Abstract
- Half-Grouted Sleeve Connection (HGSC) is extensively applied in the Prefabricated Concrete (PC) structures. The performance of the PC structures after fire has become an interesting research topic. However, the post-fire mechanical behaviors of the HGSC are still an issue that needs to be studied in depth. The experimental results of twelve HGSC specimens with concrete cover under static tension after 25 °C to 600 °C are presented in this paper. In the experiments, the post-fire HGSCs' failure mode is just rebar tension fracture, not bonding failure. The properties, such as strength, elongation, ductility, and elastic modulus were analyzed, and the failure mechanism, elongation and bonding slip, influence of concrete cover, bonding behaviour of HGSC after high temperature were discussed. It was found that some post-fire tensile properties of the HGSC were obviously affected by the peak temperature and the concrete cover.
