Replacement of the foundations is expensive and often unnecessary if the new bridge superstructure is lighter than the old one. With stricter design guidelines being in effect nowadays, a conventional orthotropic steel deck design will end up being heavier. A lightweight fiber reinforced polymer deck supported by steel girders is proposed as a solution. In this thesis the potential mass reduction resulting from a lightweight FRP deck is analyzed. Analyses are initially performed under the assumption that realizing composite action will generate the best results.
