基于递推随机有限元法的结构可靠度研究

ombining recursive stochastic finite element method and JC method, a new method is presented to calculate structural reliability indices. Numerical example shows that the reliability indices from recursive stochastic finite element method are much better than that of perturbation stochastic finite element method based on the 2th order of Taylor series. It is also shown that numerical results obtained through the new method are close to that of Monte-Carlo simulation method in relatively large fluctuation range.
