AN EVIDENCE-THEORY-BASED RELIABILITY ANALYSIS METHOD FOR UNCERTAIN STRUCTURES

Funds: The project was supported by the National Natural Science Foundation of China (11172096), the National Basic Research Program (2010CB832705), the Program for New Century Excellent Talents in University (NCET-11-0124) and Fok Ying-Tong Education Foundation for Young Teachers in the higher Education Institutions of China (131005).
  • 摘要: 提出了一种基于证据理论的结构可靠性高效求解方法. 通过构造优化问题求解极限状态方程的非概率可靠性指标及设计验算点, 并构造一辅助区域. 通过辅助区域显著减少需要进行极值分析的焦元个数, 并基于区间分析方法减少焦元上极限状态方程的计算次数, 从而有效降低计算成本. 数值算例及工程应用验证了该方法的有效性.
