To　investigate　the　post-earthquake　repairability　of　the　resilient　structure　utilizing　ultra-high　strength　bar,　an　earthquake-damaged　piloti-type　masonry　structure　specimen　reinforced　with　ultra-high　strength　bar　was　rehabilitated　through　a　composite　rehabilitation　strategy.　The　rehabilitation　approach　incorporated　a　prefabricated　steel　sleeve　and　carbon　fiber　reinforced　polymer　was　adopted　for　the　frame-shear　wall　structure　at　the　piloti-storey,　along　with　a　combination　of　steel　plate　application　and　steel　mesh　mortar　for　repairing　the　masonry　wall.　The　seismic　behavior　of　the　rehabilitated　structure　was　investigated　through　quasi-static　test　and　OpenSees　numerical　simulation　platform.　The　results　showed　that:　The　piloti-type　masonry　structure　with　ultra-high　strength　rebar　showed　excellent　repairability.　The　rehabilitation　strategy　in　this　study　significantly　enhanced　the　stiffness　of　the　damaged　recycled　aggregate　masonry　wall,　improved　the　shear　resistance　of　the　shear　wall,　and　enhanced　the　deformation　performance　of　the　rehabilitated　piloti-type　structure.　In　comparison　with　the　control　specimen,　the　stiffness　degradation　rate　of　the　rehabilitated　specimen　decreased　obviously,　the　peak　carrying　capacity　and　ultimate　drift　increased　by　21.6　%　and　35.4　%,　respectively.　Moreover,　the　piloti-storey　drift　of　the　rehabilitated　specimen　can　reach　2　%.　These　research　findings　serve　as　a　solid　foundation　for　further　exploration　of　post-earthquake　repairability　in　resilient　structures　and　the　seismic　performance　of　rehabilitated　structures.　©　2024
