摘要
本文针对高耸结构强度这一关键问题,提出用随机有限元法对其进行可靠性分析,克服了用传统方法分析所带来的不足,并通过两个算例进行比较,进一步证明了在对高耸结构进行可靠性分析时,随机有限元法要比传统方法更精确。在计算中采用自编部分程序与通用的SAP5程序相结合的方法,减小了自编程序的工作量。
In this paper, a stochastic FEM for the reliability analysis of high structure is developed, which overcomes the shortcomings of reliability analysis based some common methods. the combinations of self-edit program and the common SAP5 program is employed which greatly reduces the amount of self-edits.
