초록

Fatigue Behavior of a GFRP bridge deck consisting of rectangular unit modules is studied by an experimental method. The experiment focuses on how the damage in the transverse direction influence the overall behavior of the deck It is proposed filling the space in each module with a soft foam. Using the recent experimental data, the fatigue behavior is discussed. If the space of the deck is filled with the foam, the fatigue life of the deck was increased about 1,000 times for the same level of the stress variation as the reference deck not filled.
