| 摘 要： | 为了进一步研究方钢管-钢骨高强混凝土轴心受压短柱的特性,综合考虑钢骨存在对混凝土的影响,修正了方钢管混凝土核心约束混凝土应力-应变模型;采用纤维模型法编制了非线性分析程序,计算了荷载-纵向应变关系曲线,并与有关文献的试验曲线进行了对比,计算结果与试验结果吻合得很好.最后,通过对大量计算结果的回归分析,得出了实用的轴压短柱承载力计算公式.

| Abstract: | To study further the properties of an axially-loaded short column of square steel tube filled with steel-reinforced high-strength concrete,an improved stress-strain model was developed for confined core concrete considering comprehensively the effect of steel-reinforcements on concrete.Fiber modeling was introduced in programming a nonlinear analysis to compute the relationship between loading and longitudinal strain,and the result is compared with the experimental ones in earlier works.The computed results... |
