FATIGUE PHENOMENA IN WELDED CONNECTIONS OF BRIDGES AND CRANES. TESTS OF BOX GIRDERS
Six box beams were tested in fatigue under four point repetitive loading. In three some eccentricity was applied to investigate effects of torsion. Welds corresponded closely to good practical quality, but small defects initiated failures, confirming earlier reports on the lowered fatigue resistance of large welds. Opportunity was taken to obtain further data on effects of stress concentration due to welded attachments outside the zone of maximum bending.
