Introduction. The present article concerns the seismic performance of various building structures, including NPP objects. The provided materials generalize the results of the author’s longstanding work connected with the dynamics of building structures.Aim. To analyze the seismic performance of various building structures, including NPP objects, and represent the author’s material on the dynamics of building structures.Materials and methods. The presented materials include a definition of the dynamics concept, computational modeling of dynamic processes, main correlations of dynamic analysis methods, and a description of impacts (accelerograms). In addition, the concepts of resonance and vibration diagnostics in the dynamic analysis, assessment of the building strength and stability, as well as the description of applied software systems are provided. Some of the presented materials are characterized by the scientific novelty. The following methods were used in the study. The method of nonclassical modal superposition for determining the response of a structure under dynamic impacts together with floor response spectra were presented by the author at the ABAQUS (SIMULIA) International Conference in Barcelona, 2011. The essence of the method consists in the reliable account for a “soil” damper, modeling the energy outflow into the soil during the vibrations of a building, which ensures reliable results. A fundamental solution for accounting the ductility of the foundation slab under seismic impacts was applied. This method ensures the seismic response of the structure to be reliably determined, as well as the floor response spectra to be obtained in the conditions of the aircraft crashing for buildings, whose impact on the equipment is transmitted through the foundation slab. Additionally, the method of accounting the dynamic characteristics of building fragments (floor/ wall), obtained using the vibration diagnostic results, was applied to verify computational models, as well as to analyze the strength and floor response spectra. The appendix includes the realistic test problem of the seismic analysis, developed by the author.Results. The provided materials generalize the results of the author’s longstanding work in the field of NPP building structures. In addition to the scientific novelty, the materials are widely applied in the development of NPP designs both in the Russian Federation and abroad.Conclusion. The materials, presented in the article, can be used to prepare the “Introduction to Dynamics” lecture course, including, for newcomer countries that are at the beginning of the nuclear facility (NF) construction.
