Abstract
As a composite structure, the most important performance of the reinforced concrete structure is the bond behavior between them. Good bond behavior is the key to ensuring the service performance of reinforced concrete structures, which affects the performance of the structure at various stages in its life cycle. However, in the actual structural analysis, it is generally believed that the two do not produce relative slips, resulting in some differences between the analyzed structure and the actual engineering situation. At present, many scholars all over the world have used different test methods, comprehensively considered various factors affecting the bond behavior between deformed rebar and concrete, and obtained many conclusions. In this paper, based on the relevant research results of many scholars, starting from the bond mechanism, the experimental research method of the bond behavior, and the influencing factors of the bond behavior, a detailed review of the research status of the bonding performance of reinforced concrete is carried out. It is hoped that it can provide a reference to scholars that will study the bond behavior of reinforced concrete in the future.
