To　meet　the　increasing　demand　for　high　strength　and　non-combustible　shear　wall　systems　in　mid-rise　cold-formed　steel　(CFS)　constructions,　an　innovative　CFS　shear　wall　system　with　in-frame　corrugated　steel　sheathing　is　invented　and　investigated　in　this　paper　experimentally　and　numerically.　Bearing　wall　and　shear　wall　specimens　with　in-frame　corrugated　steel　sheathing　are　tested　under　combined　lateral　and　gravity　loading.　The　results　show　that　the　shear　strength　of　the　innovative　shear　wall　is　higher　than　currently　code　certified　shear　walls　in　AISI　S400　so　that　it　could　be　employed　for　mid-rise　buildings　in　areas　that　are　prone　to　high　seismic,　and　wind　loads　more　efficiently.　It　is　also　found　that　the　shear　strength　of　bearing　walls　is　approximately　one-third　of　the　shear　strength　of　shear　walls,　which　proves　that　bearing　walls　also　provide　significant　shear　resistance　in　a　structure.　To　evaluate　and　quantify　the　seismic　performance　factors　of　this　new　lateral　force-resisting　system,　nonlinear　static　and　dynamic　analyses　are　performed　on　6　building　archetypes　by　using　OpenSees　software　according　to　the　methodology　recommended　by　FEMA　P695.　The　seismic　performance　evaluation　results　verified　that　the　existing　seismic　performance　factors　used　for　light-framed　shear　wall　systems　with　flat　steel　sheets　can　also　be　used　for　the　innovative　cold-formed　steel　shear　wall　system.　©　2023　SSRC.　All　Rights　Reserved.
