Abstract
Mechanical properties of the laminates reinforced with steel wires based on UHTS (Ultra High Tensile Strength) steel are only slightly worse than popular carbon strips. Thanks to competitive price they become popular strengthening material for concrete structures. The paper presents the results of laboratory tests of beams not efficiently reinforced in shear zone and strengthened along its side surfaces by the L-type overlays made of SRP tape. In addition, in order to ensure a high load-bearing capacity, beams were strengthened against bending. The effectiveness of reinforcement in a comparative test of unreinforced model was analyzed including ultimate capacity, deflection, failure model and strains. The results were used to evaluate the efficiency of SRP shear strengthening.
