Определение несущей способности сжатых колонн при комбинированном воздействии (эксплуатационном статическом и поперечном динамическом загружении), в том числе при аварийных нагрузках с учетом фактического состояния в условиях воздействия различных коррозионных и других средовых воздействий, является актуальной, недостаточно изученной проблемой. Ее решение требует разработки аналитических методов, трудоемких конечно-элементных моделей (КЭМ), рассмотрения и учета значительного количества параметров конструкции и среды.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Решение задачи получено аналитическим методом. Для оценки его корректности разработана КЭМ в объемной постановке, выполнено сравнение полученных аналитических результатов с экспериментальными данными других авторов.</p></sec><sec><title>Результаты</title><p>Результаты. Разработана инженерная методика приближенной оценки несущей способности центрально сжатых поврежденных коррозией железобетонных колонн при поперечной импульсной нагрузке, вызванной аварийными ситуациями. Проведено сравнение результатов расчета с результатами конечно-элементного моделирования и известных натурных экспериментов для конкретной схемы закрепления колонны. Предложена дискретно-временная модель учета коррозионных повреждений для объемных конечно-элементных схем, основанная на параболическом законе снижения механических характеристик бетона по глубине распространения коррозии.</p></sec><sec><title>Выводы</title><p>Выводы. Установлено, что увеличение коррозионных повреждений бетона приводит к его хрупкому разрушению при аварийном воздействии, а увеличение глубины коррозионных повреждений при значительных сжимающих нагрузках ведет к местной потере устойчивости стержней арматуры в зоне действия поперечного импульса и существенному снижению сопротивляемости колонны прогрессирующему разрушению. Показана применимость предложенной инженерной методики к практическому использованию в интервале фактических эксплуатационных нагрузок.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Finding the bearing capacity of compressed columns subjected to a combination of effects (normal static and transverse dynamic loading), including emergencies and taking into account the actual condition under various corrosion and other environmental effects, is a relevant though understudied problem. It requires analytical methods, labor-intensive finite element models, and a great number of parameters that should be taken into account.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The solution was obtained analytically. The finite element model was developed in a 3D formulation to evaluate the applicability and convergence of results. Analytical results were compared with those obtained experimentally.</p></sec><sec><title>Results</title><p>Results. An analytical technique was developed for the approximate evaluation of the bearing capacity of centrally compressed corrosion-affected reinforced concrete columns under transverse impulse loading in an emergency situation. The results obtained analytically were compared with the results of finite element modeling and well-known full-scale experiments that involved a specific column attachment pattern. A discrete-time model is proposed to take into account corrosion damage in 3D finite element schemes. This model is based on the parabolic law of mechanical characteristics of concrete that deteriorate along with the depth of corrosion propagation.</p></sec><sec><title>Conclusions</title><p>Conclusions. The authors found that a greater corrosion damage to concrete leads to its non-plastic destruction in the case of exposure to emergencies, and deeper corrosion damage under great compressive loading leads to the local loss of stability of reinforcement bars in the zone affected by transverse impulse loading and a great reduction in the column resistance to progressive collapse. The practical applicability of the proposed engineering method is proved for the range of relevant values of compressive loads.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>механическая безопасность</kwd><kwd>железобетонные колонны</kwd><kwd>центрально сжатые элементы</kwd><kwd>динамические нагрузки</kwd><kwd>ударное воздействие</kwd><kwd>поперечный удар</kwd><kwd>коррозионные повреждения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mechanical safety</kwd><kwd>reinforced concrete columns</kwd><kwd>axially-loaded elements</kwd><kwd>dynamic loads</kwd><kwd>impact loading</kwd><kwd>transverse impact</kwd><kwd>corrosion damage</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы благодарят рецензентов за работу, направленную на улучшение качества статьи.</funding-statement><funding-statement xml:lang="en">The authors thank the reviewers for their efforts focused on improving the quality of the article.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Daneshvar K., Moradi M.J., Ahmadi K., Mahdavi G., Hariri-Ardebili M.A. Dynamic Behavior of Corroded RC Slabs with Macro-Level Stochastic Finite Element Simulations // Engineering Structures. 2021.
