This dissertation addresses the challenge of finding scalable frameworks for structural optimization under uncertainty. Therefore, efficient and non-intrusive formulations for the gradient computation of different Taylor series-based probabilistic methods are developed and a new probabilistic approach is presented. Additionally, challenges encountered by the multigrid finite element solver when dealing with (uncertain) anisotropic materials are discussed and a solution is presented.
