[en] Corrosion of steel sheet piles in marine environment is a highly complex phenomenon, with a
high degree of uncertainty associated. The present model for prediction of corrosion in the Eurocodes (EN 1993-5), defines zones of different aggressiveness, and suggests values that depend on the temporal horizon of the structure. However, the model is made to be applied to any structure in marine environment, independently of the specific conditions that may be present in each case. This paper shows results of the application of a new multi-factorial model to predict corrosion to two sheet pile walls designed according to the Eurocodes in two different scenarios. The results show that in one of the situations, the level of safety of the sheet pile is below the acceptable limit of safety given by the Eurocodes. That suggests that the corrosion model of
EN 1993-5 must be applied with caution and with knowledge of its limitations.
