Abstract
Indirect reinforcement is one of the effective ways to increase the strength and deformation characteristics, which is achieved by creating a volumetric stress state in concrete. For the design of reinforced concrete structures with indirect reinforcement, the calculation method based on a nonlinear deformation model is well suited. For such calculations, it is required to construct the stress-strain diagram, which will most accurately describe the relationship σ-ε. The article presents a numerical analysis of increasing the bearing capacity and deformations of concrete of various classes with indirect reinforcement in the form of welded meshes. Selected formulas to determine strength and ultimate compressibility. The problems arising in determining the compressibility limit of concrete with indirect reinforcement for engineering calculations are noted. Recommendations for calculating the parametric points of the stress-strain diagram are given.
