Purpose: An analysis of the static load - carrying capacity of rectangular reinforced concrete deep beam taking into account the physical nonlinearities of structural materials: concrete and reinforcing steel, was the aim of the paper. Design/methodology/approach: The model of the elastic-perfectly plastic material was applied for the reinforcing steel. The reduced, static form of non-standard model of dynamic deformation, with regard to the material softening was applied for the concrete. The method of structure effort analysis was developed using the finite element method. Findings: The results of numerical solutions were presented with comparison to the experimental results and other numerical results taken from the literature. Very good agreement of the numerical results was obtained in comparison with the experimental results in the range of the load - carrying capacity and the displacement state analysis. Research limitations/implications: The effectiveness of the method analysis and computational algorithms for the problems of numerical simulation of reinforced concrete deep beam behaviour was indicated in the paper. Practical implications: The developed method can be applied to the effort analysis of the different reinforced concrete structural elements behaving in the complex stress states. Originality/value: The stress state in the deep beam was illustrated in the form of the stress distribution over the characteristic cross-sections as well as in the form of the scheme of the material effort on the surface of the structure.
