خلاصه مقاله:
In this research the effect of short and corrugated steel fiber with low strength on the shear behavior and cracking moment of concrete beams made of high strength concrete were investigated. The main parameters of the test are the amount of steel fiber, amount of longitudinal bars and the changes in the strength of concrete. In this investigation 12 beams were tested. In 6 beams, the concrete strength was equal to 60 MPa and in the other 6 beam, the concrete strength was equal to 90 MPa. For each of these groups two different ratio of longitudinal reinforcement were used and also the volume of steel fiber to the concrete was changed with 0%, 0.75%, 1.25%. The increasing of strength of concrete caused the increase of stiffness and reduction of deflection in tested beams, also by adding steel fiber in concrete, in addition to increase the ultimate strength, the ductility in the beams increase.
