摘要： 为研究GFRP管高强混凝土短柱的轴心受压性能，进行了4根不同截面组合柱的轴心受压试验，主要研究其工作机理和破坏形态.试验结果表明:在荷载作用初期，组合柱GFRP管对混凝土没有约束作用，随着荷载作用增加，GFRP管表面出现白纹和轻微的响声；在极限状态时，GFRP管被拉断，并伴随巨大的响声.GFRP管-高强混凝土-钢管组合柱的承载力比GFRP管-高强混凝土-GFRP管组合柱高37%左右.采用统一理论法建立组合柱的轴压承载力计算公式，理论计算结果与试验结果吻合良好.

Abstract: To investigate the axial compression performance for the GFRP high strength concrete short columns， four composite columns with different cross sections were tested under axial compressive load so as to understand the working mechanism and failure mode. The results showed that， in the early stage of the load， the combination column GFRP tube is not bound on the concrete. As the load increases， the GFRP tube surface appears white streaks and a slight noise is noted. In the limit state， the GFRP tube is pulled off accompanying with a huge sound. The carrying capacity of the GFRP tubehigh strength concretethe steel tube composite column is about 37% higher than that of the GFRP tubehigh strength concreteGFRP tube composite column. In the foundation of uniform theory， the formula of ultimate bearing capacity is established， and the theoretical calculations are in good agreement with the experimental results.
