To　further　study　the　seismic　behavior　of　precast　reinforced　concrete　shear　walls　in　which　the　vertically　distributed　reinforcements　are　indirectly　connected　with　a　single　row　of　rebars　spliced　by　grouted　straight-thread　couplers,　quasi-static　tests　are　carried　out　for　five　specimens　with　cast-in-situ　boundary　elements.　Three　specimens　have　cast-in-situ　boundary　element　at　one　end,　while　the　others　have　cast-in-situ　boundary　element　at　both　ends.　The　test　results　indicate　that　the　cast-in-situ　boundary　elements　and　the　precast　shear　wall　work　together　as　one　unit,　horizontal　cracks　and　extended　diagonal　cracks　are　the　main　cracks　of　the　specimens,　horizontal　cracks　run　through　the　interface　between　the　wall　and　the　base　beam,　vertical　rebars　yield　before　the　specimen　reaches　its　strength,　and　the　concrete　crushes　at　the　bottom　of　the　wall.　All　specimens　fail　in　compression-bending　mode.　The　ultimate　drift　ratios　of　specimens　are　1/99~1/62.　The　current　code　formulas　are　suitable　for　calculating　the　compression-bending　strength　of　precast　shear　walls,　and　the　contribution　of　vertical　distributed　reinforcements　should　be　taken　into　consideration.
