摘　　要：在文献[6]的基础上,提出了框架结构与Wink1er地基梁相互作用分析的新超元法,导出了一种新的超级单元刚度矩阵。该超级单元刚度矩阵不仅反映了上部框架结构和基础梁的刚度贡献,而且反映了Winkler地基的刚度贡献。以此新的超级单元分析整体结构,提高计算精度,简化计算。Using a new super method to analyze the interaction of a frame structure and a foundation beam on Winkler ground is presented based on the method [ 6]. In this paper, the new super element stiffness matrix is derived, which reflects not only the stiffness of upper structure and foundation beam, but also that of Winkler foundation. The method is applied to analyze the whole structure with high accuracy and simple calculation.
