In the recent years, composite beam is now being frequently used not only in reduction of the story height but also saving material quantity. There has been heightened interest in composite beam. In this study, new composite beam was proposed, which composed of H-section and U-section members. Angles were used for shear connectors for composite action. In order to investigate the performance of the suggested composite beam, test programs were carried out to evaluate the composite beam's structural behavior and effectiveness as conducted experiments consist of push-out tests, beam flexural tests and beam-column connection tests.
