摘要:

针对钢管混凝土快速发展的现状,介绍了钢管混凝土的圆形截面、矩形截面、中空夹层截面和实心双层截面等形式及受力特点。为了能方便地分析各种截面形式的承载力性能,对几种截面形式的轴心受压极限承载力用大型有限元软件ANSYS,加入不同的混凝土本构关系进行了承载力分析计算,得到了这些截面形式的钢管混凝土的承载力-位移关系曲线以及应力云图; 并同已有的试验或计算结果进行了比较,其结果较为吻合。对于钢管混凝土的截面选择和极限承载力的计算有一定的参考意义。

Abstract:

According to the fast development of concrete-filled steel tube, the loading characteristics for the concrete-filled steel tube with sections of circle, square, hollow sandwich and double skin were introduced. In order to analyze the load capacity of several kinds of section types, the loading of axial compression tests were analyzed with program ANSYS. And different relations of stress-strain were considered. The load-displacement curve and stress nephogram of concrete-filled steel tube were analyzed. The results are accordant with the corresponding literatures. It is important to choose the sections and the load capacity of concrete-filled steel tube.
