Abstract

Many severe corrosion damages have been observed in steel structures constructed in a period of high economic growth. To ensure the safety of such structures, it is important to devise a method how corrosion develops in the service. In our research, semi-variogram analyses were carried out on time-dependent corrosion surfaces of unpainted steel plates exposed to atmospheric environment in order to quantitatively clarify the spatial autocorrelation structures and their time-dependence. In addition, by using the spatial statistics and an ordinary kriging technique, numerical simulation for the time-dependent corrosion surfaces in atmospheric environments was proposed and the validity was confirmed by comparing with corrosion surfaces obtained in various exposure fields.
