| 摘 要： | 本文所讨论的是试件宽度与钢板厚度之比不大于15的厚壁方钢管,内填高强混凝土的短柱,共进行23个中心受压及偏心受压构件试验,分析了受力性能,并对受力过程进行了计算机模拟计算,提出了实用的强度计算公式,并建立了N-M相关方程。计算结果表明,理论值与试验实测结果吻合较好。

| Abstract: | In this paper the behavior of concrete filled steel square thick-wall tubular stub is studied, the ratio of specimen width to thick- ness of steel plate is less than 15. 23 specimens under central loading and eccentrical loading are tested. Behavior under loading has been ana- lysed, and loading process has been simulated and calculated on computer. A formula for practical strength calculation is proposed and N-M relat- ed expression is set up.Calculation shows that theoretical values coincide well with experimental values. |
