Periodic two- and three-dimensional structural models designated for rectangular-plan buildings are considered in the article. Expressions for identification of natural frequencies designated for unloaded and loaded two-dimensional structural models, as well as non-free three-dimensional structural models of multistoried buildings are provided in the article.
