The elastic modulus of high-strength steel fiber reinforced concrete was measured 37 GPa to 41.98 GPa. Comparing the difference value of the measured stress and the stress calculated by the regression analysis results were within ± 1 MPa. Measured data acorrding to applied LPF was more stable than unapplied LPF data. but, it was slightly different.
