In order to reveal the mechanical properties of CFRP recycled aggregate concrete long columns under axial compression load, we designed 7 experimental members for the test. The specimens parameters are recycled coarse aggregate replacement percentage, slenderness ratio and layers of CFRP jackets. According to the test, the failure process and patterns were obtained, and the curve of load-displacement were measured. The influence of recycled coarse aggregate replacement ratio, slenderness ratio, layers of CFRP on the bearing performance of CFRP circular steel tubular confined recycled aggregate concrete long columns were analysed.
