| Abstract: | Based on the experimental study of steel fiber reinforced concrete(SFRC)under impact loading,the behavior of nonlinear visco- elasticity sensitive to strain- rate is studied.The mechanical model and its characteristics of dynamic constitutive relation modified by damage are discussed.A damage evolution modified constitutive equation of SFRC is given.The results obtained from the model are agreeable to the experimental ones. |

| Keywords: | SFRC strain-rate-dependent dynamic damage constrtutive equation |
