本文提出了一种计算弹性地基圆拱的单元刚度矩阵和固端力列阵的简捷方法,它可供设计人员使用,是一种实用的方法。文中还讨论了单元刚度矩阵的坐标变换和对称性应用。此方法与一般刚架的有限元分析同样方便。
This paper presents a simple method for calculating the element stiffness matrix and the fixed end force array of the elastic foundation circular arch, which is available to designers and is a practical method. The application of coordinate transformation and symmetry of element stiffness matrix is also discussed in this paper. This method is as convenient as the finite element analysis of a general rigid frame.
