摘要
采用有限元法及结构可靠性的基本理论,考虑结构的弹塑性能,研究板失稳时,该种结构系统的可靠性。通过数值例题,证明分析的有效性。
In this paper, the finite element method of the structural analysis and basic theory of the structural reliability are used to perform the reliability analysis for bar-plate sheet structures under unsteady condition, by considering the plate elastoplastic mechanical characteristic. Nu- merical examples are provided to demostrate the validity of above analysis.
