In　order　to　improve　the　defects　of　single　self-drilling　screw　connection　and　self-piercing　riveting　(SPR)　in　cold-formed　steel　structure,　this　paper　presented　a　screw-rivet　hybrid　connection　with　complementary　advantages.　Shear　tests　on　132　hybrid　connections　were　conducted.　The　differences　of　pure　screw　connection,　pure　SPR　and　hybrid　connection　were　compared　and　analyzed.　The　effects　of　sheet　thickness,　sheet　thickness　ratio　and　fastener　arrangement　on　shear　properties　and　failure　mechanism　were　studied.　The　applicability　of　the　existing　direct　summation　methods　was　also　investigated,　and　then　the　improved　calculation　method　of　shear　capacity　of　hybrid　connection　was　proposed.　The　results　show　that　hybrid　connection　could　fully　combine　the　advantages　of　screw　connection　and　SPR　by　effectively　improving　the　bearing　capacity,　stiffness　and　ductility　of　pure　screw　connection,　and　the　deformation　capacity　and　energy　dissipation　of　pure　SPR.　Sheet　thickness　and　sheet　thickness　ratio　are　key　factors　affecting　shear　properties　and　failure　modes,　respectively.　The　connection　arrangement　has　significant　influence　on　mechanical　properties　and　failure　mechanism.　Since　the　mechanical　mechanism　and　behavior　of　different　connections　vary　greatly,　the　existing　direct　summation　method　is　not　safe　for　the　calculation　of　bearing　capacity　of　hybrid　connection.　In　contrast,　based　on　the　reduction　method　of　capacity,　the　calculation　method　proposed　in　this　paper　for　shear　capacity　is　more　accurate,　which　could　not　only　consider　more　comprehensive　failure　mode　but　also　be　more　safe　and　reliable　in　design.　©　2020,　Editorial　Office　of　Journal　of　Building　Structures.　All　right　reserved.
