| Abstrait: |
This paper gives an overview on research realized for orthotropic steel bridge decks, especially considering longitudinal Y-stiffeners. In a running research project fatigue cracks observed at existing bridges with Y-stiffeners were documented together with the original shop drawings based on literature and personal research. Furthermore, existing methods of repairing of cracks between stiffener and crossbeam have been summarized. Promising innovative methods of maintenance were identified and fatigue tests on these details and their repairing methods were realized. Thereby, the construction detail in the original condition and the construction detail in the repaired condition are tested and compared to each other in order to estimate the effectiveness of the maintenance method. First results of this running research program are presented. |
