| 摘 要： | 通过钢骨—铜管混凝土组合柱单调压弯试验，分析了轴压比一定时，配骨指标不同的组合柱在水平荷载作用下的受力性能，讨论了这种新型组合柱的破坏形态、截面应变分布、荷载-位移关系曲线、承载能力和延性。试验结果表明，钢骨—钢管混凝土压弯组合柱具有很好的承载力和延性。

| Abstract: | Based on the test of monotonous pressure and bending loaded circular steel tube columns filled with steel-reinforced concrete, the mechanical behaviors of the composite columns under horizontal loading, variable section steel index and constant axial load ratio are analyzed. The failure forms, strain distribution in the section, load-displacement circulation curves, bearing capacity and ductility of the columns are discussed. The test results show that circular steel tube columns filled with steel-reinforced concrete are of excellent bearing capacity and ductility. |
