Abstract
The article presents both a methodology and results of experimental studies, also finite element analysis of the stress-strain state of reinforced concrete slab, which is part of the steel and concrete composite cable space frame. As a result of the tests, the magnitude of the destructive load was set, for each individual sample it was different and was in the range 45-47 kN. The nature of destruction of experimental samples is established. For simulation of physical and mechanical properties and boundary conditions, the results of experimental studies were applied. Creation of finite-element models of reinforced concrete slabs was carried out on the basis of a preliminary study, the purpose of which was to determine the optimal size of the finite element. As a result of the analysis, it was found that the distribution of stresses in the plate completely corresponds to the experimental data. A comparison of the experimental and numerical data was performed. The average difference of the results did not exceed 7%.
