Replacing　concrete　with　engineering　cementitious　composite　(ECC)　can　improve　continuous　collapse　resistance　of　structure　under　accidental　load,　but　bond-slip　failure　may　occur　between　rebars　and　ECC　during　catenary　large　deformation　stage.　Here,　based　on　split　Hopkinson　pressure　bar　(SHPB)　testing　device,　dynamic　bond-slip　performance　tests　between　rebars　and　ECC　were　conducted.　Effects　of　ECC　strength　grade,　strain　rate,　and　rebar　diameter　on　the　ultimate　bond　strength,　stiffness　and　slip　amount　were　analyzed　to　obtain　the　average　bond-slip　curve　between　rebars　and　ECC　under　high　strain　rate　load　and　their　bond-slip　failure　mode.　Compared　with　static　bond-slip　tests,　the　dynamic　bond　dynamic　increase　factor　(DIF)　was　obtained.　Furthermore,　using　the　method　of　sticking　strain　gauges　inside　rebar　groove,　distribution　laws　of　bond　stress　and　relative　slip　at　different　anchoring　positions　were　obtained　and　the　bond　position　function　was　proposed.　Finally,　based　on　test　results,　the　average　bond-slip　constitutive　relation　between　rebars　and　ECC　was　obtained,　this　relation　was　then　multiplied　by　the　bond　position　function　to　obtain　the　dynamic　bond-slip　constitutive　relation　considering　effects　of　anchor　position,　and　provide　test　basis　and　theoretical　reference　for　design　and　finite　element　analysis　of　ECC　structural　components.　©　2024　Chinese　Vibration　Engineering　Society.　All　rights　reserved.
