Исследуется сопротивление железобетонных изгибаемых элементов с соединением арматуры внахлест при динамическом нагружении в условиях аварийной расчетной ситуации. Выполнено численное моделирование конструкций железобетонных балок по методу конечных элементов в физически нелинейной трехмерной постановке с учетом параметров диаграммы сцепления арматуры с бетоном. На основе результатов численного моделирования выполнена количественная оценка влияния соединения продольной арматуры внахлест на несущую способность и деформативность железобетонных изгибаемых элементов при динамическом воздействии, возникающем в аварийной расчетной ситуации. Установлено, что предельная статическая нагрузка, определенная из условий энергетического баланса, составила 0,87 от уровня разрушающей нагрузки как для изгибаемого элемента с наличием соединения продольной арматуры внахлест, так и для элемента со сплошными стержнями арматуры на всю длину. При этом соотношение между полными и условно упругими деформациями оказалось больше на 13,4 % для конструкции с наличием соединения арматуры.</p></abstract><trans-abstract xml:lang="en"><p>Longitudinal reinforcement couplings, and particularly overlap-coupling, have various levels of ductility. This can influence the response parameters of reinforced concrete structures under dynamic loading by means of changes in the deformability of structures. The study investigates the resistance of reinforced concrete flexural members with overlap reinforcement coupling under dynamic loading in accidental design situations. It provides numerical modeling of reinforced concrete beams using the finite element method in a physically nonlinear three-dimensional formulation, taking into account the parameters of the bond-slip diagram. Based on the results of numerical modeling, the influence of longitudinal reinforcement overlaps couplings on the load-bearing capacity and ductility of reinforced concrete flexural members under dynamic loading arising in an accidental design situation has been assessed. It was established that the ultimate static load, determined based on energy balance, was 0.87 of the failure loads for both the flexural member with overlapping longitudinal reinforcement and the member with continuous reinforcement bars along its entire length. At the same time, the ratio between total and conventionally elastic deformations was 13.4 % higher for the structure with reinforcement coupling.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>прогрессирующее обрушение</kwd><kwd>соединение арматуры</kwd><kwd>нахлест</kwd><kwd>несущая способность</kwd><kwd>деформативность</kwd><kwd>железобетон</kwd><kwd>изгибаемый элемент</kwd></kwd-group><kwd-group xml:lang="en"><kwd>progressive collapse</kwd><kwd>reinforcement coupling</kwd><kwd>overlapping</kwd><kwd>load-bearing capacity</kwd><kwd>ductility</kwd><kwd>reinforced concrete</kwd><kwd>flexural member</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">Колчунов В.И. и др.
