Abstract

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.

Abstract

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.
