This paper addresses the seismic behavior of coupling beams with headed reinforcing bars in coupled shear wall system. Test variable included the replacement ratios of headed reinforcing bars. The results show that Specimen HB 50 exhibits a better stable behavior in comparison with Specimens Specimen CON and Specimen HB 30. Test results showed that the amount of diagonal reinforcing bars in the coupling beam may be reduced when headed reinforcing bars are utilized.

Coupling beams of coupled shear wall system in seismic regions are required to have high load resisting capacity and excellent ductility and energy-dissipation capacity. To achieve this goal, the concept of steel-concrete composite coupling beam is proposed. The steel-concrete composite coupling beam is a new form and worthwhile to research and promote. Further, it is a new direction for the future development of the coupling beam. But there is a lack of specific calculation method and constructional measures in the current related codes. In this paper, the review of available literatures is made including the experimental study and influence factors of mechanical behavior. It works that have not yet been covered after summarizing each research methods and research contents, which will provide scientific reference material for the intensive research on steel-concrete composite coupling beam.
