Abstract

The chapter delves into the bond behavior of CFRP/concrete joints subjected to fatigue loading, a critical aspect of structural reinforcement. It begins with an introduction to CFRP reinforcement technology and its advantages over traditional steel reinforcement. The experimental program involves a single-lap shear test to evaluate the bond performance under static and fatigue loading conditions. The study meticulously examines the failure modes, strain profiles, and load-slip responses of the specimens, revealing a progressive loss of interfacial bond stiffness. Notably, the chapter introduces a three-stage linear damage model to quantify the fatigue damage evolution, providing a robust framework for understanding and predicting the deterioration of CFRP-concrete interfaces. The findings offer crucial insights into the durability and performance of these joints under cyclic loading, making it a valuable resource for professionals in the field of structural engineering and materials science.
