• Abstract:
  A fitness-for-purpose evaluation was performed on the electro-slag flange welds of the West Fremont bridge approach ; superstructures, per the request of FHWA. This evaluation required gathering knowledge of the material properties, fabrication ; defects and service loads pertaining to the weldments in question. The serviceability of the weldments was assessed based on the ; fatigue and fracture performance. It was concluded that the welds have sufficient toughness and fatigue resistance to remain in ; service with no retrofitting.
