the technique of calculation of the reinforced concrete element exposed to the aggressive environment is considered, the quantitative reduction estimation of power resistance of concrete and armature is given.

This work is devoted to the methodology for calculating the compressed reinforced concrete elements under dynamic loading, which takes into account the lack of adhesion of tensile reinforcement to concrete. As experiments have shown, the lack of adhesion between concrete and reinforcement leads not only to a decrease in the bearing capacity, but also to a qualitative change in the strain diagrams’ shape in the sections. The calculations according to the current regulatory documents do not take into account the fact that the reinforcement does not adhere to concrete, as a result, it is difficult to determine the actual bearing capacity of the element. The dynamic impact of loads adds complexity to these types of calculations. This approach makes it possible to perform the calculation in the elastic, elastoplastic and plastic stages of work, while taking into account the absence of reinforcement adhesion with concrete in determining the height of the concrete compressed zone.
