Many highway bridges in the United States are in a deteriorating                condition as a result of aging, environmental effects, and inadequate           strength for today's heavy loads.  To extend the remaining life of some         of the bridges it is possible to strengthen them by various methods.            This project will investigate the feasibility of strengthening steel            bridge girders by prestressing the girder to increase its load                  supporting capabilities.  This project follows a previous project which         is investigating the static strength, ductility, reliability and                load-deflection characteristics of the strengthened composite steel             girder.  The emphasis for this phase of the investigation will focus on         the fatigue strength of the strengthened composite steel girders.
