В особенности это касается сжатых и сжато изгибаемых элементов, в том числе колонн зданий. Здания со значительным периодом эксплуатации накапливают коррозионные повреждения, которые приводят к местной деградации механических характеристик материалов, что может существенно сказаться на предельной несущей способности и живучести конструктивных систем в целом при динамических воздействиях. Разрабатывается подход к определению прочности нормальных сечений для внецентренно сжатых колонн в случае малого начального эксцентриситета при поперечном ударе. Коррозия рассматривается в виде «точечного» очага, в пределах которого могут быть деградированы механические характеристики как бетона, так и арматуры. Степень деградации механических характеристик материалов определяется по экспериментальным данным, получаемым на основе схем ускоренной коррозии. В зависимости от ее степени учитывается влияние стеснения деформаций бетона в направлении, перпендикулярном сжатию. Приводится верификационное сравнение разработанной методики с экспериментальными данными динамических испытаний колонн при поперечном ударе. Рассмотрен пример расчета коррозионно-поврежденной колонны.</p></abstract><trans-abstract xml:lang="en"><p>The issues of the robustness of load-bearing structures under technogenic emergency impacts are currently becoming increasingly relevant in both domestic and global structural engineering. This is particularly true for compressed and compression-bent elements, including building columns. Buildings with a significant service life accumulate corrosion damage, which leads to local degradation of the mechanical properties of materials. This can substantially affect the ultimate load-bearing capacity and overall robustness of structural systems under dynamic loads. An approach is being developed to determine the strength of normal sections for eccentrically compressed columns with a small initial eccentricity under transverse impact. Corrosion is considered as a localized "spot" defect, within which the mechanical properties of both concrete and reinforcement may be degraded. The degree of degradation of the materials' mechanical properties is determined from experimental data obtained using accelerated corrosion schemes. Depending on the degree of corrosion, the effect of confinement on concrete deformations in the direction perpendicular to compression is taken into account. A verification comparison of the developed methodology with experimental data from dynamic tests of columns under transverse impact is provided. A calculation example for a corrosion-damaged column is considered.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>поперечный удар</kwd><kwd>коррозионные повреждения</kwd><kwd>железобетонные конструкции</kwd><kwd>колонна</kwd><kwd>динамические воздействия</kwd><kwd>механическая безопасность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>transverse impact</kwd><kwd>corrosion damage</kwd><kwd>reinforced concrete structures</kwd><kwd>column</kwd><kwd>dynamic loads</kwd><kwd>structural safety</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Tamrazyan, A.
