| Research Abstract |
The steel corrosion on the boundary with concrete slab in steel truss bridges is reported. In this study, the specimens with H-shaped steel embedded in concrete imitated to the steel-concrete joint of truss bridge were damaged by corrosion to obtain the relationship of corrosion and damping factor. The forced vibration tests using vibration exciter were conducted. As the experimental results, it was shown that damping factor of steel members was gained by steel corrosion between steel and concrete boundary.
