Experimental investigation of RC beams strengthened with externally bonded BFRP composites

Objectives The goal of this article is to examine the behavior of reinforced concrete (RC) rays that strengthen superficially the basalt fiber-reinforced polymer (BFRP) fabrics. We found out that one ray without BFRP and seven rays enveloped within numerous lay-up arrangements. The importance of the study is to improve the flexural capacity of rays, using fiber-reinforced polymer procedure and examine the over-reinforcement technique. Methods Interestingly, we have examined under two-point loading, one BFRP fabric sheet flexure. Results Loads corresponding to the first crack/delamination and ultimate failure of the beams have been verified. Moreover, we have recognized the types of failure and load contrasted with deflection graphs that have been strategized at outstanding ray locations. Novelty Our investigation has unraveled the increased flexural strength of the strengthened RC rays after using coating. Additionally, we have applied pressure to the BFRP fabrics on both sides of the beams. Moreover, we have improved performance with flexural strength, ductility, and failure. Our results are novel and show that the flexural capacity of the wrapped RC rays increases by 46.6%. The ductility increased by 84%, and unfortunately, we had failed the FRB and the concrete had crushed.
