| 摘 要： | 介绍了离心法生产的空心钢管混凝土构件轴心受压时的工作性能.工作性能是随着套箍系数和空心率的变化而变化,呈系列化和连续性.符合统一理论的推断.进行了圆形,方形和多边形轴压短柱的试验,试验结果与计算结果吻合很好.同时导出轴心受压时的强度设计公式,该公式对各种多边形截面和方形截面都适用,使用方便,设计简单.

| Abstract: | In this paper,the behaviors of centrifugal H-CFST are introduced.The behaviors of H-CFST change with the change of confining index and hollow ratio,which agrees with the deduction of "Unified Theory".A series experiments of various forms H-CFST,including circular,sixteen-side,octagonal and square cross-sections are completed.The test results are coincided with the calculated results well.The strength calculating formulas are derived,which can be used to design non-circular cross sections H-CFST members (conveniently.) |
