Shear　wall　with　CFST　columns　and　concealed　trusses　is　a　new　kind　of　shear　wall.　In　order　to　analyse　its　seismic　performance　and　seismic　mechanism,　experiments　were　carried　out　on　three　1/5　scale　high　shear　wall　models.　Based　on　the　experimental　research,　load-carrying　capacity,　ductility,　stiffness　and　its　attenuation,　process　hysteretic　property,　energy　dissipation　and　failure　phenomena　of　each　model　were　analyzed.　The　finite　element　analysis　was　done　by　using　ABAQUS.　The　results　show　that　the　shear　wall　with　CFST　columns　and　concealed　trusses　has　good　seismic　yielding　mechanism,　and　the　seismic　performance　are　obviously　improved　compared　to　the　normal　RC　shear　wall.
