To　investigate　the　compressive　behavior　of　partially　encased　recycled　aggregate　concrete　(PERAC)　stub　columns　after　exposed　to　elevated　temperatures,　22　specimens　were　tested.　The　maximum　temperature　suffered,　the　replacement　ratio　of　recycled　coarse　aggregate　(RCA),　the　endurance　time　and　the　spacing　between　links　were　considered　as　the　main　parameters.　It　was　found　that　the　failure　mode　of　post-heated　PERAC　columns　generally　matched　that　of　traditional　partially　encased　composite　(PEC)　columns,　but　the　flange　of　specimens　appeared　premature　buckling　after　undergoing　the　temperature　of　400　degrees　C　and　above.　Additionally,　the　ultimate　strength　and　ductility　of　the　specimens　deteriorated　with　the　elevated　temperatures　and　extended　heating　time.　When　400　degrees　C＜　T　＜=　600　degrees　C,　the　strength　reduction　range　is　the　largest,　about　11%　similar　to　17%.　The　higher　the　replacement　ratio　of　RCA,　the　lower　the　ultimate　strength　of　specimens.　At　the　temperature　of　600　degrees　C,　the　ultimate　strength　of　specimens　with　the　RCA　replacement　ratio　of　50%　and　100%　is　0.94　and　0.91　times　than　that　of　specimens　without　RCA,　respectively.　But　the　specimen　with　50%　replacement　ratio　of　RCA　showed　the　best　ductility　performance.　And　the　bearing　capacity　and　ductility　of　PERAC　stub　columns　were　changed　for　the　better　due　to　the　application　of　links.　When　the　RCA　replacement　ratio　is　100%,　the　ultimate　strength　of　specimens　with　the　link　spacing　of　100　mm　and　50　mm　increased　14%　and　25%　than　that　of　the　specimen　without　links,　respectively.　Based　on　the　results　above,　a　formula　for　calculating　the　ultimate　strength　of　PERAC　stub　columns　after　exposure　to　high　temperatures　was　proposed.
