To　study　the　seismic　behavior　and　post-earthquake　repairability　of　coupled　shear　wall　with　concrete　filled　steel　tube　(CFST)　frame　and　concealed　partitioned　steel　plates　(SPs),　three　1/5　scaled　coupled　shear　wall　specimens　were　designed　with　different　type　of　CFST　column　or　core　structure.　Low-cycle　reversed　loading　was　adopted　in　the　test.　The　test　contained　two　stages.　Load-carrying　capacity,　energy　dissipation,　ductility,　stiffness　and　failure　characteristic　of　the　specimens　were　compared　in　pre-repair　stages　and　post-repair　stages.　The　conclusions　are　drawn　that　the　core　structure　shows　a　good　ductile　yielding　mechanism.　The　cross-section　type　of　frame　has　an　obvious　effect　on　the　seismic　behavior　of　shear　wall.　After　damage　and　strengthening,　the　new　coupled　shear　wall　still　has　enough　seismic　capacity　and　good　energy　dissipation　capacity,　and　it　is　easy　to　be　repaired　after　earthquake.　Finite　element　analysis　software　ABAQUS　has　been　used　to　simulate　the　behavior　of　coupled　shear　wall.　Ultimate　strength　is　obtained　with　the　vibration　of　thickness　of　SPs.
