The modeling and calculation of the proposed reinforced concrete slab using modern software systems are described. The description of the proposed reinforcement design is given. The results of the experiment on full-scale samples and the results of the calculation of the 3D model are shown. A comparative analysis of the data obtained during the experiment with the data obtained during modeling is performed.
