Abstract (2. Language): 
In this paper, high velocity impact test of SFRHSC was conducted with SHPB experimental technique four series mixture of SFRHSC were used: C100V4, C100V3, C100V2, C100V0.And the steel fiber volume fraction ( f v ) were 0, 2%, 3% and 4% respectively. The primary objective of this research is to enhance the understanding of the response of SFRHSC to high strain rate impact. The anticipated results of the study are determination of dynamic material properties and failure mechanisms of SFRHSC. The crack characteristics of steel fiber reinforced and plain concrete are investigated in the SHPB test. Analyzed the relation between the character on the Crack Surface of Concrete and material properties and the impact pressure. Also the multiracial characteristics are given on the Crack Surface of Concrete. The crack distributions of steel fiber reinforced concrete are investigated. The crack resistance effects of fiber are analyzed from the degree of closeness and uniformity.
