USER PARTICIPATION TYPE DATABASE OF REPAIR CASES ON FATIGUE FAILURES

Abstract

 Approximately 200 repair cases of failed steel bridges owing to fatigue are summarized into an Internet based database. Since the basic system that this database uses is PukiWki, which is a Wiki-type content management system, any users can participate in creating the database, as in Wikipedia. Further, causes of failures, repair methods, service years and occurrence of cracks, and types of welding defects are analyzed using the cases included in this database. In this paper, firstly, the system of the database is introduced. Next, the results of the analyses are presented.
