The　ductility　of　reinforced　concrete　structures　is　often　determined　by　the　ductility　of　post-yield　deformed　rebar.　However,　to　date,　few　studies　have　been　conducted　on　the　bond　behavior　of　post-yield　deformed　rebars　embedded　in　ultra-high　performance　concrete　(UHPC).　Therefore,　a　pull-out　test　was　conducted　to　investigate　the　effects　of　the　cover,　embedded　length,　and　steel　fiber　on　the　bond　behaviors　between　UHPC,　and　pre-　and　post-yield　deformed　rebars.　The　test　results　showed　that　a　50%　increase　in　the　bond　strength　could　be　obtained　when　the　cover　was　increased　from　1d　to　2d,　where　d　is　the　diameter　of　the　deformed　rebar.　As　the　anchorage　length　was　increased　from　2.5d　to　5d,　the　bond　strength　decreased　by　approximately　50%.　Meanwhile,　the　bond　strength　increased　by　126%　with　an　increase　in　steel　fiber　content　from　0　to　2%.　To　predict　the　bond　strength　of　the　pre-　and　post-yield　deformed　rebar　embedded　in　UHPC,　a　modified　thick-walled　cylinder　model　was　proposed.　Subsequently,　the　distribution　of　the　bond　stress　along　the　embedded　length　was　revealed,　and　the　position　function　was　provided.　Finally,　the　bond　stress–slip　model　including　the　anchorage　position　function　provides　an　insight　into　the　bond　stress　between　UHPC　and　deformed　rebars.　©　2022　Elsevier　Ltd
