| 摘 要： | 在厚壁圆筒统一强度理论解的基础上,根据外方内圆中空夹层钢管混凝土的特点,通过引入混凝土强度折减系数和等效约束折减系数,将外方内圆中空夹层钢管混凝土等效为外圆内圆中空夹层钢管混凝土,推导了外方内圆中空夹层钢管混凝土轴压短柱的极限承载力公式,并将该公式的计算结果与文献试验结果进行了比较。结果表明:该理论公式是正确可行的,该结果为外方内圆中空夹层钢管混凝土轴压短柱的极限承载力分析提供了理论依据,对工程设计有一定的参考价值。 |
| 关 键 词： | 中空夹层钢管混凝土 统一强度理论 等效约束 极限承载力 |

| Abstract: | Based on unified strength theory solution of thickness cylinder,according to the characteristics and equivalent restriction reduction factor of concrete,circle hollow section(CHS) inner and square hollow section(SHS) outer concrete-filled double skin tubes were equivalent to CHS inner and CHS outer concrete-filled double skin tubes through introducing concrete strength reduction factor.Ultimate bearing capacity formulae were deduced and the comparisons between the calculation results and experiment results were carried out.The results show that the theory formulae are correct and viable.The results offer the theoretical foundation to the research of CHS inner and SHS outer concrete-filled double skin tubes stub columns and provide references for the engineering design. |
| Keywords: | concrete-filled double skin tubes unified strength theory equivalent restriction ul-timate bearing capacity |
