Abstract: An analysis of the use of mesh, fiber and combined reinforcement is presented using the example of prism samples with modeling of structures of short columns with longitudinal reinforcement. Deformation diagrams, photo illustrations, and graphs characterizing the operation of samples under load are presented. The paper presents data from experimental studies to assess the effect of traditional indirect and fiber reinforcement on the stress-strain state of elements made of high-strength concrete under axial compression loading. Analytical expressions have been developed to evaluate the stress-strain state of elements with indirect mesh and fiber reinforcement. Numerical modeling of the stress-strain state of compressed elements using the finite element method (FEM) in the ANSYS Workbench 14.5 environment was carried out. It was found that taking into account the influence of physical nonlinearity of materials based on the proposed numerical dependencies provides higher accuracy in determining the bearing capacity and strain values of compressed reinforced concrete elements with indirect and fiber reinforcement.

Keywords: high-strength concrete, indirect and dispersed reinforcement, strength, deformation, experimental research, calculation.
