Analysis of dynamic methods for calculating NPP building structures

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