Steel composite shear wall system is consisted of steel plates, I shape beams and columns, and composite columns with infill concrete,  . In order to evaluate and improve the behavior of this innovated system, it is necessary to investigate the effect of these parameters on reversed cyclic response. In this paper, a tested steel composite shear wall subjected to cyclic load was modeled. The model was verified using nonlinear dynamic analysis. Several models, in which the effective parameters were varied, have been nonlinear analyzed under dynamic reversed cyclic loads. Results show that by varying these parameters, the general shape of hysteresis loops remained unchanged and the shear behavior with large capability of energy dissipation, were noted. The dissipated energy and dynamic strength increased 10 % to 31% and 20%, respectively, as these parameters changed, where the maximum increase was related to increase of steel plate thickness. Increase of concrete strength to more than 20MPa did not significant effect on ductility, thus using concrete with compressive strength more than 20MPa is not recommended. Based on the results, the ductility ratio of  is determined and recommended.
