    • Abstract:
      A pilot project was initiated to assess the performance of the HPS bridge members as well as to evaluate

      the response of the structure to actual traffic and environmental loads under in-service conditions

      through monitoring of strain, temperature and displacement. Monitoring of an actual bridge provided

      an opportunity to validate the laboratory values obtained in the earlier study and supply WisDOT with

      additional tools to evaluate the specifications for design and construction of bridges using HPS. Both

      AASHTO’s standard specifications for bridge design and the recently implemented Load and Resistance

      Factor Design specifications, or LRFD, assume the use of non-HPS steels. This pilot project and

      related research provided a case study to assess the impact on these design methods of using a material

      with improved properties.
