| 摘 要： | 通过 8根圆形薄壁钢管混凝土轴压短柱试验 ,研究了不同径厚比、混凝土强度等级、含钢率等参数 ,对薄壁圆钢管混凝土轴压短柱力学性能的影响。试验表明 ,由于有内填混凝土的支撑作用 ,钢管壁的局部屈曲和屈曲后的性能有很大提高。与常规壁厚的钢管混凝土轴压短柱相比较 ,达极限承载力时的破坏模式也有较大的变化

| Abstract: | Eight stub-column tests of concrete-filled thin-walled steel tube(CFTST)have been carried out.The influencing parameters,such as diameter-to-thickness ratio,strength grade of concrete,rate of steel,on the static mechanics behavior of CFTST are investigated.The results show that the local buckling and post buckling behaviors of the steel tube have been considerably increased by the support of concrete.As compared with general concrete filled steel tube,the failure mode at their Load carrying capacity has obviously changed. |

| Keywords: | CFTST stub column test local stability failure mode |
