The article presents the results of experimental testing of reinforced concrete beams with different shear spans and strengthened by the FRCM (Fiber Reinforced Cementitious Matrix) system. The shear spans were 2, 1.5, and 1. Strengthening was performed for shear span 2 with three vertical strips of composite fabric 70 mm width each. In total, the results of the eight tests (the four experimental samples) are presented. Each beam was tested twice, separately for each support section of the beam A change in the failure type of reinforced concrete beams at shear is shown. It was determined how the bearing capacity and deformability of concrete and transverse reinforcement in all samples changed with the change in test parameters. The use of strengthening strips at the level of 20% of their maximum elongation values was achieved.
