams.
