This study was conducted to identify the structural performance of the opening in a location close to the support point in the perforated beam system of steel beams. In addition, structural performance was determined through experiments on reinforced openings using steel plates and square steel tube. In steel simple beams, the openings were more appropriate than the height(d) of the steel beam to be located close to the support point, half the height(d/2) of the steel beam. The reinforcement volume efficiency ratio is a comparison of reinforced load ratio and Reinforced volume ratio, this is an indicator that considers structural performance with an economic efficiency. The reinforcement volume efficiency ratio of square steel tube was greater than that of steel plate. Consequently, considering the economic feasibility along with the reinforcement performance, square steel is judged to be a more suitable reinforcement form for reinforcement of H-Shaped Steel Simple Beams with Web Openings than steel plates.
