“…Bridge decking is one of the more auspicious applications for FRP in infrastructure due to the benefits described above (Bakis et al, 2002;Hota & Hota, 2002;Kumar et al, 2004;Sonnenschein et al, 2016). In the UK, the first major composite footbridge was the Aberfeldy Footbridge in Scotland, which was installed in 1992 (Skinner, 2009).…”

A fibre-reinforced polymer (FRP) cycle footbridge has been proposed for construction in Bristol, United Kingdom for South Gloucestershire Council. The superstructure will span 54m, comprising a bowstring carbon fibre-reinforced polymer (CFRP) arch with a 5m wide glass fibre-reinforced polymer (GFRP) deck supported by stainless steel hangers. Recently, a methodology has been proposed that provides a structured process to assess the value of a structural health monitoring (SHM) system for a bridge prior to deployment. This methodology outputs a simple metric that quantifies the likeliness of an SHM system to yield value to an asset owner. This FRP bridge is used as a case-study to 'road test' this process. Two possible systems were considered: a system of accelerometers and a system of strain gauges. From the resulting discussions, a deployment of accelerometers received a value-rating (VR) of 4.2. A strain gauge deployment received 3.7. The scores will contribute to a monitoring specification for the FRP bridge which is currently in the design phase. Expansions to the methodology have also been proposed to better capture the potential value of an SHM system which would be of interest to structural engineers and researchers, in particular to inform model validation and research activities.

“…Fibre reinforced polymer (FRP) bridge decks have been recognised as a competitive alternative to traditional decking solutions for the refurbishment of existing bridges, as well as the construction of new ones [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. FRP decks are characterised as light, strong, corrosion-resistant decks.…”

Composite structures, vol. 117 pp. 83-97. http://dx. ABSTRACTIn the past two decades, the use of fibre reinforced polymer (FRP) decks has attracted a great deal of attention when it comes to the refurbishment of existing bridges and the construction of new ones. FRP materials offer superior properties, such as high specific strength and stiffness, light weight, high fatigue and corrosion resistance and good durability. Because of their low self-weight and prefabrication potential, FRP composites lend themselves to accelerated bridge construction, thereby leading to minimised traffic interference. However, one challenge that is posed by FRP deck systems is the detailing and design of panel level connections. Today, a common practice for joining deck panels on site is adhesive bonding, which compromises the benefit of rapid FRP deck installation due to the time-restricted curing required for structural adhesives. As a result, there is a need for the development of joints which enable more rapid assembly. In this paper, a novel joint configuration for panel level connections is proposed. Numerical analyses and static experimental tests were conducted to evaluate the behaviour and load-carrying capacity of the connection. The overall investigation showed that the presented joint concept is a potential alternative for panel level connections in FRP decks.

Substantial progress has been made in the past 25 years in the area of fiber reinforced polymer (FRP) composites as viable structural materials in bridge construction. The technologies developed to date have moved rapidly from their initial stage of concept validation, into full‐scale prototype construction and field implementations. They have been used either on their own in bridge applications or being combined with other conventional structural materials such as concrete, to provide economical solutions to many critical bridge problems such as deficiency. This paper presents a state‐of‐the‐art review of these developments on typical bridge components (i.e. decks and girders) as well as bridge systems that have been available from the early 1980s to the beginning of 2006.
