Due to its advantages over other earthquake-resistant systems, the use of a concentrically braced frame (CBF) has attracted the interest of researchers in recent years. As compared to other systems, it has several advantages, including abundance, high ductility, good hysteretic behavior and energy absorption capacity, high stiffness, and economic advantages. Buckling-Restrained Braced Frame (BRBF) is one of the new types of concentric braced frames that have been developed in recent years. These frames have high lateral stiffness and an outstanding ability to simultaneously hold earthquakes in energy dissipation features because of the prevention buckling brace. In this paper, the effect of different cross sections of BRBF such as circular, rectangular, diamond, elliptic, and octagon on ductility, resistance, and flexibility coefficient have been investigated by finite element method with ABAQUS software. The results show that the application of BRBF with oval and diamond cross sections for concentric braced frames against lateral loads can be used.
