The importance of study on seismic behavior of joints in precast RC shear wall structures was expounded and the progress of investigation on seismic behavior of joints in precast RC shear wall structures was introduced.The design code and design method of joints in precast RC shear wall structures at home and abroad were also summerized.It is concluded that horizontal joints and vertical joints are important parts of precast RC shear wall structures.Horizontal joints transfer vertical load

bear horizontal shear force.Vertical joints transfer shear force between the precast shear walls

and affect the structure deformation and structural energy dissipation capacity.It is suggested that more attention should be paid to the construction measure

connection method of vertical bars across horizontal joints and energy dissipation behavior of assembled vertical joints in future research work.
