| 中文摘要: |
| 给出了结构可靠性分析方法－改进一次二阶矩法（AFOSM）一套新的计算公式，并以纤维增强复合材料层合板结构为研究对象，运用随机有限元法（SFEM）数值计算方法分析各单层板的可靠性指标β。文中算例计算结果表明，本文给出的计算公式是合理的和有效的，而且用它所得计算结果比用原AFOSM所得结果更加精确。 |
| 英文摘要: |
| A set of new equations of the advanced first\|order second\|moment method (AFOSM) for structural reliability analysis are presented. The fiber reinforced composite laminates is used as the object of study, and the reliability index of each lamina is calculated by the equations and the stochastic finite element method (SFEM). The calculating result of the given example indicates that the equations are rational and valid, and the result from the equations of AFOSM has more precision than that from the old AFOSM. |
