To　explore　the　eccentric　compressive　behaviors　of　partially　encased　recycled　aggregate　concrete　(PERAC)　columns　after　exposure　to　high　temperatures,　12　columns　were　tested　in　this　paper,　including　3　columns　under　axial　load　as　controls.　Factors　considered　in　the　experiment　were　replacement　levels　(r)　of　recycled　coarse　aggregate　(RCA),　temperature　(T),　and　relative　eccentricity　(e/H).　The　test　results　show　that　the　temperature　rising　of　webs　is　effectively　delayed　by　protection　of　recycled　aggregate　concrete　(RAC).　And　the　post-heated　PREAC　column　has　higher　ductility　under　eccentric　load　due　to　the　better　deformation　capacity　of　RAC　than　that　of　natural　aggregate　concrete　(NAC).　Similar　to　the　effect　of　T,　when　the　e/H　adds　from　0　to　0.2,　both　ultimate　axial　strength　and　initial　stiffness　of　columns　decrease　significantly.　When　e/H　adds　from　0.2　to　0.4,　flanges　away　from　the　loading　axis　are　gradually　changed　from　compression　to　tension.　All　columns　eventually　fail　due　to　local　buckling　of　flanges　near　loading　axis.　Compared　with　partially　encased　concrete　(PEC)　columns,　the　r　of　50%　is　beneficial　for　PERAC　columns　to　get　better　ductility　and　maintain　stiffness.　In　addition,　the　modified　method　based　on　the　code　T-CECS719-2020　can　be　used　to　predict　the　ultimate　strength　of　PERAC　columns　after　exposure　to　high　temperatures.
