Bridge Maintenance Level Assessment

Abstract: Parameters in assessing the effectiveness of maintenance tasks on the overall cost of a bridge or system of bridges are identified and the linkage among maintenance, condition rating, and cost is made by subdividing the subjective process into smaller parts. Experience with New York City bridges is used to develop a life expectancy model once the maintenance and repair protocol is specified. Results for several sample maintenance allocations are given to show how a rapid spreadsheet calculation can provide a b… Show more

“…However, the numbers of experts and senior engineers are insufficient in the area of maintenance of bridge; for that reason, how to translate tacit experience to explicit knowledge becomes a major problem in bridge maintenance (Gattulli and Chiaramonte 2005;Miyamoto et al 2000;Testa 2002;Wang and Elhag 2008).…”

“…There are many different ways such as pairwise comparison matrix method (or called AHP or Eigenvector method) (Saaty, 1998), Delphi method (Chang, Huang, & Lin, 2000;Curtis, 2004), and so on, which can all be used to determine the relative weights of the identified bridge factors. Table 2 shows the relative weights of the 13 identified bridge factors used in New York bridge management system (BMS) (Testa & Yanev, 2002;Yanev, 1998).…”

“…Each component is assigned a rating R i on the scale of 1-7 during inspection and contributes to overall bridge rating R through a weight w i , which varies from component to component and from one system to another. The overall bridge condition rating is given by (Testa & Yanev, 2002;Yanev, 1998) Melhem (1994) presented a fuzzy inference model for bridge condition rating, in which bridge condition ratings were given on a scale of 0-9 and were all considered as fuzzy numbers. The pairwise comparison matrix and eigenvector method were used to determine the priorities among bridge elements, and the fuzzy multiple attribute decision making technique was utilized to synthesize the ratings of bridge elements and to generate an overall assessment for each bridge component such as deck, superstructure and substructure.…”

“…Appropriate maintenance and rehabilitation actions need to be planned and implemented throughout the lifecycle of the structure in order to maintain its adequate performance [4]. Rehabilitation actions should be initiated when performance of a structure falls below a pre-defined acceptable level [5]. The scope and type of these actions should be based on the current status of the structure, on the trends identified in recent past, as well as on predictions of the type and rate of future deterioration.…”
