The　paper　examined　the　bond-slip　behaviour　of　steel　fibres　embedded　in　ultra-high-performance　concrete　(UHPC)　after　exposure　to　elevated　temperatures.　Different　types　of　steel　fibres　were　cast　into　the　halved　UHPC　dog-bone-shaped　samples,　including　straight　fibres,　three　types　of　hooked-end　fibres　and　corrugated　fibres.　The　bond　response　was　investigated　through　single　fibre　pull-out　tests　on　the　samples　unheated　and　heated　to　200,　400　and　600　°C.　In　addition,　the　effects　of　polypropylene　(PP)　fibre　addition　and　heating　rate　on　steel　fibre＇s　bond　behaviour　were　also　investigated.　The　results　revealed　an　increase　in　bond　strength　when　the　straight　and　hooked-end　fibre　samples　were　heated　to　200　°C,　while　the　bond　strength　of　the　corrugated　fibre　decreased　at　the　same　temperature.　Bond　strength　reductions　were　observed　at　higher　temperatures.　In　addition,　the　straight　fibres　led　to　the　lowest　pull-out　resistance　as　both　the　hooked-end　and　the　corrugated　fibres　significantly　enhanced　the　bond　strength.　With　the　hooked-end　or　corrugated　fibres,　the　failure　mode　gradually　shifted　from　pull-out　failure　to　fibre　rupture.　Besides,　adding　PP　fibres　increased　the　bond　strength　of　straight　fibres　at　400　°C　but　reduced　the　bond　strengths　of　hooked-end　fibres　at　ambient　and　high　temperatures.　High　heating　rate　also　led　to　a　greater　bond　strength　for　the　straight　fibres　at　200　°C　and　400　°C.　©　2023　Elsevier　Ltd
