This　paper　proposed　a　method　to　enhance　the　energy　dissipation　capacity　of　recycled　aggregate　concrete　(RAC)　shear　walls　reinforced　with　ultra-high　strength　bars　(UHSB).　The　proposed　method　encases　circular　steel　tubes　within　the　boundary　elements　of　walls.　With　the　presence　of　steel　tubes,　steel　fibers　and　axial　load　level　as　primary　research　variables,　five　RAC　shear　walls　were　fabricated　and　tested　under　reversed　cyclic　lateral　force　and　constant　axial　compression　to　verify　the　effectiveness　of　the　proposed　method.　The　test　results　showed　that　the　presence　of　steel　tubes　upgraded　lateral　resistance　and　enhanced　energy　dissipation　capacity,　while　causing　some　subtle　splitting　cracks.　Due　to　the　yielding　of　the　steel　tubes,　the　encasement　of　the　steel　tube　increased　residual　drift　ratio　at　large　drift,　but　the　measured　residual　drift　ratios　of　test　walls　still　were　kept　less　than　0.5　%　until　2.5　%　drift　ratio.　The　addition　of　steel　fibers　delayed　cracking,　constrained　the　cover　concrete　and　reduced　damage　to　the　specimens.　Test　results　also　indicated　that　increasing　concrete　strength　and　axial　compression　level　could　enhance　the　lateral　resistance　of　the　proposed　wall.　In　addition,　a　numerical　analytical　method　is　presented　to　analyze　the　cyclic　behavior　of　the　proposed　shear　walls.　Good　agreement　was　observed　between　the　measured　and　calculated　hysteretic　loops.
