进行了6根CFRP方钢管再生混凝土短柱和2根方钢管再生混凝土短柱的轴压性能试验。研究了再生粗骨料取代率、CFRP包裹层数对CFRP方钢管再生混凝土短柱受力性能的影响。试验结果表明,CFRP方钢管再生混凝土短柱的承载力随着再生粗骨料取代率的增加而降低；增加CFRP包裹层数,其试件承载力变大。

A total of 6 CFRP square steel tubular confined recycled aggregate concrete short columns and 2 recycled aggregate concrete filled square steel tubular short columns were tested under axial compression load. The influences of the replace rate of recycled aggregate concrete and the layers of CFRP jackets on the compression behavior of CFRP square steel tubular confined recycled aggregate concrete short columns were studied. The results indicate that with the replace rate of recycled aggregate concrete increasing,the specimens have an decreasing trend in the load bearing capacity;the more the layers of CFRP jackets, the higher the load bearing capacity of the specimens.
