If the steel fiber is added to the concrete mixing, the brittle behavior is induced to the ductility behavior and the tensile resistance of the concrete is increased. The mechanical property of the concrete is improved it overalls controlling production and growth of the crack it locals. In this paper, the effect of steel fiber on the settlement performance was examined through the concrete fracture tensile performance experiment by vertically arranging the concrete member using the high strength steel with the yield strength of 500 and 600MPa for the concrete using the steel fiber and the concrete without the steel fiber. In recent studies, it is essential to understand the behavior of the settlement performance in steel fiber reinforced concrete (SFRC) and to verify the applicability of the current regulations for the settlement performance design used in concrete structure. All specimens were applied with the minimum bridging distance to the same width with the diameter of 2 of high strength steel reinforcement. The main variables of the experiment were the mixture of rigid oil, compressive strength, steel reinforcement, and shear reinforcement. The experimental body length was planned to be installed at 1.5 and 0.7 on both sides based on the length of the vertical reinforced high strength steel. The results showed that the steel fiber mixing affected the load-displacement curve. The steel fiber reinforced specimens showed greater stiffness than the non-reinforced specimens and the maximum pullout force was greater than 17.2% ~ 67.8%. Steel fibers have good characteristics of steel fibers because they also improve concrete strength and catch cracks in the cracks. The difference in the history of the settlement length for the design type of the existing anchor was 1.8% ~ 97.9%. The design formula for the existing anchor is valid, but it is not suitable for the tensile performance of the anchor in steel fiber reinforced concrete (SFRC).
