基于ANSYS的钢管混凝土轴压短柱承载力分析

Analysis of the bearing capacity of concrete-filled steel tube stub column subjected to axial compression based on ANSYS

采用大型通用有限元软件ANSYS对钢管混凝土短柱的轴压全过程进行了数值模拟,得到构件轴向受压的荷载—应变关系,并与已有文献中的试验结果进行了比较,结果表明,ANSYS的计算结果与试验结果基本吻合,指出利用有限元软件分析钢管混凝土构件的可行性和可信性。

This paper carries out numerical simulation on the whole process of axial compression of concrete-filled steel tube stub column by using large finite element software ANSYS, gets the load-strain relationship of member under axial pressure, compares it with the test result in existing literature, which shows that the computing result by ANSYS is in compliance with the testing result, and points out the feasibility and creditability of using finite element software to analyze concrete-filled steel tube member.
