The　RC　short-pier　shear　wall　structure　is　a　new　type　of　structural　system　in　tall　residential　buildings.　It　has　been　applied　in　many　buildings　in　China,　but　its　seismic　performance　is　worse　than　that　of　normal　shear　wall　structures.　Therefore,　how　to　improve　its　seismic　performance　becomes　a　problem　which　has　been　paid　much　attention　by　engineers.　In　this　paper,　the　seismic　performance　of　short-pier　shear　walls　with　concealed　bracing　is　investigated.　An　experimental　study　of　four　1:3　scale　coupled　short-pier　shear　wall　specimens　has　been　carried　out,　two　of　which　were　normal　coupled　short-pier　shear　walls,　and　the　other　two　coupled　short-pier　shear　walls　with　concealed　bracing.　Based　upon　the　experimental　study,　the　effects　of　concealed　bracing　on　the　load-carrying　capacity,　stiffness,　ductility,　hysteretic　behavior,　energy　dissipation　and　failure　mechanism　of　shear　wall　are　discussed.　It　is　shown　that　the　seismic　performance　of　short-pier　shear　walls　is　greatly　improved　by　concealed　bracing.　Finally,　mechanical　models　for　calculating　the　load-carrying　capacity　of　the　shear　wall　are　proposed,　and　the　theoretical　results　agree　well　with　those　from　experiments.
