Abstract: Deterioration of reinforced concrete infrastructure has emerged as one of the most demanding problems facing the building and construction industry worldwide. The principal cause of deterioration is corrosion of embedded steel reinforcement. The associated cracking and spalling of concrete cover, loss of steel bar cross sectional area and reduction in bond strength may severely impair structural integrity. To achieve realistic predictions of residual service life as well as safe and efficient rehabilitation and repair of structures attacked by corrosion, it is necessary to develop reliable methods for assessing the structural response of deteriorated and repaired concrete structures. The present paper describes a procedure for solving this problem based on nonlinear finite element analysis. Models representing the constitutive and kinematical behaviour of deteriorated concrete structures are presented together with a method for simulating the loading and straining history of reinforced concrete structures subjected to deterioration and subsequent repair. Numerical simulations are carried out in order to demonstrate the applicability and potential of the proposed method.
