This study was conducted to determine an economically viable and workable method of bolting the longitudinal double angle to the web of the H-beam. Experiments and FEM analysis were conducted to demonstrate the effectiveness of the reinforcement method. Experiments and analysis demonstrated that the reinforced beams outperformed the standard H-shaped steel beams in terms of strength. It was also demonstrated that the specimen reinforced with the beam web retained its strength even when loaded to a large end rotation angle of approximately 6%, exceeding the yield flexural strength measured. It was determined that angle reinforcement could increase the strength by at least 14%. The experiment was simulated using finite element analysis, and the resulting stress distribution and equivalent plastic strain distribution confirmed that the web reinforcement angle contributed to the stiffness and strength of the structure.
