Abstract |
In recent years, many infrastructure have been rapidly aging around the world, which grows interest in the maintenance of theinfrastructure. Among the social infrastructure, bridge is a very important structure to transport lots of human and various products. Theperformance evaluation of bridge can be divided into the condition evaluation and safety evaluation, proposed by Korea Infrastructure Safety andTechnology Corporation. However, there are no separate criteria for the performance evaluation of three-class bridges. In general, the performanceof bridge is dominated by the results of the condition evaluation, which is lower than that of the safety evaluation. Therefore, this study assessed thecorrelation between the condition evaluation of superstructure and bridge and also between the condition evaluation and the safety andload-carrying capacity of bridge. The results of the study would provide a basic data for the more quantitative and higher relevant performanceevaluation of the existing bridges, particularly for three-class bridges.
