本文试图研究钢管再生混凝土柱的循环性能。对10根RACFST柱和3根普通钢管混凝土柱进行了13个圆形截面试件的轴压和弯压循环加载试验。试验中的参数为：（1）混凝土类型：普通混凝土和再生骨料混凝土;（2）轴压比（n），从0.05到0.52。结果表明，在恒定轴压荷载和周期性增加的弯曲荷载作用下，RACFST柱的性能与普通钢管混凝土柱相似，且具有较高的延性和耗能能力。
This paper is an attempt to study the cyclic performances of recycled aggregate concrete (RAC)-filled steel tubular columns. Thirteen specimens with circular section, including 10 RAC-filled steel tubular (RACFST) columns and 3 reference normal concrete-filled steel tubular (CFST) columns, were tested under constant axial load and cyclically increasing flexural loadings. The parameters in the test are: (1) concrete type: normal concrete and recycled aggregate concrete; and (2) axial load ratio (n), from 0.05 to 0.52. It was found that, generally, the performances of RACFST columns under constant axial load and cyclically increasing flexural loadings are similar to the corresponding normal CFST columns, and RACFST columns can also exhibit high ductility levels and energy dissipation abilities.
