Abstract. A technique is proposed for calculating the durability of enclosing reinforced concrete constructions in the conditions of rheological deformation, taking into account the corrosion damage, reflecting their actual work under the joint action of the load and the aggressive medium, and also taking into account the random nature of the values ??accepted in the calculation. The possibility of considering the processes of prolonged deformation of reinforced concrete from the standpoint of a probabilistic approach to the destination of the design reliability coefficients for the load and for the material is shown. An illustrative example is given for calculating reinforced concrete shallow shell under joint action of a snow load and a load of its own weight for different periods of operation.
Key words: corrosive damage of concrete; reinforced concrete structures; durability of shallow shells.
