摘　　要：依据Rilem应力裂缝口宽度法,考虑T-梁翼缘对抗剪的贡献,建立了混杂纤维钢筋自密实混凝土T-梁的抗剪承载力公式,与GB50010-2002、CECS 38:2004、Rilem应力-应变法进行了对比,所建立的公式较好地估计了混杂纤维钢筋自密实混凝土T-梁的抗剪极限承载力.According to the method of stress-CMOD relationship in Rilem, ultimate shear load formula of hybrid fiber reinforced self-compacting concrete RC T-beam were founded with considering contribution to shear of the T-beam flange. The calculation value of the formula founded was compared with that of GB50010-2002, CECS 38：2004 and method of stress strain relationship in Rilem. The result indicate that the formula in the text can evaluate the ultimate shear load of hybrid fiber reinforced self-compacting concrete RC T-beam well.
