The　purpose　of　this　study　is　to　promote　the　application　of　high-strength　reinforcement　and　recycled　aggregate　concrete　in　post-earthquake　repairable　precast　structures.　Three　large-scale　recycled　concrete　columns　with　ultra-high-strength　steel　bar　were　designed　and　tested　under　quasi-static　cyclic　loads.　The　feasibility　of　semi-precast　columns　is　verified,　i.e.,　the　concrete　shell　of　the　outer　tube　is　precast　first,　and　then　the　precast　external　shell　is　used　as　a　formwork　to　cast　concrete　into　the　tube.　The　design　parameters　include　axial　load　and　the　addition　of　steel　fibers.　The　results　indicate　that　all　specimens　exhibited　a　good　deformation　capacity　with　an　ultimate　drift　ratio　greater　than　4%.　Increasing　axial　load　will　increase　the　lateral　load　capacity　of　the　specimen　by　21%,　while　the　deformability　and　repairability　decrease.　Adding　steel　fibers　to　the　precast　external　shell　can　increase　the　lateral　load　capacity　by　10%,　as　well　as　the　deformability　and　repairability　of　the　specimen.　Due　to　the　low　bond　strength　of　ultra-high-strength　steel　bar,　it　slips　at　the　column　footing　in　the　tensile　side.　Eventually,　the　fiber-based　model　simplified　flexural　capacity　calculation　model　considering　the　ultra-high-strength　steel　bar　slippage　in　the　tensile　zone　are　established.
