The　fire-resistant　performance　of　recycled　concrete　member　was　studied　to　further　promote　the　application　of　recycled　concrete.　Two　concrete　tubular　structure　models　with　different　concrete　strengths　were　designed　and　tested　under　both　vertical　load　and　high　temperature　according　to　the　standard　heating　curve　in　the　test　furnace.　The　two　models　were　made　from　recycled　concrete　with　both　the　coarse　and　fine　aggregate　replacement　rate　of　100%.　Their　recycled　concrete　was　specified　as　C20　and　C30,　respectively.　The　fire　endurance,　temperature　field,　failure　characteristic,　wall　deflection　and　vertical　displacement　were　comparatively　analyzed.　The　recycled　concrete　temperature　field　of　the　specimens　was　also　simulated　by　running　ABAQUS　software　and　they　agreed　well　with　the　experimental　results.　Results　show　that　with　the　increase　of　the　strength　of　recycled　concrete,　fire　endurance　and　fire　resistance　of　the　tubular　structure　decrease　and　the　structure　tends　to　fail　in　expansion　under　high　temperature.
