Advancements in construction materials have been a subject of considerable interest, with a particular focus on the use of carbon fiber-reinforced polymers (CFRP) as a means of enhancing the structural performance of various structures when utilized in an optimal manner. The objective of this research is to design and analyze reinforced concrete beam sections that incorporate concrete, steel, CFRP strips, and metal tubes. The study is contingent upon the high compressive strength of concrete confined within metal tubes and the tensile strength of CFRP strips. Concurrently, transverse and longitudinal reinforcement contribute to shear and flexural resistance. A total of twelve beam models were subjected to analysis, including three conventional reinforced concrete beams and nine composite sections that incorporated CFRP and metal tubes. The findings indicated a substantial enhancement in moment capacity, with the utilization of CFRP resulting in an average increase of 82.76%, metal tubes leading to an increase of 628.27%, and the combination of both contributing to an average increase of 791.3%. The study underscores the efficacy of these techniques in the design and strengthening phases, providing pragmatic guidelines for prospective applications.
