Long-Term Exploitation of a Reinforced Concrete Beam on a Ground Base with Corrosion Damage
Abstract
An estimated estimate of the long-term operation of a reinforced concrete beam on a ground base is presented, taking into account environmental and dynamic force effects. A method of dynamic calculation of reinforced concrete structures of structures of various types on a ground base operated in an aggressive environment is proposed, internal factors of rheological deformation are also taken into account, taking into account corrosion damage, reflecting their real work under the joint action of the load and the aggressive environment on the basis of the modern phenomenological theory of deformation of the elastic creeping body. It is shown that corrosion damage to reinforced concrete elements can affect the strength of the material, change the calculation schemes, redistribute forces in the cross-sections of the structure and disrupt the joint operation of concrete with reinforcement, as well as lead to other consequences that reduce the design time of operation of structures and other operational characteristics. The possibility of modeling the processes of deformation of reinforced concrete under conditions of long-term operation with a changing mode of action of an external load is shown. An example of the calculation of a reinforced concrete flexible foundation on a soil base is given for the considered service life and the presence of corrosion damage.
