Abstract
This article discusses the issues of numerical study of the strength and crack resistance of member bending elements based on a nonlinear deformation model. The operation of reinforced concrete elements at different levels of loading is analyzed, the processes of crack formation and development are investigated, as well as the influence of the deformation characteristics of materials on the overall bearing capacity of structures. The article discusses the features of the use of nonlinear models for the calculation of bending elements and their correspondence to experimental data. The study shows the importance of accurate accounting of real diagrams of the state of concrete and reinforcement, as well as the need to improve numerical methods to increase the reliability of calculations and ensure the safety of building structures.
