EVALUATION OF SEISMIC BEHAVIOR IMPROVEMENT IN RC MRF FRAMES RETROFITTED BY CONTROLLED ROCKING WALL SYSTEMS

Using rocking wall systems in reinforced concrete structures is a recent technique to improve their seismic behavior. In this paper reinforced concrete frame (MRF) with intermediate ductility, reinforced concrete frame with shear wall (RCSW), reinforced concrete frame with controlled rocking wall (RCRW) are compared with each other using push over analysis. Simulation and numerical analysis was performed with OpenSees software. The results show that plastic hinge formation and inter-story drifts are well distributed in the structure with rocking wall system in comparison with the other systems. Meanwhile, energy dissipation and ductility is increased in RCRW frames
