A　new　composite　shear　wall　with　concealed　steel　truss　was　put　forward.　It　included　two　kinds　of　composition.　One　was　composition　of　steel　truss　and　RC　shear　wall,　the　other　is　composition　of　profiled　steel　and　concrete.　In　order　to　compare　the　seismic　performance　of　shear　walls　with　concealed　steel　truss,　normal　shear　wall　and　steel　truss,　experimental　study　on　seismic　behavior　of　three　1/3　scale　specimens,　including　a　normal　shear　wall,　a　shear　wall　with　concealed　steel　truss　and　a　steel　truss,　were　carried　out　based　upon　the　experimental　study,　the　bearing　capacity,　hysteretic　property,　energy　dissipation　and　failure　mode　of　the　specimens　were　contrastively　analyzed.　The　experimental　results　show　that　the　seismic　bearing　capability　and　energy　dissipation　capacity　of　shear　wall　with　concealed　steel　truss　excelled　the　total　of　normal　shear　wall　and　steel　truss.
