| Abstract: |
| A numerical method for dynamic reliability analysis of nonlinear random vibration system is presented. Based on the Bouc-Wen hysteretic model and first passage failure criteria, the probability perturbation scheme and the fourth moment method are extended to discuss dynamic reliability assessment of stochastic multi-degree-of-freedom hysteretic system with independent failure modes. Numerical example indicated that system characterized by independent random parameters, the responses were strongly and dynamic correlated. Results obtained by proposed method were agreed with Monte-Carlo simulation very well, which was verified that the presented numerical method could employ for engineering problem with highly accuracy. |
