The paper presents experimental and numerical studies to determine the main characteristics of bent reinforced concrete precast slabs. We tested 45 reinforced concrete slabs with a constant load, in a specially made steel stand. The main purpose of the test is to study the effect of the thickness and percentage of reinforcement of slabs on strength and deformability. The zone of a slab with a constant moment was studied. It was revealed that slabs with a thickness 120 mm showed a more brittle fracture similar to the destruction of compressed concrete elements, while thin plates 80 mm collapsed in a quieter nature. As a result of numerical and experimental analyses, it was found that the use of B600B steel allows for more economical use of reinforcing steel. In the experimental research, a diagnostic systemfor measuring displacements and strains was used, which can be easily implemented in the conditions of use of the real structure. The obtained experimental results were compared with the results obtained from the analysis of the numerical model.
