4. Comparison of field tests with PC Lira calculations To carry out numerical studies of the performance of reinforced concrete structures made of high-strength, quick setting concrete, the PC Lira finite element modeling software complex was used. To solve the problem, two-dimensional and three-dimensional (volumetric) KE were used (Fig. 3).

Modeling of the experimental area was performed by volumetric physically-nonlinear finite elements of the PC Lira library No. 231 and 233, which were used to model the body of the plate, as well as finite element No. 10, i.e., a universal rod simulating a reinforcing mesh.
