本文用基于一次可靠度方法的非线性随机有限元法分析了双曲冷却塔壳体结构的抗风可靠度，考虑了结构的材料性能空间随机性和荷载随机性，以及结构的几何非线性影响，并且对广东茂名９０米高冷却塔作了分析算例。
This paper analyzes the wind-resistant reliability of the shell structure of a hyperbolic cooling tower using a nonlinear stochastic finite element method based on the first-order reliability method. The spatial randomness of the material properties and the randomness of the load are considered, and the geometric nonlinear effects of the structure are also considered. And an analysis example was made for a 90-meter-high cooling tower in Maoming, Guangdong.
