При этом применяют основные принципы макромоделирования, в соответствии с которыми упругое поведение конструктивной системы обусловлено работой линейно-упругих стержней и пластин, а нелинейное поведение полностью определяется поведением точечных и/или линейных пластических шарниров. Таким образом, адекватное описание диаграмм для пластических шарниров представляет собой важный элемент моделирования. В статье представлены предложения по описанию параметрических точек пластических шарниров изгиба, среза и осевого растяжения, что позволяет описать работу повреждённой конструктивной системы на всех стадиях её работы. Предложено выполнять ограничение предельных углов поворота при изгибе с учётом критерия разрушения при срезе. Выполнено сравнение результатов расчёта, полученных с применением имитационной конечно-элементной модели с опытными данными.</p></abstract><trans-abstract xml:lang="en"><p>In modern design practice, a numerical method for verifying the robustness of damaged structural systems based on imitation modeling is becoming increasingly common. This method utilizes the fundamental principles of macromodeling, according to which the elastic behavior of a structural system is determined by the operation of linearly elastic rods and plates, while nonlinear behavior is completely determined by the behavior of point and/or linear plastic hinges. Thus, an adequate description of the diagrams for plastic hinges is an important element of modeling. This article presents proposals for describing the parametric points of plastic hinges for bending, shear, and axial tension, which allows for describing the operation of a damaged structural system at all stages of its operation. It is proposed to limit the maximum rotation angles during bending, taking into account the shear failure criterion. The calculation results obtained using an imitation finite element model are compared with experimental data.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>численный анализ</kwd><kwd>повреждённая конструктивная система</kwd><kwd>имитационное моделирование</kwd><kwd>пластический шарнир</kwd></kwd-group><kwd-group xml:lang="en"><kwd>numerical modeling</kwd><kwd>damaged structural system</kwd><kwd>imitation modeling</kwd><kwd>plastic hinge</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">Живучесть зданий при особых воздействиях: монография [В.И.
