In recent years, it is well known that adding steel fiber to concrete significantly increases the ultimate shear strength and ductility of concrete. The test for concrete panels subjected to pure in-plane shear loading is deemed necessary to better understand the shear behavior of fiber reinforced concrete (FRC) members. This research aims to investigate and analyze the shear behavior of FRC panels and propose modified MCFT theory for FRC. Six panel specimens with two levels of concrete compressive strengths (normal strength and high strength) are analyzed in this study. It is found that conventional MCFT procedure is not giving a good prediction to FRC. By adjusting the tensile response of crack FRC members, shear behaviors of FRC panel can be well described.
