• Abstract:
  Distortion-induced fatigue affects a large number of bridges within the US highway system. This type of damage is commonly observed at connections between cross frames and steel girders. The differential displacement induced by bridge traffic induces forces in the cross frames that cause out-of-plane distortion of the web, inducing highly localized stresses at the welds that tie the connection plate used to attach the cross frame to the girder.
