N2 - This study investigates the effect of different reinforcement designs on the seismic performance of RC columns with beam-column joints connected using grouted sleeves. Through finite element analysis using ABAQUS software, various reinforcement configurations were simulated and their seismic performance was evaluated. 3 reinforcement configurations were simulated and their seismic performance was evaluated through finite element analysis using ABAQUS software. The results showed that the use of grouted sleeve connections with additional installed reinforcement and composite hoop configurations were effective in improving the seismic performance of prefabricated columns with grouted sleeve beam-column connection nodes. The stiffness reduction and displacement ductility of the specimens were analyzed, and it was found that the longitudinal reinforcement diameter had a negligible effect on the stiffness reduction, while the use of composite hoops was more effective in improving the displacement ductility compared to parallel hoops. These findings help to understand the behavior of beam-column connections and provide a reference for the design of seismic-resistant structures and future research. © The Authors, published by EDP Sciences.
