Composite shear wall consisting of steel sheet with reinforced concrete cover is one of the most common systems resistant to lateral loads in tall structures. The main purpose of this study is to investigation the effect of reinforced concrete cover, steel sheet thickness, door and window opening on the seismic behavior of steel frame with composite shear wall. For this purpose, in the present study, after validation of numerical modeling, 19 specimens of composite steel shear wall with a height of 3.2m and a span length of 5m are modeled. The results of this study show that the utimate strength, stiffness, dissipated energy and ductility in the model with reinforced concrete cover without opening and with a steel sheet with a thickness of 15 mm, respectively 12.24, 63.78, 7.82 and 4.37 times the reference model and in the same model without reinforced concrete cover, these values are 8, 41.61, 4.46 and 6.24 times the reference model, respectively. In other words, the reinforced concrete cover, due to the prevention of buckling of the steel sheet due to compressive force, has increased the utimate strength, dissipated energy and ductility. Also, in reinforced concrete cover, increasing the thickness of the steel sheet from 10 to 15 mm has little effect on the utimate strength.
