     in recent decades, steel plate shear wall (spsw) and concrete stiffened steel plate shear wall (cspsw) owing to their lateral stiffness, shear capacity, and ductility are considered as proper lateral-load resisting systems. in spsw system, infill steel plate buckles in compression field and the system carries lateral load by developing diagonal tension field; on the contrary, in cspsw due to the introduction of reinforced concrete panel, buckling of the infill steel plate is prevented. therefore, the cspsw resists shear forces by pure shear yield of the infill steel plate which is markedly higher. in this study, 16 one-story one-bay cspsws, with different infill steel plate thicknesses and practical aspect ratios, are designed in accordance with aisc seismic provision. this paper investigates nonlinear behaviour of cspsw and its corresponding spsw in order to grasp general behaviour and characteristic of cspsw. finite element code is developed by the authors and the nonlinear pushover analysis results depict that the complex behaviour of cspsw can be predicted. in addition, cspsw provides considerably higher shear capacity and greater initial elastic stiffness. it is worth mentioning that in cspsw, the infill composite wall-the steel plate and the reinforced concrete panel- resists lateral load up to a drift of 1.2~1.4 and after that shear capacity of frame becomes dominant. based on obtained results, ultimate strength and ductility of cspsw is noticeably greater than spsw.
