摘　　要：基于随机有限元的可靠度研究方法对钢管混凝土轴心受压短构件进行了可靠度分析,分析结果表明:在各随机变量中,材料弹性模量对钢管混凝土轴心受压短柱可靠度指标影响最大,几何尺寸随机变量次之。Based on reliability research method of stochastic finite element,the reliability of axially compressed concrete filled steel tube is studied in this paper.Results show that elastic modulus having the greatest effect on axially compressed concrete filled steel tube columns,and random geometry size variables having the less effect with random variables.

关 键 词：钢管混凝土 随机有限元 可靠度 轴心受压
