摘要
推导了几何非线性的刚度矩阵和梁柱理论的单元刚度矩阵,解释了二者的异同点,还就典型例题进行了讨论。本文的结果对于稳定问题和几何非线性问题具有一定参考价值。
In this paper, the stiffness matrices of geometric nonlinearity and element stiffness matrices of beam-pillars are derived. The difference between the two and special examples are also discussed. The results obtain may be available for reference to the study of the problems of stability and geometric nonlinearity.
