Shear　wall　with　single　row　of　steel　bars　is　suitable　for　low-rise　and　multistory　residential　structures.　Combined　with　assembled　construction　technology,　assembled　and　semi-assembled　shear　wall　with　single　row　of　steel　bars　is　presented.　Assembled　shear　wall　structure　consists　of　upper　precast　concrete　shear　wall　with　reserved　holes,　lower　precast　shear　wall　with　single　row　of　button-head　vertical　steel　bars　and　slurry　layer　between　them;　semi-assembled　shear　wall　structure　consists　of　these　three　parts　as　well　as　cast-in-place　concealed　columns　between　longitudinal　and　transversal　walls.　Button-head　steel　bars　extending　from　the　surface　of　lower　precast　shear　wall　could　be　anchored　in　reserved　holes　of　upper　precast　shear　wall,　with　high　strength　grouting　material　filling　the　holes.　To　evaluate　the　seismic　behavior　of　assembled　shear　wall　and　semi-assembled　shear　wall　with　single　row　of　steel　bars　and　the　application　effect　of　recycled　concrete　in　the　precast　shear　walls,　three　full-scale　I-shaped　recycled　concrete　shear　wall　specimens　are　tested　under　cyclic　reversed　loading,　one　is　assembled,　one　is　semi-assembled　and　the　other　cast-in-place.　Failure　character,　bearing　capacity,　stiffness,　energy　dissipation　and　shear　slip　are　compared,　results　show　that:　recycled　concrete　has　good　application　effect　in　the　precast　shear　wall;　seismic　performance　of　assembled　shear　wall　is　poor;　similar　to　the　cast-in-place　shear　wall,　semi-assembled　shear　wall　has　good　seismic　behavior,　cast-in-place　columns　improve　its　bearing　capacity,　ductility　and　energy　dissipation　capacity,　and　it　can　be　used　in　the　low-rise　shear　wall　structures.
