Aiming at the defects of reinforced concrete shear wall that the seismic behavior is insufficient

this paper sets SRC specially-shaped columns at the edge of RC shear wall

and puts forward a new mixed structure.In order to verify the seismic properties of shear wall with SRC specially-shaped cross columns frame

this paper conducts pushover analysis and hysteretic analysis on the basis of shell element and fiber element in open system Opensees.The RC shear wall adopts ShellMITC4 element

and the SRC specially-shaped columns adopt dispBeam-Column element.They are connected by zerolength element.The model is on a scale of 1∶2.5.Pushover curves

shears borne by columns and shear wall

hysteretic curves and equivalent damping ratio of specimens are obtained under different axial compression ratio.The study results show that the two component can form a whole

RC shear wall bears most shears

compared with RC shear wall.The ductility

maximum shear

and energy dissipation capacity of the mixed structure are improved in different degrees.With the axial compression ratio increase

the ratio of the improvement gradually decreases.The new structure can improve seismic behavior effectively under earthquake.
