This paper evaluates analytically the flexural behavior of steel fiber reinforced concrete (SFRC) notched beams according to the tensile strength of steel fiber. For this purpose, compressive strength and bending tests of SFRC applying steel fibers with tensil strength of 1,200 and 1,600 MPa was conducted. Strain hardening behavior was observed when using high tensile strength steel fiber. Compression and tensile models were established through test results. For the tensile model, hordijk model and trilinear model were analyzed and compared. The results of analysis showed good agreement when using trilinear model.
