Развитие вычислительной техники и программных комплексов даёт этому направлению новый этап развития – применение численных моделей в повседневном проектировании. Для более широкого использования численных моделей и обеспечения сопоставимости результатов важно выработать универсальные принципы построения численных моделей с последующей регламентацией в нормативных документах. В рамках данного исследования сделан акцент на применении численных моделей наравне с классическими (формульными) моделями, и в первую очередь для этого выполнен обзор и систематизация наиболее важных параметров численных моделей несущей способности. Представлены указания по назначению свойств материалов, типа конечного элемента, качества сетки, величины и формы несовершенств применительно к стальным конструкциям. Полученные результаты представляют интерес для дальнейших исследований по унификации требований к параметрам численных моделей и их верификации на основании экспериментальных данных с вычислением статистических характеристик неопределённости численной модели.</p></abstract><trans-abstract xml:lang="en"><p>The use of numerical models to analyze the behavior of steel elements has undeniable advantages and opens up a number of promising areas for the study of complex or new design solutions. The development of computer technology and software gives this direction a new stage of development - the use of numerical models in everyday design. For wider use of numerical models and ensuring comparability of results, it is important to develop universal principles for constructing numerical models with subsequent regulation in normative documents. Within the framework of this study, emphasis is placed on the use of numerical models on a par with classical (formula) models, and first of all, for this purpose, a review and systematization of the most important parameters of numerical models of load-bearing capacity is carried out. The instructions on the purpose of the properties of materials, the type of the final element, the quality of the mesh, the size and shape of imperfections applied to steel structures are presented. The results obtained are of interest for further research on the unification of the requirements for the parameters of numerical models and their verification based on experimental data with the calculation of statistical characteristics of the uncertainty of the numerical model.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>численная модель несущей способности</kwd><kwd>стальные конструкции</kwd><kwd>неопределённость</kwd><kwd>метод конечных элементов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>numerical model of load-bearing capacity</kwd><kwd>steel structures</kwd><kwd>uncertainty</kwd><kwd>finite element method</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">Graciano C., Ayestarán A.
