The rationale for the chosen research topic is given. The description and features of experimental models of the studied structures, materials and their characteristics are presented. The features of the support and loading of the models are given. The analysis of the results of testing prisms for shear and models of composite steel and concrete beams and full-sized ofcomposite steel and concrete slabs for bending is carried out. The types and nature of the destruction of models are presented, a table of destructive loads is formed. Graphs of displacements and stresses in structural elements are given. The evaluation of the existing calculation methods, their comparison with the experimental results is given. An assessment of the effect of partial concreting of steel I-beams as part of prefabricated composite steel and concrete structure and its effect on the loadbearing capacity is given.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бетон</kwd><kwd>сталь</kwd><kwd>сталежелезобетонная конструкция</kwd><kwd>стержневая арматура</kwd><kwd>сборный элемент</kwd></kwd-group><kwd-group xml:lang="en"><kwd>concrete</kwd><kwd>steel</kwd><kwd>composite steel and concrete structure</kwd><kwd>bar reinforcement</kwd><kwd>precaststructure</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">Braun M.
