Sustained Load Effect on GFRP Bar Reinforced Concrete Deck


Article Preview

This paper presents the investigation of sustained stress level in GFRP bar used as main reinforcement in typical reinforced concrete bridge deck, which is often subject to severe environmental exposures in North America. AASHTO LFRD approach is used for the design of GFRP RC deck that also meets with the requirements per as specified in ACI 440.1R-06. Research results show that the sustained stress level in GFRP bar varies in the range of approx. 3% -7% for bridge deck with various deck thickness and girder spacing.
