摘要
本文应用有初始几何缺陷的壳体非线性应变分量公式及内时本构理论，对冷却塔在重力作用下的内力进行了弹塑性大变形计算，分析了常见的几种缺陷对冷却塔内力分布的影响。对于工程实际中有缺陷的冷却塔的整体性能分析具有重要意义，可以为工程设计提供理论基础。
On the basis of nonlinear strain components of shell with initial geometric imperfections and intrinsic time constitutive theory,the paper calculated the elastoplastic large deformation stress resultant of cooling tower under itself weight,and analyzed the effects of several general imperfections on stress resultant distribution of cooling tower.The results are of important meaning to the global property analysis of practical cooling tower with imperfections,and will provide theoretic foundation for engineering design.
