Cumulative damage study of highway bridges
Damage of highway bridges has become a serious problem nationwide. In this study, bridge damage is related to deterioration and/or distress which progress incrementally in stages. We use models that incorporate the Markov Chain concept to describe the cumulative damage of a bridge. Unfortunately, statistical data required for the damage increment are seldom available in most offices of the State Department of Transportation. However, bridge inspection reports are abundant. In these reports, bridge inspectors assess the conditions of the bridge components such as the bridge deck, superstructure, and substructure. They frequently use subjective notions in their ratings and descriptions of the component conditions. The concept of fuzzy set is used in this study to take advantage of these subjective judgements. The fuzzy operations result in fuzzy probability of component failures which is used to assess the cumulative damage of the bridge. A case study is presented to demonstrate the use of this method.
