| 摘 要： | 基于考虑系统参数不确定性的可靠度分析的快速积分法，提出了一种估计结构可靠度对系统参数敏感性的简便算法，该方法方便实用，对于考虑大量不确定性参数的结构，可迅速找出对可靠性影响很小的因素，并将其作为确定性量处理，最后以两个算例对此方法进行了验证。

| Abstract: | Simple sensitivity measures of reliability to system parameters is proposed in this paper. The sensitivity is determined in the initial stage of the reliability analysis and is useful in determining those uncertain parameters that should be included in the remaider of the analysis. Two examples using the proposed method are given. It has been proved that the proposed method is very effective. |
