dc.description.abstract | This study was based on findings from the Norwegian Public Roads Administration's
Bridge Management System and field investigations on corrosion damage in
pretensioned Norwegian standard I-beam (NIB) girders in 227 coastal climate bridges.
The main durability design parameters are summarized and related to regulations
over the last 80 years. Environmental exposure is discussed in the light of the
global, local, and micro climate. We found that 51% of the bridges have girder corrosion
damage. The percentage is highest for bridges built when the cover thickness
required was lowest. Cover thickness below that required (resulting from
production faults) caused 74% of corrosion damage. Most of the severe chlorideinduced
corrosion damage in bridges was found in the inner NIB girders, particularly
in the support-zones and their vicinity. This can be due to interaction between
geometry and exposure. Corrosion of reinforcement in support-zones can impact
structural behavior, particularly NIB girder shear performance. | en |
