【摘要】 基于概率理论探讨了蒙特卡罗(MonteCarlo)有限元法的概念,采用大型通用有限元程序ANSYS提供的APDL语言将其结构分析与其PDS模块的统计分析能力相结合,实现可靠性分析的蒙特卡罗有限元法。结合建筑钢结构设计算例详尽叙述了该方法实现的流程。由于结构对适用性的控制要求低于对安全性的控制要求,适用性分析所用样本数只需承载能力极限状态分析时样本数的千分之一就能满足工程精度要求。更多还原

【Abstract】 By adopting APDL language resulted from senior standard finite element program, combined with its structure analysis and statistic analysis capability of the PDS module, the reliability analysis of the Monte Carlo Method has reached. The thesis specified with algorithm at large the realization process of the said method. Since the structure has a lower control request to applicability analysis than to the safety, the samples needed in applicability analysis are only one in a thousand of the samples needed in ultimate limit analysis of the bearing capacity that can fully satisfy the accuracy specification in engineering.更多还原
