摘要
根据结构可靠指标 β为在标准正态坐标系中原点至极限状态曲面最短距离的基本定义 ,在广义随机空间中 ,将在欧洲通用的确定变量独立时 β值的 Hasofer- L ind方法推广至适用于变量相关时的情况。 3个算例的对比结果验证了新提出计算方法的正确性。
The structural reliability index β is defined as the distance from origin to the nearest point of the failure surface in the normalized coordinate system.The Hasofer-Lind reliability index β is generally used in Europe for determining the reliability index of independent variables.This paper extends the method in a generalized stochastic space to be applicable to the condition of variables are correlated.The results obtained by the method for three examples have shown that the β values are equal to the true ones.
