| 摘 要： | 共进行了9根无明显屈服台阶的钢管混凝土短柱和2根有明显屈服台阶的钢管混凝土短柱的轴压试验,对两者的破坏形态、极限承载力、荷载-应变曲线及荷载-组合材料的泊松比曲线等进行了研究和分析,研究结果表明前者破坏的形态具有剪切破坏的特征,且有一定的延性破坏特征.若定义无明显屈服台阶钢材拉应变达到2000ug时对应的应力为名义屈服应力,应用已有的钢管混凝土轴压短柱承载力计算公式,所得的计算值与实际值吻合较好. |

| Abstract: | The experimental research was performed on 11 specimens of short steel tubular columns filled with concrete under axial compression.9 specimens are made of no-yield-point steel tubes and two specimens are normal concrete-filled steel tubes.Detailed strain measurement and analysis were conducted for the longitudinal elements.Test results indicate that two kinds of short steel tubular columns filled with concrete make a great difference.If the nominal yield point is defined as the stress when the strain reach... |
