Abstract: This article is devoted to the study of the work of reinforced concrete summer beam structures under conditions of action of cyclic loads with high levels. The authors found that studies on the development of physical models of atomic resistance of bending reinforced concrete elements, cyclic effect of lateral forces and the methods of calculation on their basis are important and appropriate due to certain features and essential specificity of the mentioned type of load. These primarily include nonlinearity of deformation, damage accumulation in the form of fatigue micro- and macro-cracks, fatigue construction materials destruction and so on. At work key expressions determining the limits of endurance of concrete, longitudinal reinforcement, anchoring longitudinal reinforcement, which create the endurance throughout the whole construction, are mentioned. Equally important, as noted in the present article is to establish the link between tensions and deformations element in these conditions because there is a presence of cyclic stress-induced creeps’ deformations.
