This paper aims to investigate the shear carried by fibers of fiber reinforced concrete (FRC) beams with different types and combinations of fibers. Eight FRC beams with five types and three combinations of fibers were tested. The results demonstrated that the stress across the diagonal crack and the angle of diagonal crack increased with the increase in fracture energy; in contrast, the diagonal crack length became shorter. The shear carried by fibers was investigated based on tension softening curves. Good correlation between tested results and calculated results was observed.
