Abstract

This study presents the fracture properties of steel fiber concrete. The ratio and notch length of steel fiber in concrete beam specimens, with dimensions of 10cm×10cm×40cm, were selected as independent parameters for the identification of the properties. The volume ratio of steel fiber in the concrete specimen was changed from 0% to 0.5%, 0.75% and 1%. The notch length was changed from 0 mm to 15, 30 and 45 mm. By applying three-point bending tests, J-integral (J ), K , G , deflection strength, and fracture energy Ic Ic F were obtained. Sensitivity analysis was performed to identify the behavior of the dependent variables by changing the volume ratio of steel fiber in the concrete specimen.
