结构鲁棒设计的前提是预测结构的时变性能和鲁棒性的定量评估。因此，必须根据现有信息选择适当的数据模型来考虑不确定性。本文在广义不确定性模型模糊随机性的基础上，提出了基于模型、无模型和混合的不确定性结构行为预测方法。所引入的鲁棒性度量能够评估模糊随机结构响应下的鲁棒性。
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.
