| 摘 要： | 运用应力场摄动随机有限元分析的基本原理，对单层工业厂房的可靠性进行也分析－＝－建立计算模型并进行离散化，通过结构分析得出结构不确定性对结构响应量的影响，进一步的可靠性分析可得到结构的最小利截面的位置。实例分析表明，应用该方法具有对统计信息要求少、计算量小、结构严谨、结果精确等优点。

| Abstract: | The reliability of single floor factory buildings is analyzed by using perturbation stochastic FEM A model is established and a discretization is carried out The influence of structure uncertainty on structural response is determined The most disadvantageous sections are located by means of more detailed analysis of reliability Example analysis demonstrates that the algorithm is advantageous in less statistical information,smaller computational work,more compact structure and more accurate result |
