To　enhance　the　seismic　performance　of　prefabricated　shear　walls　and　realize　structural　reparability　after　earthquake-induced　damage，a　repairable　steel-connection　precast　shear　wall（RS-PSW）is　proposed.　It　could　be　achieved　that　the　damage　to　the　structure　is　concentrated　on　the　steel　connection　by　replacing　the　vulnerable　bottom　area　of　shear　walls　with　steel-connection　area.　The　function　of　reparability　is　implemented　by　replacing　damaged　steel-connection　members　after　earthquakes.　The　ordinary　concrete　shear　wall（SW0），specimen　RS-PSW1（initial　loaded），and　specimen　RS-PSW2（loaded　after　seismic　damage）are　subjected　to　low　circumferential　reciprocal　loading　tests　to　compare　and　analyze　the　failure　modes，hysteretic　behavior，stiffness　and　bearing　capacity　degradation，energy　dissipation　and　seismic　damage　reparability　of　RS-PSW.　The　results　show　that　compared　with　SW0，RS-PSW1　exhibits　a　sharp　reduction　of　cracks　in　the　upper　precast　concrete　wall　when　the　displacement　angle　reached　1.43%，and　the　deformation　is　concentrated　in　the　steel-connection　area.　Compared　with　SW0，the　bearing　capacity　and　stiffness　of　repaired　specimen　RS-PSW2　have　slightly　decreased，but　the　ductility　and　energy　dissipation　have　greatly　improved，the　failure　displacement　angle　of　RS-PSW2　reaches　2.67%，which　is　66.7%　higher　than　SW0.　It　indicates　that　RS-PSW2　presents　a　better　deformation　capacity.　The　seismic　performance　indexes　of　specimen　RS-PSW2　under　reloading　are　basically　the　same　as　those　under　initial　loadign，which　verifies　that　RS-PSW　can　realize　the　repairable　function　of　earthquake-induced　damage，and　the　seismic　performance　of　the　structure　can　be　quickly　restored　by　replacing　the　damaged　steel　connectors.　©　2023　Nanjing　University　of　Aeronautics　an　Astronautics.　All　rights　reserved.
