The purpose of this report is to determine the effectiveness of using shear walls with Moment-resisting frames by modeling two bare frame structures. The first model is a combination of bare frames and shear walls, and the second model is without shear walls, and analyzing them statically (LATERAL FORCE METHOD) and dynamically (RESPONSE SPECTRUM METHOD) using ETABS 2016 software, and comparing the results of base shear forces, displacements and vibration modes, in order to form a comprehensive understanding of the proper use of shear walls. The report raises critical questions regarding the key factors of resisting seismic forces on similar structures, where rigidity or ductility can play opposing roles in the overall structure resistance.
