This paper presents structural performance of composite beams which consist of steel reinforced concrete in both ends of the beam and reinforced concrete with diagonal reinforcements in the middle of beam. The experiment for the composite beam specimens, for which the parameters were the form of bar arrangement and shear span to beam depth ratio, were carried out with the object of investigating structural performance. The results were as follow: Yield hinges were formed at both ends of the composite beam. Its hysteresis performance was becoming the same as that of universal steel reinforced concrete when both adequate arrangement of additional bars and the closer spacing of the stirrups at the position where the form of reinforcement changed were provided. Because of application of additional bars anchored suitably at steel reinforced concrete region, the composite beam exhibited flexural strength higher than the calculated value from the general superposed strength method.
