This article discusses the behavior of a reinforced concrete deep beam that has been strengthened with GFRP sheets. The GFRP shows many essential and necessary properties such as low weight to strength ratio, non-corrosive, high fatigue strength, high tensile strength, etc. In this paper, four deep beams were cast, in which one beam is a control beam, and another one is with special confinement reinforcement. The rest of the two beams are strengthened with the GFRP sheets in standard control beam and special confinement reinforcement beam under static or monotonic loading under three points, and the corresponding behavior is determined. The behavior of the RC Deep beams, such as load-carrying capacity, first crack load, load-deflection behavior, crack patterns, and stress vs. strains, are determined. The analysis of the reinforced concrete deep beams was done using the finite element software called ANSYS. Additionally, this article provides preliminary support for proposing a novel shear strengthening technique during the member’s design. In the finite element simulations, the proposed deep beams have been modeled and analyzed using the finite element software, ANSYS, and the results are compared with experimental work.
