摘要: 本文利用有限元方法进行分析,并通过函数逼近方法拟合,提出了T型、正交X型管节点局部柔度的参数公式。公式的计算结果与国外参数公式的计算结果及钢模型试验结果进行了比较,本文公式结果更接近试验值,也是对文[11]所给公式的改进和扩展。

Abstract: According to the results calculated by the finite element program TJSDAP the parameter formulas of local flexibility of T and X type tubular joints are presented by using function fitting method. Numerical results of T type tubular joints are quite coincident with the results of the experiments and that obtained by some other parameter formulas presented aboard.
