Shear　wall　with　concrete　filled　round　steel　tube　columns　and　concealed　bracing　is　presented.　This　new　composite　shear　wall　consists　of　two　kinds　of　composition.　One　is　composition　of　two　bearing　systems,　including　concrete　filled　steel　tube　frame,　steel　truss　and　shear　wall,　the　other　is　composition　of　two　materials,　including　steel　and　concrete.　So　it　is　a　multiple　composite　shear　wall.　The　experiment　was　carried　out　on　the　seismic　behavior　of　three　1/5　scale　mid-rise　shear　walls.　Based　on　the　experimental　study,　the　stiffness　and　its　attenuation,　bearing　capacity,　ductility,　hysteretic　property,　energy　dissipation　and　failure　phenomena　of　each　shear　wall　are　contrastively　analyzed.　The　formulas　of　bearing　capacity　and　stiffness　are　established.　The　results　obtained　from　the　formulas　and　those　from　experiment　are　in　good　agreement.　The　results　show　that　the　seismic　behavior　of　shear　wall　with　concrete　filled　round　steel　tube　columns　and　concealed　bracing　is　improved　evidently　compared　with　traditional　reinforced　concrete　shear　wall　in　high　axial-load　ratio.
