Probable Approach to the Estimation of the Durability of Reinforced Concrete Structures

Abstract

A method for calculating the durability of reinforced concrete structures under conditions of rheological deformation, taking into account corrosion damage, is presented, reflecting their real work under the combined effect of the load and aggressive environment, and also t the random nature of the effects. The possibility of considering the processes of long-term deformation of reinforced concrete from the standpoint of a probabilistic approach to the designation of the calculated reliability coefficients for the load and the material is shown. The regularity of the change in the maximum bending moment at different lifetimes is given, taking into account the rheological properties of materials by the example of the coating shell.
