摘　　要：简要论述了圆钢管混凝土短柱性能的一个重要方面:确定使短柱压力-应变曲线不再下降的界限套箍系数,并提出了一个确定该界限系数的简单方法,结果与已有试验结果符合,表明所提出方法的基本合理性。An important aspect of the theory of concrete filled circular pipes is to determine the limiting confining coefficient at which the axial force-strain curves become ideal elastic-plastic.This article proposed a simple way for computing this limiting confining coefficient,the results are in good agreement with the test results reported by the literature,implying the correctness of the proposed method.

关 键 词：钢管混凝土 套箍系数界限值
