This　paper　presents　an　investigation　of　the　feasibility　of　self-piercing　rivet　(SPR)　technology　for　use　in　cold-formed　steel　(CFS)　structures.　The　mechanical　properties　of　the　joints,　floor　trusses　and　prefabricated　CFS　composite　floor　modules　connected　by　SPR　and　self-drilling　screws　(SDSs)　were　compared.　The　failure　mode,　bearing　capacity,　stiffness,　ductility,　ultimate　deformation　and　other　performance　of　CFS　specimens　connected　with　SDS　and　SPR　were　analyzed.　Considering　the　construction　method　of　CFS　structure　and　the　particularity　of　SPR　connection　technology,　the　construction　feasibility　of　SPR　connection　was　analyzed.　The　results　showed　that　under　the　same　condition,　the　stiffness　and　ductility　of　the　SPR　joint　specimens　are　significantly　better　than　those　of　the　SDS　joint　specimens,　the　bearing　capacity　of　the　two　are　similar,　and　the　ultimate　mid-span　deflection　of　the　composite　floor　with　SPR　specimens　is　significantly　greater　than　that　with　SDS　specimens.　It　is　highly　feasible　to　use　the　SPR　connection　instead　of　the　SDS　connection　for　prefabricated　light　steel　floor　system　with　high　stiffness　requirements　(C)　2020　Elsevier　Ltd.　All　rights　reserved.
