Up to the present, few studies have been made to develop the methods of coping
with inspection and repair of steel corrosion in non-painted weatherproof steel
structures. This is because it has been taken for granted that such structures
(using weatheproof steel) are maintenance-free. The purpose of this study is to
develop a new diagnostic system, which can forsee and detect prematurely the
corrosion degradation of non-painted steel structures. The present paper
introduces a new method to predict the volume of flying salinity from weather
data and geographical conditions. This method is simple and quite easy to implement
compared with conventional measurements. In addition, it is shown that future
corrosion weight loss in different parts of the structure members can be estimated
by measuring the corrosion rates of these parts. Finally, we show a new fundamental
system for diagnosing of corrosion degradation on non-painted weatherproof steel
structures.
