Abstract
One of the most important parameters for the modelling of the structural behavior and the service life of structures that are exposed to chloride-induced corrosion is the morphology of the corrosion attack. The depth of a corrosion pit, its extent along the circumference of the steel cross-section and in longitudinal direction greatly influence the load-deformation behaviour of a structure. Today, researchers are aware of the diverse shapes of corrosion pits, but there is no statistical data that could be used as an input parameter for their models. This results in large uncertainties in the analysis of the load-deformation behaviour of corroded structures. Therefore, we present a practical approach for the data collection on-site and the subsequent analysis.
