| 摘 要： | 通过6根钢骨-方钢管混凝土组合短柱的偏心受压试验,研究该组合柱的受力性能.试验结果表明:钢骨-方钢管混凝土偏心受压组合短柱试件的破坏是由于方钢管局部出现凸曲而导致承载力的下降而引起的；混凝土的强度、方钢管的宽厚比和钢骨的用量都对组合柱的受力性能有着显著影响；通过截面应变分析,可以近似地认为偏心受压组合柱符合平截面假定.

| Abstract: | Six composite stub concrete columns with skeletal core and square steel tubular envelope were tested under eccentrically-loaded compression and their kinematic performance was investigated.Their experimental result showed that the reason of failure of these columns was that local buckling took place with the column specimen and its bearing capacity descended.The concrete strength,width-to-thickness ratio of square steel tube and the amount of steel skeletal core had significant effect on the bearing-capacit... |
