摘　　要：介绍了以圆钢管为钢骨的劲性高强混凝土柱的抗震性能研究的试验概况,在此基础上采用条带有限元法进行了弯矩-轴力相关曲线的数值分析,计算结果与试验结果大致吻合,可以用于确定该类柱在偏压状态下的极限承载力。The general situation of earthquake-resistant behavior experiments of high concrete columns reinforced with concrete filled steel tube is presented. Based on the experimental results, the numerical analysis of load-moment interaction diagram for the columns is completed using strip finite element analysis method. The calculation results are in basic agreement with those of the experimental values, so the numerical analysis method can be used to determine the ultimate bearing capacity of the columns under eccentric compression.

关 键 词：高强混凝土 劲性混凝土柱 偏压
