According　to　the　structural　design　in　a　project　in　Dalian,　experimental　study　on　seismic　behavior　of　composite　core　walls　with　steel　tube-reinforced　concrete　(STRC)　columns　were　carried　out.　Five　1/6　scale　composite　core　wall　specimens　with　different　steel　reinforced　details　in　the　walls　and　different　openings　on　the　walls　were　designed　and　tested　under　cyclic　loading.　Based　on　the　experiment,　hysteretic　property,　load-carrying　capacity,　ductility,　energy　dissipation　capacity　and　damage　characteristics　of　the　five　specimens　were　compared　and　analyzed.　The　results　show　that　the　core　walls　with　STRC　columns　have　good　seismic　behavior.　And　the　seismic　behavior　can　be　greatly　improved　by　setting　concealed　steel　trusses　in　the　walls.
