Deformation of intermediate zones of two-layers elements of reinforced concrete structures

Abstract

Analytical dependences are constructed for a characteristic reinforced concrete element simulating inter-medium contact zones with simultaneously occurring processes of changing the long-term strength of concrete in time, taking into account the aging process of concrete and the process of neutralizing concrete with an aggressive environment. The proposed version of the calculation model of the long-term deformation of a corrosion-damaged composite reinforced concrete element in the zone of contact of two concretes makes it possible to study the deformed state of such structures in a plane stress state.
