“…Corrosive damage to reinforced concrete elements can affect the strength of the material, change the design calculations, redistribute forces in the construction sections and disrupt the joint work of concrete with reinforcement, as well as lead to other consequences that reduce the deformation characteristics of reinforced concrete [3,4]. The most unfavorable result of the development of the corrosion process in reinforced concrete structures is the reduction of their bearing capacity and their suitability for operation, which leads to non-compliance with safety requirements and the limiting state at design loads [5].…”

The resistance properties of reinforced concrete and reinforcement, required for modeling the degradation and calculations of the durability of reinforced concrete elements under the conditions of various types of corrosion damage, based on analytical and experimental data are substantiated. A probabilistic model has been developed for predicting and estimating the durability and reliability of reinforced concrete elements, taking into account the statistical variability of the calculation parameters and the kinetics of degradation processes during long periods of operation. Methods are proposed for calculating and predicting the durability of reinforced concrete elements based on deterministic probabilistic models of degradation of structural elements operating under aggressive environmental influences.

Abstract.A new method for calculating reinforced concrete constructions of high-rise buildings under dynamic loads from wind, seismic, transport and equipment based on the initial assumptions of the modern phenomenological theory of a nonlinearly deformable elastic-creeping body is proposed. In the article examined the influence of reinforcement on the work of concrete in the conditions of triaxial stress-strain state, based on the compatibility of the deformation of concrete and reinforcement. Mathematical phenomenological equations have been obtained that make it possible to calculate the reinforced concrete elements working without and with cracks. A method for linearizing of these equations based on integral estimates is proposed, which provides the fixation of the vibro-creep processes in the considered period of time. Application of such a technique using the finite-difference method, step method and successive approximations will allow to find a numerical solution of the problem. Such an approach in the design of reinforced concrete constructions will allow not only more fully to take into account the real conditions of their work, revealing additional reserves of load capacity, but also to open additional opportunities for analysis and forecasting their functioning at various stages of operation.

“…The most common types of loads and sources of stress are factors like power, and nonviolent character: shrinkage and creep of layers; the loads caused during transportation and installation; constant operating load; foundation settlement; wind loads; vibrations and temperature difference between the concrete layers [8,9]. The monolithic cement matrix connecting layers in multilayer panels of different strength concretes provides transfer loads from the outer to the inner layer.…”
