Review article

The article presents data on the results of modeling the strength properties of concrete under biaxial compression with tension. The model is developed on the basis of the analysis of the problems theory of percolation. The strength of the lattice nodes is determined by the results of unixial tests of concrete under compressive load. The elements of the structure are modeled by random variables distributed according to the normal distribution law. From the analysis of the model, there are presented the results indicating the influence of the order of applying the loads of different signs on the final results. The simulation results are compared with experimental data.
