Abstract: :The configuration of the steel reinforcement is investigated in this work in connection tothe flexural behavior of reinforced concrete beams(RC beams).Employing unique steel reinforcementconfigurations allowed for the investigation of the influence that the shape of the steel has on theparameters of the concrete beam, such as the cracking load, ultimate load, load-deflection curve , ductility, and energy absorption. Seven beams were manufactured in all, and they were divided into two groups: those that supported the concrete beams with curved steel bars, and those that usedtriangular steel reinforcement. Several bars of curved and triangle reinforcement were employed, withtwo, three, and five bars being utilized.The flexural behavior of reinforced concrete beams was foundto be affected by the presence of curved and triangular steel reinforcement, according to research. The curved steel reinforcement not only increased the flexural strength but also significantly enhancedthe ultimate load-bearing capacity. Additionally , the cracking strength was marginally increased asa result of the reinforcement. On the other hand, the cracking strength was significantly lower andthe final flexural strength was significantly higher for steel bars that were organized in a triangle .In contrast to the triangular form, which showed a decrease in the cracking load of 4.2%-7.1% andan increase in the ultimate load of 7.8%-8.15%, the cracking load increased from 5.7% to 8%, andthe ultimate load climbed from11.4% to 32%.Both of these changes were accomplished by increasingthe ultimate load.The ductility of the steel as well as its capacity to absorb energy were both enhancedby the modification of its configuration
