To　promote　the　green　development　of　resilient　cities　and　achieve　resilient　buildings　constructed　with　recycled　materials,　it　is　necessary　to　further　extend　the　engineering　application　technology　of　high-strength　recycled　aggregate　concrete　(HSRAC)　in　resilient　structures.　In　this　paper,　pseudostatic　tests　were　carried　out　on　six　HSRAC　columns　with　ultra-high-strength　steel　bars　(UHSS).　The　test　variables　include　the　UHSS　percentage,　stirrup　ratio,　axial　compression　ratio　and　UHSS　bond　strength.　In　addition,　finite　element　models　were　developed　to　conduct　the　parametric　analysis　and　optimization　assessment.　Based　on　the　experimental　research　and　finite　element　analysis,　the　seismic　performance　and　repairability　of　HSRAC　columns　were　discussed.　The　results　revealed　that　HSRAC　columns　employing　the　UHSS　possessed　excellent　self-centering　capability　and　remarkable　drift-hardening　property.　Well-designed　HSRAC　resilient　columns　can　be　repaired　within　4.0%　drift.　In　addition,　the　engineering　design　references　were　recommended　based　on　reliable　simulation　results.　©　2023　Institution　of　Structural　Engineers
