Abstract
The aim of this article is to familiarize with the experimental and theoretical study of the load-bearing capacity of BFRP concrete beams damaged in previous studies and brought to failure, reinforced with carbon-plastic fabric in the lower stretched zone and carbon-plastic jackets in the supporting areas under the action of low-cycle sign-repeated transverse loading of high levels with the development of initial data for the physical model of the methodology for calculating the strength of their normal and inclined sections.
The article presents the results of testing concrete beams reinforced with ВFRP, strengthened with carbon fiber reinforced polymer (CFRP) strips in the lower tensile zones and carbon fiber reinforced polymer jackets at support sections, previously tested to ultimate limit state (ULS). The load-carrying capacity of the reinforced FRP support sections of beam structures, brought to the ultimate limit state (ULS), should be determined primarily under the action of bending moment through the critical inclined crack.
The performed experimental and theoretical studies have established the possibility and feasibility of strengthening damaged and brought to the boundary state (ULS) concrete structures with BFRP external fiber-reinforced plastics (CFRP) while observing the established technology. The bearing capacity of CFRP-reinforced damaged concrete beams with BFRP should only be determined for the action of bending moments along normal sections in elements with large (a/d = 3) and medium (a/d = 2) shear spans and along inclined sections in beams with small (a/d=1) shear spans.
