【 摘 要 】

The paper considers the development of an analytical model for long-term deformation of a reinforced concrete element with corrosion damage in plane stress state at the contact area between concretes of various grades on the basis of known stress-strain relations and parameters for reinforced concrete in a complex stress state with cracks. The derived flexibility matrix elements allow for taking into account long-term deformation, corrosion damage and shear in contact area between concretes of various grades. The authors give an example of a layered reinforced concrete beam calculation. The results of the calculation have been compared with an experimental study data.
