摘要：

Eight HTRB600E steel sleeve grouting joint specimens filled with ultra-high performance concrete (UHPC) grouting material were fabricated for monotonic tensile testing. The effects of the grouting material mixing ratio and steel bar anchorage length on the mechanical properties of the connector joint specimens were investigated. The failure modes included rebar tensile fracture and rebar slip failure. The flexural performance, compressive performance and residual displacement of UHPC grouting material were significantly improved with the addition of steel fiber. However, the difficulty of grouting work increased with the addition of steel fiber. Increasing the anchorage length of rebar can significantly enhance the specimen bearing capacity but reduce the average bond strength. When UHPC is used as the grouting material, the recom-mended anchorage length of HTRB600E steel is at least 7d. As demonstrated by the test results, for the simulation of steel sleeve grouting joint monotonic tensile tests, an effective finite element (FE) model was established in ABAQUS.
