用一次二阶矩法分析结构可靠度需反复迭代求解。本文提出合理确定迭代初值的方法,以减少迭代次数,加速计算收敛。计算结果表明,采用本文方法可使计算大为简捷。
The analysis of structural reliability using a second-order moment method requires repeated iterations. This paper proposes a method for reasonably determining initial values of iterations to reduce the number of iterations and accelerate convergence. The calculation results show that using this method can greatly simplify the calculation.
