Corrosion induced failures of post-tensioned bridges
Abstract
The present report includes the results obtained from a literature survey about corrosion-induced failures of post-tensioned bridges and a few other cases of prestressed structures. The structures have been briefly described with a focus on the prestressing system. After that, the failures have been characterized according to the severity of the observed damage, and attention has been given to the presence of warning signs. The major failure causes have been identified, with a subsequent in-depth analysis about the most frequent causes of corrosion. Finally, comparisons among the different typologies of investigated structures have been made
