Finite element analysis software is used to establish model to simulate the tests, and parameters analysis is done on the base of numerical model for the influence of the concrete inside and the angle between steel tubes.

• 应用有限元分析软件,建立有限元分析模型进行数值计算,对比试验结果,验证数值模型的有效性,并在此基础上改变钢管内混凝土的填充高度和两向钢管的夹角,进行有限元数值计算,对这两个重要的影响因素分别进行了研究。
