Özet

This review explores the use of Fiber Reinforced Polymer (FRP) bars to reinforce concrete slab-column connections, highlighting their potential to extend service life, reduce maintenance costs, and improve life-cycle cost efficiency. FRP bars offer a more environmentally friendly alternative to traditional steel reinforcement. The shear behavior of reinforced concrete structural members, which depends on complex internal load-carrying mechanisms, remains an active area of research. This article provides a comprehensive overview of the punching shear strength and behavior of FRP-reinforced concrete (FRP-RC) slab-column connections, both with and without FRP stirrups for shear reinforcement. It examines the mechanisms of punching shear in FRP-RC slab-column connections and reviews existing codes, proposed or modified models, and machine learning approaches for predicting the punching shear strength of these connections.
