The main purpose of the seismic design of structures is to have a resilient lateral system with the highest hardness, ultimate strength and ductility. Two types of the most efficient, most recent, most important and most expensive of these systems are steel shear walls and eccentric brace. In this research, models 5, 10 and 15 with dual steel frame systems and reinforced steel shear walls Braces and pendulums are observed. In such structural systems, the combination of two systems, both of which has a high degree of stiffness, and the addition of these systems to steelmoment frames, increases the stiffness of the upper floors. Therefore, In order to reduce the amount of this hardness, it is necessary to remove any steel shear wall reinforcement systems the end offloors in each of the ABAQUS finite element software studied. Then, by performing static nonlinear analyzes, we examine the results. The results of the analysis show that by removing eccentric braces of the steel shear wall are flowing, and removing the steel shear wall in some of these models is not possible and removing those eccentric brace, as well as parts of the steel moment frames As a result, the role of a steel shear wall in such systems is more than a eccentric brace.
