摘要
从计算机搜索的角度出发,提出了一种计算结构可靠度指标的新方法。该法避免了传统的可靠度分析方法(JC法)对复杂非线性功能函数计算不收敛的麻烦,且该法不需对功能函数求导,能广泛应用于复杂非线性功能函数的求解。
Based on the computer seeking, a new algorithm is proposed to calculate the reliability indexes of structures. This method avoids the disadvantages of traditional JC method and has no need to search for the derivatives of limit state functions. So it can be used widely in the reliability indexes of nonlinear limit state functions of structures.
