Based　on　the　relevant　research　literature　and　the　existing　342　sets　of　self-drilling　screw　tensile　test　results,　the　research　status　of　the　pull-out　behavior　and　pull-over　behavior　of　self-drilling　screw　connection　in　cold-formed　steel　structure　were　summarized.　The　calculation　accuracy　and　applicability　of　self-drilling　screw　design　methods　in　Technical　Code　of　Cold-formed　Thin-walled　Steel　Structures(GB　50018-2002),　Technical　Code　of　Cold-formed　Steel　Structures　(Draft　for　Comments),　American　code　(AISI　S136-16),　Australian　code　(AS/NZS　4600:　2018),　British　code　(BS　5950-5-1998)　and　European　code　(BS　EN　1993-1-3:　2006)　were　compared　and　analyzed　in　this　paper.　Results　show　that　design　method　in　Technical　Code　of　Cold-formed　Steel　Structures　(Draft　for　Comments)　has　highest　accuracy　and　applicability.　For　550　grade　steel　plate　with　thickness　lower,　a　reduction　factor　of　0.8　on　the　tensile　capacity　is　needed.　For　medium　and　low　strength　steel　plate　with　thickness　more　than　2　mm,　design　value　by　Technical　Code　of　Cold-formed　Steel　Structures　(Draft　for　Comments)　is　uneconomical.　In　addition,　it　is　suggested　that　the　ratio　of　nominal　diameter　of　screw　to　plate　thickness　should　not　exceed　8　to　ensure　that　the　connection　performance　of　self-drilling　screw　and　steel　plate　can　be　better　exerted　when　the　maximum　pull-out　capacity　of　screw　joint　is　reached.　©　2022,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
