摘要
本文利用准循环矩阵方法计算了弹性地基上自然通风冷却塔在下部支承结构（支柱与环梁）有缺断时，下部结构的内力，利用脉冲函数模拟重新分布的集中力，对壳体进行了二次计算，在内力协调条件下，完成了结构整体的应力分析．体现这一方案的有限元程序（ＷＢＳ）对若干实例给出了合理的计算结果．
The stress analysis on the supporting pat of natural cooling tower built on elastic foundation is conducted ed the method of circulatory matrix. Using pulse function to simulate concentrated force, a second stress analysis for revelutional shell is perfomed under the compatibility condition of the internal force. The methed has been used in cooling tower engineering. Several numeric examples, are Provided to demonstrate the effectiVeness of the finite element program (WBS).
