Abstract: Robust design of structures presupposes the prediction of time-dependent structural behaviour and the quantitative assessment of robustness. Thereby, the uncertainty has to be considered by means of adequate data models selected in accordance with the available information. On the basis of the generalised uncertainty model fuzzy randomness, model-based, model-free and hybrid approaches for the prediction of uncertain structural behaviour are presented in this paper. The introduced robustness measure is capable to assess the robustness under consideration of fuzzy random structural responses.
