The　shear　wall　with　concrete　filled　steel　tube　(CFT)　columns　and　steel　plate　is　a　new　kind　of　composite　shear　wall.　In　order　to　know　its　seismic　performance　and　failure　mechanism,　six　1/5　scale　specimens　with　the　same　shear　span　ratio　1.5,　including　3　steel　plate　shear　walls　(SPSWs)　with　CFT　columns　and　3　reinforced　concrete　shear　walls　(RCSWs)　with　CFT　columns　and　embedded　steel　plate,　were　tested　under　cyclic　loading.　The　thickness　of　the　steel　plates　in　the　shear　walls　changed　from　2mm,　4mm　to　6mm.　Based　on　the　experiment,　the　load-carrying　capacity,　hysteresis　characteristics,　ductility,　stiffness　degradation,　energy　dissipation　and　damage　characteristics　of　the　specimens　were　analyzed.　Especially,　the　ratio　of　height　to　sectional　thickness　of　the　steel　plates　in　the　shear　wall　was　considered.　The　result　shows　that　both　the　SPSW　with　CFT　columns　and　the　RCSW　with　CFT　columns　and　embedded　steel　plate　have　good　seismic　performance　and　are　with　important　practical　engineering　value.
