摘要

对配筋钢管混凝土柱的轴心受压性能进行了试验研究和理论分析；研究了配筋钢管混凝土短柱的受力性能、变形能力和破坏形态，给出了变形和极限承载能力的试验结果；分析了加配钢筋的作用及其对钢管混凝土柱变形和极限承载力的影响。最后探讨了配筋钢管混凝土短柱轴心受压承载力的计算方法，给出了简化计算公式。结果表明，钢管混凝土短柱加配钢筋以后，改变了其破坏形态，提高了其极限承载能力和变形性能。

Abstract

Experiments and analysis were carried out for the axial compression performance of reinforcement concretefilled tubular steel(CFTS). The deformation capacity and ultimate load capacity were investigated with the analysis of loadbearing behavior

deformation capacity and failure modes of the reinforcement CFT short columns. And the influence of reinforcement on the deformation and ultimate load capacity were analysed as well. Finally

the calculation method for axial bearing capacity of reinforcement CFT short column was discussed and a simplified calculation formula was proposed. It was indicated that the columns’ failure modes were changed and their ultimate load capacity and deformation performance were improved by reinforcement.
