In this study the existing degradation model for the coated steel member is reviewed, and a new model is recalculated with the deterioration index, ‘rusting’ and ‘flaking’ only. In the case of durability evaluation with the two indexes only some considerations are suggested by the comparison of the existing and recalculated degradation model.
