In　this　study,　an　attempt　was　made　to　study　the　bond-slip　performance　of　end-hook　and　half-hooked　steel　fibers　embedded　in　moderately　strength　SIFCON　matrix,　to　find　out　the　cause　of　excessive　mechanical　anchorage　and　to　further　optimize　the　bond-slip　equation　of　steel　fibers.　Used　end-hook　steel　fibers　with　embedded　depths　10　and　15　mm,　pullout　offset　angles　0°,　30°,　45°,　and　60°;　Half-hooked　steel　fiber　with　embedded　depths　10　and　15　mm,　end-hook　bending　angles　30°,　45°,　60°,　and　90°;　Novel　end-hook　and　novel　half-hooked　steel　fibers　with　end-hook　length　doubled,　which　were　subjected　to　a　static　pullout　test　at　a　rate　of　0.01　mm/s.　Experiments　showed　that　the　half-hooked　steel　fiber　took　the　best　end-hook　bending　angle　at　60°;　The　novel　end-hook　and　half-hooked　steel　fiber　had　a　good　bonded　performance.　The　single　steel　fiber　anchorage　performance　evaluation　index　K　was　proposed.　Through　experimental　phenomena,　data　analysis,　and　X-ray　flaw　detection,　the　existence　of　“local　damage”　was　proved.　Based　on　the　traditional　bond-slip　formulation,　a　new　bond-slip　formulation　for　moderately　strength　SIFCON　substrates　is　proposed　by　adding　a　plastic　hinge　in　the　“local　damage”　region.　By　comparing　the　old　and　new　equation,　it　was　found　that　the　calculation　error　of　the　maximum　pullout　load　of　end-hook　steel　fibers　was　reduced　by　3.77　times　and　that　the　calculation　error　of　the　maximum　pullout　load　of　half-hooked　steel　fibers　was　reduced　by　2.8　times,　and　the　calculation　equation　for　the　peak　load　of　secondary　reinforcement　of　half-hooked　steel　fiber　was　supplemented,　which　is　of　application　value　for　further　optimization　of　the　shape　of　steel　fibers.　©　2023　Elsevier　Ltd
