摘　　要：为了研究CFRP钢管再生混凝土长柱的轴压性能,以再生粗骨料取代率、长细比、包裹CFRP布层数为变化参数设计了7个试件进行轴压试验,观察了试件的受力全过程和破坏形态,获取了试件的荷载-位移曲线,分析了再生粗骨料取代率、长细比、包裹CFRP布层数对CFRP钢管再生混凝土长柱承载性能的影响。In order to reveal the mechanical behavior of CFRP （Carbon Fiber Reinforced Polymer）circular steel tubular confined recycled aggregate concrete long column under axial compression loading.7 specimens were designed for 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, the curve of load - displacement were measured.The influence of recycled coarse aggregate replacement ra- tio, slenderness ratio,layers of CFRP on the bearing performance of CFRP circular steel tubular confined recycled aggregate concrete long columns were analysed.
