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.
