Abstract
These alternative connections eliminated the backing bar, used high quality shop weld, and reduced the high stress and strain demand on the weld. Therefore, the failure of the bottom flange weld did not occur. However, for connections using the bottom girder flange component only, the inelastic mode of failure occurred at the top girder flange weld. Using the reduced flange plate at both the top girder flange and the bottom girder flange was the most effective method to develop large inelastic rotations of the joint with stable hysteretic behavior.
