International audienceThis contribution explores the use of robust optimization theory in the context of the limit analysis and plastic optimization of structures in presence of uncertainty. Limit analysis is an efficient tool for computing in a direct manner the ultimate load of a structure given its equilibrium and strength conditions. In the deterministic case, the ultimate load is obtained through the resolution of a convex optimization program. When loading or strength properties are random, the data of such an optimization problem become uncertain. Robust optimization theory allows to compute a worst-case ultimate load estimate of such uncertain problems. We introduce the notion of robust strength criteria e.g. the robust counterpart ...
