• Summary:- The cases of fatigue damage, repair and retrofit applied are presented. The causes of fatigue damageare categorized as follows. (a) welding defects were remained during fabrication, (b) inappropriatestructural details of low fatigue strength were adopted, (c) stresses and deformations unforeseen indesign occurred at joints of members (d) structures behavior in a manner not expected, such as vibrationdue to wind. Case studies include girder bridges, orthotropic steel bridge decks, steel bridge pierstructures and others.
