A new type of composite shear wall with double steel plates and infill concrete with stiffeners was proposed. Quasi-static test on five specimens were conducted to investigate the influence of the axial force ratio and shear-span ratio on the seismic performance, including the failure mode, the hysteretic response, the deformability and energy dissipation. The results indicated that the composite shear wall with double steel plates and infill concrete with stiffeners shown good seismic performance of the specimens. The average values of the yield drift angle and ultimate drift angle for the five tests walls were 1/114 and 1/48, respectively. The bearing capacity of the specimens increased with the increase of the axial force ratio, but the seismic behavior decreased. With decreasing shear-span ratio, the bearing capacity and stiffness of the specimens rapidly increased, and the seismic performance was not significantly affected by the shear-span ratio. A finite element model was developed by using the ABAQUS software to simulate the performance of this type of composite shear wall, and the accuracy of the model was validated by comparing the calculated results with the experimental results.
