| 摘 要： | 经过对14根钢管混凝土中长柱承载力的试验研究,发现钢管混凝土中长柱的极限承载能力与其长细比无一定的对应关系,亦即在试验的长细比范围内钢管混凝土柱的承载能力对长细比并不敏感,经分析计算给出了一种新的承载力计算公式,计算结果与试验结果吻合较好,可用于指导工程实际.

| Abstract: | Experimental researches on fourteen concretefilled tubes with five kinds of slenderness ratio were carried out.It is found that the bearing capacity of concrete-filled steel tubular colummns has no corresponding relation to slenderness ratio,meaning it is not actively responsive to the slenderness ratio.The formula for the calculation of the limit bearing capacity of concrete-filled steel tubular long columns with axial compression were presented,and the calculated results tally well with that of the experiments,which may provide fundamental guidance for the related engineering practice. |
