Fracture tests were carried out in order to investigate the flexural behavior of SFRC (Steel Fiber Reinforced Concrete) structures. Sixty three SFRC beams were used in the tests, the fracture mode, the relationships between loading and strains, and the relationships between loading and mid-span deflections of the beams were observed under the three point bending loading. From the test results, the effects of steel fiber contents and a/h ratio on the concrete flexural behavior were studied, and the stress intensity factors and the flexural strength of SFRC beams were calculated. According to the results of regression analysis, predicting formulas for the flexural strength of SFRC beams are also suggested.
