The　combination　of　a　concrete-filled　steel　tube　(CFST)　column　and　reinforced　concrete　(RC)　beam　produces　a　composite　structural　system　that　affords　good　structural　performance,　functionality,　and　workability.　The　effective　transmission　of　moments　and　shear　forces　from　the　beam　to　the　column　is　key　to　the　full　exploitation　of　the　structural　performance.　The　studs　of　the　composite　beam　transfer　the　interfacial　shear　force　between　the　steel　beam　and　the　concrete　slab,　with　the　web　bearing　most　of　the　vertical　shear　force　of　the　steel　beam.　In　this　study,　the　studs　and　vertical　steel　plate　were　welded　to　facilitate　the　transfer　of　the　interfacial　shear　force　between　the　RC　beam　and　CFST　column.　Six　groups　of　a　total　of　18　specimens　were　used　to　investigate　the　shear　transfer　mechanism　and　failure　mode　of　the　plate-studs　connection,　which　was　confirmed　to　effectively　transmit　the　shear　forces　between　the　beam　and　column.　The　results　of　theoretical　calculations　were　also　observed　to　be　in　good　agreement　with　the　experimental　measurements.
