Abstract
Strengthening the reinforced concrete elements using polymer fibers continues to interest many researchers. In this context, an experimental study has been completed to evaluate the reinforcement on shear behavior of beams. Different fiber band positions were applied to beams in nodal zones. The four-point bending tests have been performed. The results have shown that the inclined bands by 45° with respect to the beam axis provide better results compared to those obtained by orthogonal bands (90°), in strength, stiffness, and ultimate load, as well as deformations. In addition, the use of these bands increases the bearing capacity by reducing the arrow and limits crack widths and ensures better behavior of these structures.
