摘要
对13根圆中空夹层钢管RPC(活性粉末混凝土)轴心受压短柱的受力性能进行试验研究,得到圆中空夹层钢管RPC轴心受压短柱随内钢管壁厚变化的承载力及其力学性能特性。在总结已有研究成果的基础上,给出圆中空夹层钢管RPC短柱极限承载力的计算建议公式,并通过ABAQUS有限元软件对试验全过程进行模拟分析,计算得到的承载力和荷载-应变曲线与试验结果较吻合。
The article carries out experiments of 13 RPC （Reactive Powder Concrete） -filled double skin steel tu-bular short columns under axial compression loading, and obtains ultimate capacity and mechanical properties under the inside steel tube wall different thickness of RPC-filled steel tube. Based on the existing research a-chievements at domestic, the article proposes the calculation formula of ultimate capacity of RPC-filled double skin steel tubular. By utilizing the finite element software ABAQUS, the article simulates the process of experi-ment, and obtains ultimate capacity and load-strain curves, which are agree with the experiment results.
