Annotation: The article analyzed the use of mesh and fiber reinforcement, as well as combined reinforcement. The samples are prism samples, some of it simulate the structures of short columns with longitudinal reinforcement. The article contains photographic illustrations and graphs characterizing the performance of samples under load, in particular deformation diagrams. The results of experimental studies of the influence of indirect and dispersed reinforcement on the strength and deformation of elements made of high-strength modified concrete under axial compression are presented. Analytical expressions are proposed to describe the strength and deformations of elements with indirect mesh and dispersed reinforcement. The author comes to the conclusion that taking into account the physical nonlinearity of the deformation of materials, according to the formulas given in the text of the article, allows us to reliably estimate the bearing capacity and deformations of compressed reinforced concrete elements with indirect mesh and dispersed reinforcement.
