The present work describes experimental tests performed on full scale concrete members reinforced with FRP rebars subjected to localized increase of temperature. The specimen are reinforced with GFRP rebars made of unidirectional E-glass fibres. Sand coated GFRP rebars with a diameter of 16 mm and a spiral wound, to increase bond to concrete, were adopted for the bottom reinforcement. The aim of the research was to verify the residual mechanical properties of this kind of structural elements reinforced with GFRP rebars after an increase of temperature similar to localized fires.

Abstract
The present work describes experimental tests performed on full scale concrete members reinforced with FRP rebars subjected to localized increase of temperature. The specimen are reinforced with GFRP rebars made of unidirectional E-glass fibres. Sand coated GFRP rebars with a diameter of 16 mm and a spiral wound, to increase bond to concrete, were adopted for the bottom reinforcement. The aim of the research was to verify the residual mechanical properties of this kind of structural elements reinforced with GFRP rebars after an increase of temperature similar to localized fires.File in questo prodotto:
