Outline of Final Research Achievements |
In this study, research on the application of fatigue resistance improvement using residual stress reduction by local heating, which was developed by the applicant, to welds of narrow structures in steel decks of highway bridges, was conducted in an international joint organization. The research was conducted in cooperation with Prof. Jarmai of the University of Miskolc, Hungary, on the optimization of the construction process and the approach from an economic viewpoint, which are useful for the practical application of this technology. The method to rationally evaluate fatigue durability was also studied in cooperation with Prof. Chang of Chung-Ang University, Seoul, Korea. The obtained results were submitted as international co-authored papers. In addition, we established a continuous cooperative system with the possibility of future development, such as the possibility of applying the method to different structures.
