| 摘要: |
| 对8根参数不同的矩形钢管混凝土短柱进行了轴心受压试验,分析了试件的破坏形态,基于线性莫尔强度准则提出了一个轴心受压矩形钢管混凝土短柱极限承载力计算公式,并用其他文献的试验成果对其进行了验算.结果表明,所得计算结果与试验数据吻合,可为工程设计提供参考.通过比较,验证了按照《矩形钢管混凝土结构技术规程》(CECS 159:2004)提供的轴心受压短柱承载力计算公式进行设计,其结果是安全可靠的. |

| Abstract: |
| Experiments were carried out on 8 short rectangular concrete-filled steel columns which have different parameters under axial loads.A formula of ultimate bearing capacity based on the linear Mohr-coulomb criterion was submitted by analyzing the breakage of these columns.The formula was verified with experiments and other papers' data.The computational results are in line with experimental data.The conclusions can be referenced for engineering design.It is reliable that the parameter of the specification is comparable with technical specification for structures with concrete-filled rectangular steel tube(CECS 159:2004). |
