摘要
为了能从总体上把握钢管混凝土构件的受力特性,本文选取典型钢管混凝土构件-圆钢管混凝土构件作为研究对象,建立构件的有限元分析模型.通过有限元分析软件ANSYS10.0对其进行数值分析,研究该典型钢管混凝土构件的受力机理、应力分布情况和破坏形态.并与理论计算结果进行对比,验证了钢管混凝土的基本承载力计算公式.
In order to grasp the overall mechanical behavior of CFSTS, the paper sets up a model of finite element analysis by taking a typical concrete -filled steel tubular structure, namely, a circular concrete -filled steel tubular structure, as its research subject. It then studies its bearing mechanism, stress distribution and failure modes. The correctness of the formula for computing its basic bearing capacity is further verified by respectively comparing the above findings with the theoretical results.
