摘要
提出一种推广一次二阶矩法的算法，解决了关于相关正态随机向量的非线性极限状态方程下结构可靠度计算问题，在理论上论证了方法的可行性，实例计算表明了方法的有效性．
The problem on the structual reliability under non linear limit state equation concerning related normal random vector has been solved by presented first order second moment method.The feasibility of this method is deduced thoretically and the effectiveness is demonstrated by the computation of some examples.
