Abstract: This research investigates the impact of various slit configurations in diagonal braces of concentrically braced frames using nonlinear finite element analysis in Abaqus software. The primary objective of this study is to optimize the seismic performance of these systems by utilizing yielding dampers and modifying the geometry of slits in damper plates. Several structural models were subjected to cyclic loading, and key parameters such as ultimate strength, energy absorption, stress distribution, plastic strain, and hysteretic behavior were comprehensively analyzed. The results indicate that when the slits are uniformly distributed across the surface of the damper, the system effectively utilizes the plastic capacity of the plate and achieves higher energy dissipation. Changes in the shape and pattern of slits significantly affect the distribution of plastic strain, stress concentration, and the reduction of strength in the final cycles. Therefore, optimizing slit designs can effectively enhance the seismic performance of structures. This study provides recommendations for improving brace designs, making a significant contribution to the safety and efficiency of earthquake resistant structures.
