| Abstract: |
| The research of structural reliability includes randomness model,fuzzy model,non-probabilistic model.In this paper,the shortcomings of traditional randomness model are discussed.Based on interval arithmetic,a fuzzy reliability measure and analysis methodology for structural reliability computation is presented with the principal of Monte Carlo.The feasibility of the proposed theory is explained in physics and geometry.The failure possibilistic reliability colligates more structural information,and can represent the structural practical reliability.At last,the optimization design model based on fuzzy reliability is discussed.The utility of the presented methodology is demonstrated by examples. |
