One new design method that is currently under consideration by researchers is performance-based design (PBD). This method has been evaluated using different criteria and definitions. In the current study, the weight optimization problem is defined using PBD to consider more constraints than have been considered in other studies in this field. The problem has been formulated for eccentrically braced frame (EBF) structures. Thus far, weight optimization of EBFs using PBD has not been attempted. For this reason, the main objective has been to examine the possibility of optimizing the EBF weight based on PBD. A new method for modeling of the link beam has been used to evaluate its behavior. Structural analysis has been done using nonlinear static analysis (pushover). The performance of the proposed optimization process is demonstrated for the optimal design of two 2D EBF structures using four different metaheuristic algorithms.
