| 摘 要： | 进行12个圆钢管薄壁空心混凝土轴压短柱轴压承载力的试验研究,考察轴压承载力—变形特性以及破坏模式,分析了圆钢管轴向、环向变形的发展规律,试验研究表明当薄壁混凝土壁厚达到一定厚度后,圆钢管内的薄壁空心混凝土在环向形成较好的拱效应,能有效地阻止外侧钢管局部失稳。

| Abstract: | 12-short centrifugal hollow thin-wall concrete-filled circular steel-tube columns were tested under axial compression load,and its failure mode and bearing capacity-deformation behavior were investigated.The strain patterns of steel-tube in axial and transverse direction were studied.Test study shows that the arch effects can be formed well when the thickness of thin-wall concrete attains to a certain value,and avoiding the occurrence of local buckling of steel-tube. |

| Keywords: | centrifugal hollow thin-wall concrete-filled circular steel-tube short column axially compressive behavior failure mode |
