• Abstract:
  Welded steel girder bridges can contain details that can high welding and service stresses and are termed constraint-induced fractures (CIF). The Kentucky Transportation Cabinet has steel bridges with weld details known to cause CIFs whose girders have experienced fracture events. The Cabinet’s bridge inventory was reviewed and additional candidate bridges with potential CIF details were identified. A review of bridge plans and pictures along with follow-up field investigations pinpointed bridges with CIF details that warrant up-close (i.e., arm’s length) inspections. Several uninspected bridges were identified as candidates for inspection to determine if they contain CIF details. Guidance is provided to help the Cabinet prioritize bridge inspections for CIF details and on repair actions for mitigating potentially problematic ones.
