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

Cover Page

Abstract


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.
