The paper presents an analysis of the deformation of a dynamically loaded rectangularreinforced-concrete deep beam, including the physical nonlinearity of construction materials: concreteand reinforcing steel. The solution was acquired with the use of the method presented in [15]. Thedisplacement of three plate types under various loads, up to dynamic load capacity depletion, wasanalysed. The results of numerical solutions are presented, with particular emphasis on the impactof the very high strength of concrete and steel on the reinforced concrete plate displacement. Thework confirmed the correctness of the assumptions and deformation models of concrete and steelas well as the effectiveness of the methods of analysis proposed in the paper [1, 15] for the problemsof numerical simulation of the behaviour of reinforced concrete deep beams under dynamic loads.Keywords: mechanics of structures, reinforced concrete structures, deep beams, dynamic load,physical nonlinearity.
