Frontiers of Structural and Civil Engineering 2009, Volume 3, Issue 2,   Pages 131-136 doi: 10.1007/s11709-009-0027-0

Abstract: Impact compression experiments for the steel fiber–reinforced high-strength concrete (SFRHSC) at mediumstrain rate were conducted using the split Hopkinson press bar (SHPB) testing method.The experimental results showed that, when the strain rate increased from threshold value to 90 s , theincreased about 30%, the elastic modulus of SFRHSC increased about 50%, and the increase in the peak strainmatrix and steel fiber high-strength matrix.
