Sammendrag
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.
