摘　　要：通过直接拉伸试验 ,测量了配筋钢纤维自应力混凝土的抗拉强度 .试验参数包括 3个自应力等级、3个纤维体积率、4种配筋率 .试验结果表明 ,在钢筋和钢纤维联合作用下 ,自应力混凝土的抗拉强度得到明显的提高 ,并由统计分析给出了配筋钢纤维自应力混凝土的抗拉强度计算公式 .Uniaxial direct tensile experiments were carried out to obtain tensile strength of self stressing concrete reinforced with steel bar and fiber. Parameters of experiments included three self stressing grades, three contents of steel fiber and four reinforcing ratios. It is concluded that tensile strength of self stressing concrete restrained by both steel fibers and reinforced steel bars is significantly increased. Formulas are suggested by statistic analysis.
