Abstract

Country of Iran due to the existence of numerous faults and stresses by the borders of the shell, has been witnessing the occurrence of many earthquakes throughout the year. Thus providing resistant systems for structural stability against lateral forces of the main concerns of civil engineering in the country. The lateral resistant systems, Eccentrically Brace frame model, which relying on the rotation of link beam causes the absorption of structural earthquake force, while the excessive rotation of the link beam region can weaken the structural performance level, and makes some significant cracks in the concrete slab. In the present study, a new model of eccentrically brace system equipped with a steel plate in the lower link beam, and the beam out of the links provided. Numerical modeling in Abaqus software and protocol load is applied based on the ATC-24. The results show that the optimal positioning of steel plates and insert its plates in the lower link beam and the beam out of the links cause improve the shear performance of the bracing system in the development Plastic hinges And increased Shear strength and ductility of the bracing model. Finally, the energy absorption by the models has a significant performance in comparison with the current model.
