An Expert System for Deterioration Assessment of Civil Engineering Steel Structures in Marine Environment

Abstract

Corrosion deterioration of civil engineering steel structures, such as steel pile piers and sheet pile walls in marine environments, has lately become of interest, and many unsolved problems on corrosion deterioration of the structures are now under investigation in various organizations.At first, we investigated the actual state of steel pile piers and sheet pile walls in port facilities, and developed a corrosion data-base of the structures. Next, we related the data-base to an expert system for corrosion deterioration assessment of the structures, which had some functions, such as stress check up, judgement of maintenance step, and life time prediction.In this paper, we described the data-base, and the outline of the whole advising system for corrosion deterioration assessment.
