Дана характеристика моделей и особенностей примененных материалов. Обоснован выбор расчетного комплекса. Выполнены численное моделирование и расчеты сталежелезобетонных балок. Моделирование выполнено в двух вариантах – без учета контактного взаимодействия стального сердечника с бетоном и с учетом контактного взаимодействия. Приведены результаты расчетов в числовом и графическом виде: нагрузки, соответствующие предельной несущей способности, вертикальные перемещения, ширина раскрытия трещин, высота сжатой зоны сечения. По всем параметрам проведены оценка и сравнение с экспериментальными данными. Выполнено сравнение характера разрушения численной и экспериментальных моделей. Дана оценка точности моделирования и правильности полученных результатов.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents a brief review of test experiments with models of steel-concrete beams made of high-strength concretes. The description is given to models and features of the applied materials. Numerical modeling and calculations are performed for steel-concrete beams. The modeling is performed in two versions: with and without the steel-concrete contact interaction. The calculation results are given numerically and graphically, and loads corresponding to the limiting bearing capacity, vertical displacements, crack opening width, height of the selected compressed zone are obtained. All parameters are evaluated and compared with the experimental data. Numerical and experimental models of destruction are compared. The obtained simulation and numerical results are compared.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бетон</kwd><kwd>сталь</kwd><kwd>железобетон</kwd><kwd>сталежелезобетонная конструкция</kwd><kwd>численные расчеты</kwd><kwd>контакт</kwd></kwd-group><kwd-group xml:lang="en"><kwd>steel-concrete interaction</kwd><kwd>reinforced concrete</kwd><kwd>composite steel</kwd><kwd>concrete structure</kwd><kwd>numerical simulation</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">Травуш В.И., Конин Д.В., Крылов А.С., Каприелов С.С., Чилин И.А.
