摘　　要：通过对22个钢筋钢纤维混凝土牛腿试件的试验研究,探讨了钢纤维体积率、剪跨比、混凝土强度等对钢筋钢纤维混凝土牛腿斜截面抗裂荷载的影响,在普通混凝土牛腿斜截面抗裂荷载计算公式的基础上,给出了钢筋钢纤维混凝土牛腿斜截面抗裂荷载的计算公式,计算值与试验值基本吻合。Tests were carried out on 22 steel fiber reinforced concrete corbels with reinforcement to investigate the effects of fiber volume ratio, shear span to depth ratio and strength of concrete upon the cracking-resistance loads of diagonal section. Finally, the calculating formula of the cracking-resistance loads of diagonal section of steel fiber reinforced concrete corbels with reinforcements was proposed based on that of reinforced concrete corbels.
