Research on Cracks Caused by Nonlinear Deformation of a Reinforced Concrete Slab

The article develops a software package based on a calculation method for cracks caused by nonlinear deformations in reinforced concrete slabs with discontinuous parameters. The system’s functionality is based on a mathematical apparatus for modeling cracks in reinforced concrete slabs. The subsystem is presented as a package of problem-oriented procedures for determining the Stress-Strain State (SSS), along with a subsystem of mathematical and software algorithms for SSS determination, which is housed in a library of load modules. The subsystem software consists of a package of applied software modules that perform specific mathematical and logical functions. A new method for calculating the deformation and stability of plates with discontinuous-parameter cracks has been developed. Based on this method, calculation results for specific problems have been obtained. The effectiveness of the method lies in the use of a standard set of approximating functions at each loading stage; these functions represent solutions to linear problems and can be constructed using any known calculation methods.
