Development of a knowledge-based system for condition assessment of bridges

摘要

Condition assessment of reinforced concrete (RC) bridges is a complex subject. The complexity arises from a variety and combination of factors that define the condition of an existing bridge. A thorough condition assessment requires vast knowledge of the behaviour of RC structures subjected to different phenomena such as excessive loading, environmental effects, chemical attacks, etc. This requirement can be achieved through a comprehensive knowledge-based system, which may represent human expertise. Presently, the Public Works Department (JKR), Malaysia has a condition assessment system, which is based on visual inspection. A comprehensive system requires an input not only from visual inspection but also from that of confirmatory non-destructive tests and distress investigations, through structural analysis. This paper describes development of a comprehensive expert system that integrates the present system adopted by JKR with those of non-destructive test results and distress analysis.
