Abstract: There is few research on the steel-concrete composite coupling beam in China and the related theory is deficient. There is a lack of specific calculation method and detail measures in the current related codes as well. The steel-concrete composite coupling beam research at home and abroad including experimental study, bearing capacity calculation and influence factors of mechanical behavior were reviewed and evaluated. Seismic performances of several typical coupling beams were compared and the existing problems in the research were pointed out as well as the research field that had not yet been covered. It can provide reference for further experimental study and design on the steel-concrete composite coupling beam.
Keywords: steel-concrete composite coupling beam; seismic performance; shear bearing capacity; ductility
