Long-Term Exploitation of a Flexible Foundation in Conditions of Nonlinear Rheological Deformation under Force and Non-Force Influences

A method is proposed for calculating a reinforced concrete flexible foundation on a soil base in an aggressive environment under rheological deformation conditions, taking into account corrosion damage, reflecting its real operation under the combined influence of force and non-force influences based on the modern phenomenological theory of deformation of an elastic creeping body. The possibility of considering the processes of long-term deformation of rein-forced concrete under a changing mode of action of an external load based on the method of integral estimates is shown. It is shown that environmental damage to reinforced concrete structures can affect the strength of the material, change the calculation schemes, redistribute efforts in the sections of the structure and also lead to other consequences that reduce the design life of buildings. An example of the calculation of a reinforced concrete flexible foundation of a residential building on a soil base is given, taking into account the friction forces along its sole at various periods of service life and the presence of corrosion damage.
