This paper provides a comprehensive review of the state-of-the-art techniques for enhancing the seismic performance of beam-column joints through retrofitting, focusing particularly on the use of Glass Fiber Reinforced Polymer (GFRP) and Near-Surface Mounted (NSM) technique. Beam-column joints are critical components in reinforced concrete structures, prone to damage and failure during seismic events. Retrofitting strategies using GFRP and NSM techniques have gained significant attention due to their effectiveness in improving the seismic resistance of existing structures. This review explores the key principles, design considerations, and performance enhancements achieved through GFRP and NSM retrofitting methods. Additionally, it discusses recent advancements, challenges, and future directions in the field of retrofitting beam-column joints for seismic resilience.
