| Abstract: | 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. |

| Keywords: | tensile strength self stressing concrete steel fiber reinforced bar |
