In this paper the thermo-mechanical behaviou r of RC bridge decks strengthened with externally bonded FRP laminates is investigated by considering environmental conditions responsible of thermal states different from the normal ones. A parametric analysis is performed by varying the slab thickness, the FRP reinforcing percentage, the type of fibre and the thickness of the protection layer. The resu lts are given in terms of ultimate bearing capacity of the slabs, which allows individua ting the conditions responsible of premature FRP-to-concrete debonding or temperature levels greater than the glass transition temperature of the adhesive.

Abstract
In this paper the thermo-mechanical behaviou r of RC bridge decks strengthened with externally bonded FRP laminates is investigated by considering environmental conditions responsible of thermal states different from the normal ones. A parametric analysis is performed by varying the slab thickness, the FRP reinforcing percentage, the type of fibre and the thickness of the protection layer. The resu lts are given in terms of ultimate bearing capacity of the slabs, which allows individua ting the conditions responsible of premature FRP-to-concrete debonding or temperature levels greater than the glass transition temperature of the adhesive.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
