Abstract
As the physical and mechanical properties and surface shape of FRP(Fiber Reinforced Polymer) bars are quite different from those of steel bars, the bonding properties of FRP bars and concrete are lower than that of steel bars. How to effectively improve the bonding performance between FRP bars and concrete is a hot issue for scholars at home and abroad. The precondition of combining FRP bars with concrete is to ensure the cooperation between FRP bars and concrete under the action of external load. The bonding performance between FRP bars and concrete is one of the key technologies for designing, applying and popularizing this kind of structure. In this paper, based on a large amount of researches at home and abroad, the center pull test is carried out, and the adhesion mechanism, failure mechanism, influence factors of bond strength and slippage behavior between fiber reinforced polymer and concrete are studied through experiments.
