Advances in Constructional Engineering

Masonry structures, due to their low tensile and shear strength and inadequate seismic performance, often require reinforcement. While fiber-reinforced composites (FRP) demonstrate extensive applications in masonry reinforcement owing to their multiple advantages, interface peeling remains a prominent issue during reinforcement processes, significantly impacting both reinforcement effectiveness and structural safety. This study focuses on establishing interface peeling criteria for FRP-reinforced masonry structures. Through comprehensive analysis of failure modes and influencing factors—including material properties, bonding performance, and stress states—we develop a comprehensive mathematical model for interface peeling criteria, which is subsequently validated and applied through case studies. The research findings provide critical guidance for FRP-reinforced masonry structure design, effectively enhancing structural reliability and durability. These advancements hold significant implications for ensuring masonry safety and advancing reinforcement technology development.
