结构可靠度分析的初值校准方法

Calibration Method for the Initial Value in structural Reliability Analysis

本文在ＪＣ法的基础上，提出了结构可靠度分析的一种初值校准方法。该法可适用于一般情形的结构可靠度计算，包括非线性极限状态方程和非正态分布的变量。通过算例表明，本文方法具有较高的计算效率，一般只需迭代一次便能得到较满意的结果。

Based on the JC method this paper recomends a calibration method forthe initial value in structural reliability analysis. The method is well suited univeaselly, including the cases of non-linear limit state eqcation and non-normal probability distribution,It has high calculation efficiency as shown with example. Needing on only iteration,satisfactory result will be generally got.
