RC　shear　wall　with　STRC　(steel　tube-reinforced　concrete)　columns　and　embedded　steel　plate　has　been　proposed　and　used　in　the　project　of　an　International　Conference　Center.　In　order　to　ascertain　the　seismic　performance　of　this　kind　of　composite　shear　walls　with　different　openings　in　the　practical　engineering,　four　1/7　scale　specimens　with　shear　span　ration　2.0　were　tested　under　low-frequency　cyclic　loading.　The　load-carrying　capacity,　ductility,　stiffness　and　its　attenuation,　hysteretic　property,　energy　dissipation　capacity　and　failure　mode　of　the　specimens　were　analyzed.　The　effect　of　the　embedded　steel　plate　and　the　concealed　steel　trusses　on　the　seismic　performance　of　the　walls　was　studied.　The　results　show　that　the　ductility　and　load-carrying　capacity　of　RC　shear　wall　are　improved　greatly　by　setting　the　embedded　steel　plate　or　concealed　steel　trusses　in　the　wall;　The　embedded　steel　plate　and　the　concrete　work　very　well　through　the　stud　connectors　welded　on　the　steel　plate　and　the　tie　bars　inserted　in　the　walls;　The　STRC　columns　have　the　advantage　of　higher　load-carrying　capacity,　not　easy　to　crack　and　better　ductility;　The　new　composite　shear　wall　has　good　seismic　performance　and　important　practical　value.　It　is　suitable　for　large　and　complex　application　of　high-rise　buildings　in　the　seismic　regions.
