Experimental study on Bond slip relationship of Steel sleeve

The assembled concrete structure is usually connected with the steel bar through the sleeve. In order to realize the optimum design of sleeve structure and develop new sleeve, the author put forward a new test method, and made 18 specimens for uniaxial tensile test. Study the influence of the strength of grouting material, diameter of reinforcing steel bar on bond slip relationship between steel bar and grouting material and its failure characteristics by experimental research. This result suggests that with the increase of age, the bond strength between steel bar and grouting material is increasing gradually, the increase speed gradually slowed down after 20 days. For CT20H sleeve, with the increase of the diameter of reinforcement, the bond strength between reinforcement and grouting material increased gradually. Conclusion: In the optimization design of the sleeve, under the premise of ensuring the smooth injection of grouting material and be convenient for the positioning of the reinforced members, reducing the inner diameter of the sleeve can improve the bond strength between reinforcement and grouting material.
Key words: Assembled concrete structure / sleeve / bond slip / Constitutive relation
