An Investigation of GFRP Bar Reinforced Light Weight Concrete (LWC) Bridge Deck

摘要：

　　To avoid the creep rupture of GFRP bar in RC members,not exceeding 20% design tensile strength (ffu)) is recommended as design limit for sustained stress level in GFRP bar in current ACI 440.1R-06 guideline.In this paper,the effects of using light weight concrete (LWC) is studied to investigate the sustained stress level in GFRP bar RC bridge decks by a parametric study.Results show that the sustained stress in GFRP bar in LWC bridge decks is in between 2.8-5.7% of ffu,while it is about 3.44-7.52% for normal weight concrete (NWC) deck.
