Abstract
Many of the old truss bridges in New York State are restricted to legal loads due to deterioration, increased dead loads due to the addition of overlays, and increased live loads, which are larger than that allowed in the past. By replacing the heavy decks of these bridges with lighter ones, live load carrying capacities can be improved cost effectively. Hence, the New York State used Fiber reinforced polymer (FRP) composite systems, in few such cases, to remove allowable live load restrictions. Recently, a lighter FRP deck was used to replace a concrete bridge deck of an old truss bridge, on an experimental basis. Load tests were conducted to evaluate the deck behavior at serviceability limit state level. Validated finite element models were then developed to predict the failure modes of this bridge when subjected to overload and thermal effects. This paper will summarize that study.
