In order to strengthen the seismic performance of double steel concrete combined shear wall, the number of the type steel (m=2,4,6), type steel size (I), type steel strength (Q235, Q345) (fp), steel plate strength (Q235, Q345) (fs), axial pressure ratio (n=0.4,0.5,0.7) were utilized as the main parameters. Nine double steel concrete combined shear walls were designed and its finite element model was established using ABAQUS software and validated with similar double steel concrete combined shear walls. The numerical results were compared with the test results o verify the rationality of the finite element model. Based on the verification results, the parameter analysis of 9 double steel concrete combined shear walls were conducted to study the main parameters affecting the seismic performance of reinforced double steel concrete. The results show that the bottom strengthening test piece has been improved in the load-carrying capacity, ductility, plastic degeneration capacity, stiffness degradation and energy consumption capacity. When the axial pressure ratios are 0.4 and 0.5, the ductility is close, whereas the ductility decreases when the axial pressure ratio reaches 0.7; When the axial pressure ratio is 0.5, the load-carrying capacity gradually increases with the increase of the number of the type steel. Increasing the strengths of the steel plate and type steel can significantly increase the ductility, initial stiffness and energy consumption and improve the seismic performance.
