2. In the new structure, any fatigue cracks have not been developed at the connection between a trough rib and a cross rib, and a deck plate and trough ribs. The sufficient fatigue durability was confirmed. Furthermore, applicability of TRS to the field work was verified by trial eorks in the factory and actual bridges [Shinno (2018)].
