        abstract = {Eccentrically braced frames (EBFs) are commonly used in steel structures as lateral load-resisting systems. These systems are designed to undergo inelastic deformations during strong seismic events, allowing them to absorb and dissipate earthquake energy. Most seismic design codes account for this energy dissipation by introducing a strength reduction factor, which reduces the calculated earthquake loads to better reflect the actual behavior of structures under seismic forces. This reduction is achieved by dividing the base shear obtained from analysis by the strength reduction factor. The factor itself is influenced by three main components: ductility, over strength, and redundancy, which depend on both the structural system and the properties of the construction materials. In this study, a parametric analysis was conducted to determine the strength reduction factor values for eccentrically braced steel frames. Key parameters such as storey height, number of bays, length of the shear link, and location of the braced bay were varied across different 2D models. Both static analysis and response spectrum analysis were used to evaluate the strength reduction factor for each configuration. The results were then compared with values recommended in various design codes to assess the influence of the considered parameters on structural performance.},
