Shear walls are one of the most lateral- forces resistant systems which have been nicknamed "shear walls" due to their high shear force absorption. Bending deformation of these structures is noticeable which results in great tensions at the foot of the wall. These walls are divided into two groups of reinforced concrete and steel walls and their behavior are different from each other. Reinforced concrete shear walls have high out- of- plane stiffness which prevents them from buckling but steel shear walls have low out- of- plane stiffness and their behavior is affected by diagonal traction fields which results in shear capacity reduction. In order to prevent these walls from buckling, steel plates are connected to concrete panels by means of shear studs. Coupling of steel shear walls changes their behavior and steel plates reach their ultimate capacity. Therefore, in this study, nonlinear static behavior and seismic parameters of composite shear walls system have been investigated. At the beginning of the research, a sample of the laboratory model has been verified to ensure the modeling of the composite shear wall in the nonlinear behavior range. In the next study, a double-skinned steel frame system and five-story compound shear walls were designed in a panel based on a reasonable behavior coefficient. In ABAQUS software, non-linear static modeling and analysis was performed and seismic parameters This system has been calculated for its behavior coefficient and shape. The results of the seismic parameters derived from this model are in good agreement with previous studies.
