“…Researchers have attempted various applications of FRP in bridge deck systems. Three major types of bridge decks using FRP composites are concrete bridge decks reinforced with FRP bars or FRP grids (Bank et al 2006, El-Ragaby et al 2007a, all FRP composite bridge decks (Bakis et al 2002, Kumar et al 2004, Wan et al 2005, Keller and Gürtle 2005, Jeong et al 2007, Liu et al 2008) and hybrid FRP-concrete bridge decks (Hillman and Murray 1990, Bakeri and Sunder 1990, Van Erp et al 2005, Keller et al 2007, Schaumann et al 2008.…”

“…Van Erp et al (2005), Kitane et al (2004), and Alnahhal et al (2008b) proposed a similar type of hybrid FRP-concrete decks consisting of FRP hollow profiles in the tension zone and a layer of concrete in the compression zone. Another type of hybrid bridge deck was investigated by Keller et al (2007), Schaumann et al (2008) and Hanus et al (2008), consisting of FRP sheet with T-upstands or grids as SIP forms and concrete cast on them. Chen et al (2009) proposed a hybrid FRP-concrete bridge deck system consisting of U-shaped FRP beams and reinforced concrete slab in the compression zone.…”

This paper presents a new cost-effective hybrid GFRP-Concrete deck system that the GFRP panel serves as both tensile reinforcement and stay-in-place form. In order to understand the fatigue behavior of such hybrid deck, fatigue test on a full-scale specimen under sagging moment was conducted, and a series of static tests were also carried out after certain repeated loading cycles. The fatigue test results indicated that such hybrid deck has a good fatigue performance even after 3.1 million repeated loading cycles. A three-dimensional finite element model of the hybrid deck was established based on experimental work. The results from finite element analyses are in good agreement with those from the tests. In addition, flexural fatigue analysis considering the reduction in flexural stiffness and modulus under cyclic loading was carried out. The predicted flexural strength agreed well with the analytical strength from finite element simulation, and the calculated fatigue failure cycle was consistent with the result based on related S-N curve and finite element analyses. However, the flexural fatigue analytical results tended to be conservative compared to the tested results in safety side. The presented overall investigation may provide reference for the design and construction of such hybrid deck system.
