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.

Maximum Crack

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.
