| 中文摘要: |
| 由国际安全度联合委员会推荐的一次二阶矩可靠度方法是国际工程界公认的一种较好的可靠度分析方法（简称ＪＣ法）。这种方法具有迭代格式简单，收敛快的特点。但许多实际计算表明，这种方法只适用于功能函数非线性程度不高的情况，否则不收敛。本文提出一种新的迭代方法，这种方法迭代格式与ＪＣ法同样简单，一般情况下均能保证收敛． |
| 英文摘要: |
| The first-order second-moment rliability method proposed by Joint Committee of Struc-tural Safety is a better method for reliability analysis which has been recognized in the areasof civil engineering around the world(be called JC method for short).This method is simplein iteration and converge fast , but pratical calculation has shown this method can only beused for the case that the nonlinearity of performence function is not higher,otherwise noguarantee converge, So that a new algorithm is developed in this paper,the new algorithm assimple as JC method and can guarantee converge in general. |
