Shape design of arch dams under load uncertainties with robust optimization

Fengjie TAN, Tom LAHMER

Frontiers of Structural and Civil Engineering 2019, Volume 13, Issue 4,   Pages 852-862 doi: 10.1007/s11709-019-0522-x

Abstract: The focus of this paper is on the non-probabilistic-based design of new arch-type dams by applying meansof robust design optimization (RDO).The optimization of an arch-type dam is realized here by a robust optimization method under load uncertaintyThe load uncertainty is modeled as an ellipsoidal expression.By this means, the robust design can generate an improved arch dam structure that ensures both safety
