Influence of the corrosion damage scenarios on the residual life ofbridge grillages

摘要

Aim of the paper is the analysis of the behavior of a reference r.c. bridge grillage,rnrepresentative of a wide class of this structural typology, subjected to corrosion. Differentrndamage scenarios are analyzed and the most critical situation is highlighted. The analyses arernperformed with numerical procedures; the corrosion effects on the structural elements arerncalibrated on the basis of the results of experimental test carried out by some of the authors.
