摘要
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。
A nonlinear stochastic finite element reliability analysis process, based on the FirstOrder Reliability Method, was carried on the hyperbolic cooling tower under wind loadings.Variabilities of material properties and wind loadings were considered. The geometricalnonlinearity of the structure was also studied in total Lagrangian formulation. The 90mhyperbolic cooling tower of Guangdong province was chosen as an example to be analyzed.
