有限元ANSYS在钢管混凝土柱分析中的应用

摘要

对3个相同尺寸的圆钢管混凝土短柱，按不同的偏心率进行了加载试验，并利用有限元软件ANSYS进行了模拟分析。通过有限元分析结果与试验结果的比较，验证所建立的ANSYS三维模型的正确性，可应用于圆钢管混凝土短柱的理论研究和工程分析。%Three short columns of concrete-filled circular steel tubular with same size are made in this paper, and they are tested by different eccentricity, simulated by using the finite ele-ment software Ansys. By comparing the results of finite element analysis and experimental, verify that the three - dimensional model of Ansys is Correct, and can be applied the heoretical re-search and engineering analysis of short columns with concrete-filled circular steel tube.
