Static and Fatigue Behaviors of Precast FRP-Concrete Composite Deck for Cable-Stayed Bridge

The precast FRP-concrete composite deck enables a reduction of the weight by 50% compared to reinforced concrete decks owing to the composition of a FRP panel with concrete. Therefore, the application of such deck in cable-stayed bridge will reduce effectively the weight of the superstructure leading also to substantial savings of the materials required for the superstructure and substructure and, subsequently, to achieve significant improvement of the economic efficiency. In view of these advantages, a precast FRP-concrete composite deck is selected and newly designed as a deck economically applicable to cable-stayed bridge. The applicability of the deck system is verified through static and fatigue tests.
