Research into the bearing capacity of reinforced concrete bent elements strengthened by the FRCM system

Abstract

This article presents the experimental results of reinforced concrete beams strengthened by the FRCM system. To realize the set goal of the work, 4 reinforced concrete beams of real dimen-sions 2100 mm × 180 mm × 140 mm were manufactured. Exhaustion of the load-bearing ca-pacity of all samples occurred due to the fluidity of the reinforcement. After the moment of reaching the flow of the reinforcement, physical destruction occurred in all samples due to the fragmentation of the compressed zone of concrete. Studies of reinforced samples showed that the non-shearing capacity was 16 % higher compared to non-reinforced control samples
