In　order　to　combine　the　steel　plate　shear　wall　system　with　new　prefabricated　steel　structure　system,　a　discontinuous　cover-plate　connection　(DCPC)　was　proposed　for　a　prefabricated　steel　plate　shear　wall　with　a　beam-only-connected　infill　plate.The　structure　and　design　method　of　DCPC　was　studied.　The　static　loading　tests　and　finite　element　analyses　ware　carried　out　on　four　1/3　scale　specimens　that　were　designed　and　manufactured　by　changing　the　thickness　of　the　infill　plate,　the　number　of　the　connecting　bolts　and　the　friction　coefficient　of　the　contact　surface.　The　results　show　that　increasing　the　number　of　bolts　can　effectively　improve　the　slipping　load　and　the　initial　stiffness　of　the　specimens,　but　can　increase　the　loss　of　pre-tightening　force　on　bolts　and　the　residual　deformation　of　the　cover　plate　and　the　bottom　plate.　Larger　friction　coefficient　can　effectively　increase　the　ultimate　lateral　capacity　force　of　the　specimens,　but　have　little　effect　on　the　pre-tightening　force　of　bolts.　The　loss　of　pre-tightening　forceon　bolts　increases　with　the　increasing　of　width-thickness　ratio　and　the　effective　height-span　ratio　of　the　infill　plate.　The　tension　fields　of　the　infill　plates　are　fully　developed　before　failure,　the　displacement　ductility　coefficients　satisfies　the　seismic　design　requirements,　and　the　failure　of　specimens　belongs　to　the　ductile　failure.　DPCP　not　only　has　good　mechanical　properties,　but　also　is　easy　to　be　manufactured　and　assembled,　and　it　can　ensure　the　repairable　function　of　the　steel　plate　shear　wall　after　earthquake.　©　2018,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
