Atmospheric corrosion is a commonly observed cause of deterioration in metallic structures,such as steel railway bridges.The progression of corrosion damage can lead to inadequate performance and reduced safety,which ultimately can result in structural failures (e.g.Wardhana & Hadipriono 2003,Imam &Chryssanthopoulos 2012).In simple terms,corrosion can be classified as a general or local,though a more precise classification based on the forms of corrosion can also be relevant (e.g.Landolfo et al.2010):general (uniform),pitting (localised),crevice,erosion,galvanic and fatigue corrosion.It is important to point out that during different time stages,a localised form can spread spatially or,conversely,a uniform domain can develop localised patterns.
