Based on the fatigue test, 8 steel fiber reinforced high-strength concrete beams are studied, the influencing factors of crack width are discussed in the paper, and the calculation method of crack width under fatigue load is investigated. Based on the analysis of test results, the formulas are put forward. The results show that adding steel fiber into the high-strength concrete beams can prevent the development of the fatigue crack, fatigue crack widths are decreased by 26.0%~121.0% and the calculated values have good agreement with test date.

Through the three-point bending test on the specimens of steel fiber reinforced high strength concrete (SFHSC) and plain high strength concrete (HSC) with the size of 100 mm×100 mm×515 mm, the effects of influencing factors including the fiber volume fraction (ρf) and relative notch depth (a/W) upon the fracture energy and the work of applied force (gravity and external force) were studied. The results show that the effect of ρf upon the fracture energy is more obvious; the variation tendencies for the increment ratio of the fracture energy and that of the work of applied force are different under different factors; the fracture energy is dependent on the work of external force. Based on the test results, the formula was established for calculating the fracture energy.

The effect of volume fraction of steel fiber and the strength of reinforcement on the maximum crack width of steel fiber reinforced high-strength concrete beams was analyzed based on experimental results. In addition, the formula to calculate the maximum crack width of steel fiber-reinforced high-strength concrete beams was established.

Through the three-point bending test on the specimens of steel fiber reinforced high strength concrete (SFHSC), the effects of influencing factors including water-cement ratio (W/C) and the fiber volume fraction (ρf) upon the critical value(JC) of J integral were studied. The results show that the variation tendencies of JC are different under different factors. JC meets the linear statistical relation with W/C, ρf, respectively.
