Advances in the study of prestressed precast beams include the response of existing structures undergoing deterioration. The paper describes the behaviour of corroding prestressed structures, presenting a review of experimental results on the effects of corrosion on the prestressing reinforcement and the bond of corroded 7-wire strands in concrete. A numerical finite element model for the structural response of beams is set up, using the information gained from the tests to analyse the corrosion effects and to calibrate the model parameters.

Abstract
Advances in the study of prestressed precast beams include the response of existing structures undergoing deterioration. The paper describes the behaviour of corroding prestressed structures, presenting a review of experimental results on the effects of corrosion on the prestressing reinforcement and the bond of corroded 7-wire strands in concrete. A numerical finite element model for the structural response of beams is set up, using the information gained from the tests to analyse the corrosion effects and to calibrate the model parameters. The results provide indication for the assessment of structures deteriorating in the field.File | Dimensione | Formato | |
