STUDIES OF FATIGUE DAMAGES BASED ON STRAIN MEASUREMENTS OF A HIGHWAY BRIDGE

The strain behavior at the connection plate between main girder and transverse bracing in a simply supported composite plate girder is studied in order to find the causes of fatigue cracks. These cracks occur mainly at the upper end of stiffening plates and rib plates for connection, and propagate into the web plates of main girders. The strains measured in field tests are analyzed and fatigue investigations are carried out using Miner's Law. As the result, it is clear that cracks are initiated by cyclic high stress due to unequal deflection of main girders and deformation of slab plate at the front toe of fillet welds between flange plate and stiffener or rib.
