The static failure can be seen as a special fatigue failure, which means the static failure is the fatigue failure only bearing one cycle under the ultimate-strength loading. By learning from the analysis of fatigue damage, the stress- strain curve and damage of steel fiber reinforced concrete under uniaxial loading have been studied in this paper. The damage evolution equation can be derived from the damage theory, and it can be used to describe the relationship between the damage variable and strain. According to the strain equivalence principle, the corresponding constitutive equation considering damage can be obtained. Finally, comparisons among test results, the model and ansys simulation results show that the model is suitable to describe the uniaxial stress-strain curves of steel fiber reinforced concrete.
