Reinforced concrete (RC) beam–column joints are among the most critical components governing the seismic performance, strength, and ductility of framed structures. Numerous post-earthquake investigations have revealed that inadequate joint detailing and insufficient confinement reinforcement frequently lead to brittle shear failures and significant structural damage. Over the past two decades, substantial research efforts have focused on improving joint performance through innovative reinforcement detailing, advanced construction materials, numerical modeling techniques, and data-driven design approaches. Despite these developments, existing design codes continue to rely on simplified assumptions regarding shear transfer mechanisms, reinforcement contribution, and confinement effects, resulting in conservative or sometimes inaccurate predictions of joint behavior. This paper presents a comprehensive review of recent advances in RC beam–column joint research, with particular emphasis on cross-tie reinforcement configurations, fiber-reinforced and ultra-high-performance concrete systems, sustainable concrete materials and finite element modeling techniques. The review critically evaluates current understanding of joint shear resistance mechanisms, ductility enhancement strategies, and the effectiveness of different reinforcement layouts under seismic loading conditions. Furthermore, the limitations of existing analytical models and international design provisions are examined in light of recent experimental and numerical findings. Research trends, emerging technologies, and future directions for code development are discussed. The study highlights the need for performance-based design methodologies that integrate advanced materials, optimized reinforcement detailing, and machine learning tools to achieve safer, more sustainable, and resilient reinforced concrete structures.
KEYWORDS
This review critically examined recent advancements in reinforced concrete beam–column joint research, focusing on reinforcement detailing, advanced materials, sustainable concrete technologies, numerical modeling approaches, and artificial intelligence applications. The review revealed that cross-tie reinforcement significantly improves joint confinement, shear resistance, and deformation capacity compared with conventional stirrup arrangements. Polygonal cross-ties, inclined reinforcement systems, and spiral confinement configurations consistently demonstrated superior structural performance. However, current international design codes do not adequately account for these improvements. The findings also indicate that advanced materials such as fiber-reinforced concrete, reactive powder concrete, and ultra-high-performance concrete can substantially enhance joint performance. Nevertheless, comprehensive investigations integrating these materials with innovative reinforcement layouts remain limited. From a sustainability perspective, research on geopolymer and recycled aggregate concrete beam–column joints is still at an early stage. More experimental and numerical studies are required to evaluate their seismic performance and long-term durability. Finite element modeling has become a powerful tool for understanding joint behavior; however, most studies rely on monotonic loading conditions and simplified material assumptions. Future research should emphasize cyclic loading simulations and realistic bond-slip modeling. Artificial intelligence and machine learning represent promising emerging technologies for structural design and performance prediction. The development of data-driven design models capable of incorporating reinforcement detailing effects, material properties, and loading conditions could significantly improve the accuracy of current design methodologies.
