N2 - This research examines the behavior of a fiber-reinforced concrete Ohno beam that fails in shear. The study aimed to determine whether adding fiber to ordinary concrete subjected to shear stress increases its strength and ductility. This work employs the 3D nonlinear finite element method, which uses the multi-surface plasticity approach for numerical modeling. Steel fiber (SFRC), polypropylene fiber (PP), and polyvinyl alcohol fiber (PVA) are investigated. The steel fiber-reinforced concrete (SFRC) Ohno beam specimen possesses the same characteristics as conventional reinforced concrete (RC), including sharply confined cracks, crack bridging, and softening characteristics. Before cracks appear, the SFRC specimen has a higher initial tensile strength than the RC specimens. The initial crack in the PP-FRC Ohno beam was smaller than in the RC beam. In terms of the second maximum peak load, it was superior to conventional RC and SFRC beams. On the other hand, it was discovered that PVA fiber performed the best. The load at the first crack was above the normal RC, and the load at the peak of the second crack was nearly twice as high.
