• Abstract:
  The latest edition of the AASHTO design specifications (AASHTO 2001) introduced provisions for fatigue design. However, many structures presently in service were designed before fatigue provisions were part of the design specifications. The fatigue design procedures now included in these specifications do not address the variability in fatigue life that is likely for structures in service, nor do these provisions allow engineers to quantify the risk of fatigue-induced fracture for structures that have been in service. As a result, Wisconsin undertook a research effort to assess the risk of fatigue-induced fracture in existing sign support structures that were designed before the latest AASHTO specification revisions.
