Abstract

On the basis of tests for sixteen different specimens of composite concrete and doublesteel plate shear walls with binding bars, the failure modes of specimens with different aspect ratios, axial compression ratios and distances between binding bars were observed, and some valuable results were obtained for the specimens hysteretic loops, forcebearing capacity，skeleton curves and displacement ductility．The tested specimens aseismic parameters were compared with those of the traditional reinforced concrete walls using numerical analysis. The results indicated that the composite shear walls have better aseismic performances. Simultaneously the elastic-plastic time history analyses under different earthquake levels were conducted for both composite shear wall structural systems and traditional reinforced concrete shear wall systems with ABAQUS to compare their drift ratio and components plastic energy dissipation. The results demonstrated that the composite shear wall systems drift ratio and plastic energy dissipation are significantly reduced, and the energy dissipation capability of connected beams increases; the aseismic behavior of composite shear wall structure systems is better than that of traditional shear wall systems. 
