Waste　concrete　has　caused　significant　environmental　damage.　With　the　increasing　use　of　recycled　concrete　in　construction,　its　mechanical　properties　and　performance　under　high-temperature　conditions　have　become　critical　concerns.　In　fire　situations,　the　eccentric　behavior　of　recycled　concrete　columns　wrapped　with　H-shaped　steel　sections　may　be　significantly　impaired,　leading　to　a　notable　reduction　in　load-carrying　capacity　and　structural　stability.　To　mitigate　this　issue　and　conserve　natural　resources,　this　study　investigates　the　application　of　recycled　coarse　aggregate　in　partially　encased　concrete　(PEC)　columns.　The　effects　of　temperature　(T),　recycled　coarse　aggregate　replacement　ratio　(R),　and　eccentricity　ratio　(e/h)　on　the　eccentric　compressive　behavior　of　partially　encased　recycled　concrete　(PERC)　columns　after　high　temperatures　were　examined.　Six　PERC　columns　were　designed　for　this　study,　along　with　one　PEC　column　as　a　control　specimen.　The　experimental　results　indicate　that　PERC　columns　exhibit　different　failure　modes,　all　ultimately　failing　due　to　concrete　crushing　and　flange　buckling.　Exposure　to　high　temperatures　resulted　in　a　maximum　mass　loss　of　4.63　%　in　the　specimens.　Among　the　three　variables,　the　eccentricity　ratio　(e/h)　had　the　most　significant　impact　on　the　ultimate　load　capacity　and　ductility　of　the　PERC　columns.　Specifically,　when　the　e/h　ratio　increased　from　0　to　0.2,　the　ultimate　load　capacity　of　the　column　decreased　by　43.9　%,　while　its　ductility　increased　by　26.2%.　Based　on　these　findings,　a　new　formula　for　predicting　the　ultimate　load　of　PERC　columns　after　high　temperature　is　proposed,　providing　an　effective　reference　for　post-fire　PERC　column　analysis.
