摘要
为进一步提高钢管混凝土柱承载力及延性,在核心混凝土中配置钢筋。通过6根钢管混凝土短柱与配筋钢管混凝土短柱轴压力学性能试验,对比分析配筋钢管混凝土短柱与钢管混凝土短柱的破坏模式,承载能力及变形能力,试验结果表明,配筋钢管混凝土短柱与钢管混凝土短柱的破坏模式均属于剪切破坏,配筋钢管混凝土短柱无论是承载能力还是变形能力都优于钢管混凝土短柱,基于abaqus软件进行数值模拟,有限元分析计算结果与试验实测结果对比,二者吻合度较好。
Combination of 6 concrete filled steel tubular short column and reinforced concrete filled steel tubular short column axis pressure performance test, analysis of reinforced concrete filled steel tubular short column and the failure modes of concrete filled steel tubular short column, bearing capacity and deformation capacity, the test results show that the reinforcement of concrete filled steel tubular short column and the failure modes of concrete filled steel tubular short column all belong to shear failure, reinforcement of concrete filled steel tubular short column both in bearing capacity and deformation capacity is better than that of concrete filled steel tubular short column, based on abaqus software to carry on the numerical simulation, finite element analysis and calculation results coMPared with experimental measurements, the alignment is good.
