Abstract:Hybrid structures  are often used in super highrise buildings.The characteristics and the applications in China and overseas of different hybrid structures are introduced.The merits and demerits and seismic behavior about the hybrid structures of steel framereinforced concrete core wall and steel reinforced concrete framereinforced concrete core wall which are often applied in China are analyzed.On the basis of hybrid structures tests  and the applications in China and overseas，considering seismic factors，the applicability of hybrid structures in different seismic fortification intensity area and the problems needed to research in the future are put forward.
Keywords:hybrid structures；steel frame RC core wall;SRC  frameRC core wall; seismic behavior
