## 1 Introduction
This advanced brace system is engineered to restore the pre-seismic configuration of a structure after a seismic event, thereby mitigating the accumulation of permanent deformations and enhancing post-earthquake functionality. Integrating advanced computational models with emerging retrofit technologies such as the SCED system represents a promising pathway for advancing the seismic resilience of RC structures. The fiber-based FE approach, when combined with high-fidelity material models and refined discretization techniques, can accurately predict the behavior of RC frames retrofitted with innovative energy dissipation devices. For instance, the simulation frameworks discussed by [PERSON] and [PERSON] (2017) have underscored the importance of capturing localized damage phenomena, such as bond-slip and cracking in beam-column joints, which are critical in determining the overall hysteretic performance of a structure. Moreover, experimental validations conducted by [PERSON] et al. (2018) have provided empirical evidence that reinforces the potential of advanced computational models to predict the complex interactions between traditional BRBs and novel systems such as SCED. Such studies highlight the synergies between simulation and experimentation, establishing a feedback loop that continuously refines our understanding of seismic performance. The integration of these advanced computational techniques and innovative retrofit solutions is not merely an academic exercise but a pragmatic necessity in the face of escalating seismic hazards. Modern seismic design codes, while progressively incorporating computational insights, still leave significant room for improvement in their treatment of RC joints and energy dissipation mechanisms. In this context, the dual approach of employing robust numerical models alongside cutting-edge experimental research offers a holistic perspective that can inform the next generation of design standards. By bridging the gap between theoretical predictions and real-world behavior, these methodologies provide engineers with a more reliable basis for designing structures that can withstand severe seismic events with minimal damage. Furthermore, the incorporation of self-centering mechanisms, as embodied by the SCED system, represents a paradigm shift in seismic retrofitting strategies. Unlike conventional BRBs that primarily focus on dissipating energy through plastic deformations, SCED systems are engineered to combine energy dissipation with an inherent capacity for self-recovery. This dual functionality not only curtails the propagation of damage during an earthquake but also expedites the restoration process post-event, thereby reducing the downtime and repair costs associated with seismic retrofits. The promising results reported by [PERSON] et al. (2018) provide compelling evidence that SCED systems could redefine the standards for seismic retrofitting in RC structures, particularly when integrated within a computational framework that rigorously assesses their performance. This study, therefore, seeks to extend the state-of-the-art by bridging these perspectives, ultimately contributing to the development of safer, more resilient structures in seismically active regions. Joint failures can manifest as shear, flexural, or bond failures, each significantly undermining structural integrity. Analyzing these modes is critical for designing resilient RC frames, especially with enhancements such as buckling-restrained braces to improve performance under various loads. The primary failure mode in non-ductile reinforced concrete joints is brittle shear failure within the joint core. As shown in Figure 1a, seismic lateral loads generate significant diagonal tensile and compressive stress in the joint panel. If the joint lacks adequate transverse reinforcement diagonal cracking can quickly develop, leading to internal fracturing and crushing.
