In　order　to　study　the　seismic　behavior　before　and　after　damage　of　bottom　enhanced　composite　shear　wall　with　CFT　column　frame　and　concealed　reinforcement　bracing,　bottom　enhanced　and　normal　shear　wall　specimens　were　tested　under　low　cyclic　loading.　In　the　first　stage　test,　the　specimens　were　loaded　to　reach　1/50　drift　ratio　and　yielding　phenomenon　was　obvious.　After　the　first　stage　test　stopped　and　the　horizontal　displacement　was　unloaded　to　its　initial　status.　The　second　stage　test　was　conducted　under　low　cyclic　loading　until　the　specimens　were　seriously　damaged.　Failure　features,　hysteretic　behavior,　bearing　capacity,　stiffness　degradation,　ductility,　energy　dissipation　ability　and　strain　were　all　analyzed.　Simplified　bearing　capacity　calculation　formulas　were　presented.　Research　shows　that　when　the　concrete　wall　suffers　no　damage,　the　bottom　enhanced　composite　shear　wall　gets　slighter　damage　and　higher　bearing　capacity　by　8.6%　than　normal　composite　shear　wall,　but　the　other　behaviors　of　the　two　walls　are　close.　After　a　big　part　of　the　concrete　wall　is　damaged,　the　bottom　enhanced　composite　shear　wall　has　higher　residual　bearing　capacity,　larger　deformation　capacity　and　stronger　energy　dissipating　capacity　than　the　normal　one.　Thus,　seismic　performance　degradation　speed　of　the　bottom　enhanced　shear　wall　is　relatively　low　and　the　anti-collapse　property　is　good.　The　presented　bearing　capacity　calculation　formula　can　well　estimate　the　bearing　capacity.　©,　2015,　Science　Press.　All　right　reserved.
