This　paper　presents　an　experimental　investigation　on　the　shear　behavior　of　steel　and　Ultra-high　Performance　Concrete　(UHPC)　composite　slab　connected　by　different　connector　types　including　epoxy　resin　adhesive,　headed　stud,　and　their　hybrid.　Thirty-two　push-out　tests　were　conducted　and　the　failure　mode　and　load-slip　cure　of　specimens　were　tested.　The　influences　of　parameters　including　the　connector　type,　bonding　area,　number　of　headed　studs　and　loading　mode　on　the　shear　resistance　of　hybrid　connector　were　explored.　The　shear　transfer　mechanism,　composite　effect　and　shear　resistance　of　the　stud　and　epoxy　resin　adhesive　for　hybrid　connector　were　discussed.　The　epoxy　resin　adhesive　and　headed　studs　in　hybrid　connector　showed　steel　interface　debonding　and　stud　shrank　failures.　The　ratio　of　shear　resistance　for　studs　to　epoxy　resin　adhesives　exerted　a　great　influence　on　the　slip　performance　and　shear　resistance　of　hybrid　connector.　The　composite　effect　depends　on　whether　the　studs　bear　the　load　firstly.　An　equation　was　proposed　by　taking　factors　including　the　composite　effect　and　loading　mode.　The　predict　results　showed　high　correlation　with　the　experimental　ones.　©　2023　Institution　of　Structural　Engineers
