Abstract
The results of experimental studies of reinforced concrete beams shear strength without transverse reinforcement reinforced by the FRCM system are presented in this article. The purpose of this study is to establish the distribution of reinforced concrete beams shear deformation reinforced by the FRCM system under the action of loads of different levels. According to the investigation program, four prototypes were tested. The tests were carried out using an improved technique, by testing each sample twice. Samples were strengthened by composite system FRCM at 0, 0.3 and 0.5 levels of the control RC beams bearing capacity loading. According to the obtained data, graphs of tensile deformation in inclined cross section and area of their distribution were constructed. The maximum effect of using the strengthening tapes for shear strength reinforcement was set at 26 ... 57%. With the increase in the load level, which amplifies the sample, the strengthening effect changes.
