Reduction methods for the dynamic analysis of substructure models of lightweight building structures
Model order reduction was employed for models of lightweight building structures. Different reduction methods were compared in two numerical examples. Realistic boundary conditions are necessary when comparing reduced models. Conventional CMS is an efficient reduction method for the models considered. The Krylov subspace version of CMS was found to be a good alternative.
