Participatory database of repair cases on fatigue damaged welded structures

We report a Web database in which 204 fatigue-related steel bridge repair cases have been summarized. Since the database is based on the PukiWiki system, which is a Wiki-type content management arrangement, any user can participate in creating and modifying database files, much as is commonly done in Wikipedia. Furthermore, failures causes, repair methods, service years, crack occurrences, and welding defect types are analyzed using the cases included in this database. In this paper, we introduce the database and present the results of the analyses.
