In order to study the bonding performance of adhesive reinforcement of fire-injured concrete,a large numbers of shear experiments on Z-shape bonding specimens based on injured concrete subjected to elevated temperature were done.Shear slipping curves were measured under several circumstances such as different temperature,different cooling ways and different interfacial roughness.At same time,the corresponding calculation formulas are deduced and the feature of shear slipping curve is also generalized.The study will provide reference for numerical simulating calculation of bonding reinforcement.
