In　order　to　improve　the　seismic　performance　of　RC　high-rise　shear　wall,　the　RC　high-rise　shear　wall　with　concealed　truss　was　brought　forward.　The　concealed　truss　included　steel　truss,　steel　bar　truss　and　the　composition　truss　of　shaped　steel　and　steel　bar.　This　new　shear　wall　was　a　double　composite　shear　wall,　viz.,　the　combination　of　truss　and　shear　wall　and　the　combination　of　steel　and　concrete.　The　experimental　study　was　carried　out　on　the　seismic　performance　of　six　1/3　scale　high-rise　shear　walls,　including　one　with　steel　frame,　four　with　different　style　concealed　trusses　as　well　as　a　normal　one.　The　load-carrying　capacity,　ductility,　stiffness　and　its　attenuation,　hysteretic　property,　energy　dissipation　and　failure　phenomena　of　each　specimen　were　contrastively　analyzed.　The　formulas　of　calculating　load-carrying　capacity　and　stiffness　were　established.　Some　suggestions　for　seismic　design　of　RC　high-rise　shear　wall　with　concealed　truss　were　put　forward.　The　results　obtained　from　formulas　and　experiments　were　in　good　agreement.　Experimental　results　showed　that,　compared　with　normal　RC　high-rise　shear　wall,　the　seismic　performance　of　the　RC　high-rise　shear　wall　with　steel　frame　and　concealed　truss　was　obviously　improved.
