| 摘 要： | 报导了钢管高强混凝土长柱和偏压柱力学性能试验的结果。研究表明，钢管高强混凝土长柱的承载能力和极限变形率随长细比Le／D的增大而下降。钢管高强混凝土偏压柱在相同的长细比下。随着偏心率的增加，试件的承载能力降低，纵向位移率降低。最后给出了钢管超高强混凝土长柱和偏压柱承载能力计算公式。

| Abstract: | This study continued the investigation into the mechanical properties of high strength concrete filled steel tubular columns,(HSCFST),specifically the properties of slender and eccentrically loaded columns subjected to a compressive loading.The test results for slender columns show that the load bearing capacities and maximum displacement ratio(the ratio of displacement to the initial length at peak load) of the column decreases as slenderness ratio,determined as the ratio of the length to diameter,increases.The test results for eccentrically loaded columns show that when the slenderness ratio is kept constant,the load bearing capacity and maximum strain decrease as the eccentricity ratio increases.The formula for calculating the load bearing capacities of slender columns and the eccentrically loaded columns are presented. |
