In this paper, a concept for time‐dependent reliability assessment of civil engineering structures is presented. This concept bases on the uncertainty model fuzzy randomness. The time‐dependent behaviour of materials with fading memory is captured by means of rheological models using uncertain fractional time derivatives. The presented method can be applied to the reliability assessment of engineering constructions. (© 2009 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
