• Abstract:
  The objective of this study was to build a model to assess the effects of removing and replacing a damaged concrete deck over prestressed concrete girders. The main research tasks included the following:• Review the literature on the deck removal process, prestressed concrete girders, prestress losses, and long-term deformations in concrete.• Survey engineers at state DOTs to document deck replacement practices in the United States.• Develop and validate a model to evaluate the long-term performance of a prestressed concrete girder, including the calculation of stresses/strains and camber/deflection throughout the service life.• Apply the model to a prestressed concrete girder bridge to illustrate the effects of deck replacement on bridge behavior.
