This article presents an approach to assess safety levels of structures. A new formula for determining the fuzzy reliability of structures  is proposed  for the case where the  set of loading effect and set of structural durability are general fuzzy sets. Illustration example concerning the  bending strength evaluation of a simple-beam structure, is presented with the choice  of triangular fuzzy sets for loading effect and structural durability.Key words: Fuzzy logic and application, fuzzy reliability.
