Abstract

Shear resisting mechanisms and the diagonal cracking behavior of fiber reinforced concrete (FRC) beams with stirrups were discussed in this paper. Five FRC beams with various types of fibers, which were 30-mm and 60-mm long and made of steel, polypropylene, polyvinyl alcohol, and polyethylene terephthalate, were tested. The method to evaluate shear carried by fibers in FRC beams using tension softening curves was presented. The tension softening curve was used to investigate the force transferred across the diagonal crack from its width, which was measured using the image analysis system. The shear carried by fibers was calculated using the proposed method. In addition, the cracking of FRC beams was studied.
