“…Fiber-reinforced polymers can outperform concrete and steel because of their dimensional stability, high strength and light weight properties. Case studies show the average FRP bridge is half the weight of a steel bridge with the same strength and is five times lighter than its concrete equivalent [22][23][24]. Additional benefits of a lighter structure are reductions in energy and construction costs (i.e., transportation, erection, supporting foundations, construction time).…”

“…Depending on the properties of the resins and fibers used within FRP structures, they can be fire and ultra-violet (UV) resistant, electromagnetically transparent, impact resistant, have low thermal conductivity, provide no electrical conductivity, and have low maintenance costs [15,16,23]. They are highly durable, have a life span up to 100 years, and require little to no maintenance for their entire life cycle; allowing FRP structures to pay for themselves over time [24][25][26][27][28].…”

The Use of Fiber-Reinforced Polymers in Wildlife Crossing Infrastructure

et al. 2020

The proven effectiveness of highway crossing infrastructure to mitigate wildlife-vehicle collisions with large animals has made it a preferred method for increasing motorist and animal safety along road networks around the world. The crossing structures also provide safe passage for small-and medium-sized wildlife. Current methods to build these structures use concrete and steel, which often result in high costs due to the long duration of construction and the heavy machinery required to assemble the materials. Recently, engineers and architects are finding new applications of fiber-reinforced polymer (FRP) composites, due to their high strength-to-weight ratio and low life-cycle costs. This material is better suited to withstand environmental elements and the static and dynamic loads required of wildlife infrastructure. Although carbon and glass fibers along with new synthetic resins are most commonly used, current research suggests an increasing incorporation and use of bio-based and recycled materials. Since FRP bridges are corrosion resistant and hold their structural properties over time, owners of the bridge can benefit by reducing costly and time-consuming maintenance over its lifetime. Adapting FRP bridges for use as wildlife crossing structures can contribute to the long-term goals of improving motorist and passenger safety, conserving wildlife and increasing cost efficiency, while at the same time reducing plastics in landfills.Sustainability 2020, 12, 1557 2 of 15 connectivity for particular species [8]. Although usually more expensive than underpasses [3], overpasses are also frequently chosen by some species [9].The length and the width of overpasses continue to challenge engineers, architects and ecologists. Some overpasses are required to span six or more lanes, including Canada Highway 1 in Yoho National Park and Interstate Highway 90 in the Cascade Mountains of Washington. Some newer designs are anticipated to exceed lengths spanning 10-12 lanes. The proposed wildlife overpass on Highway 101 in Liberty Canyon, California, will require bridge spans up to 60 meters (m) and be the largest wildlife overpass ever built, as seen in Figure 1 [10]. Common widths of overpasses have been designed from 30 to 60 m and even wider. These geometry requirements can result in massive and relatively uneconomical structures. Many existing wildlife overpass structures are constructed to support heavy loads that incorporate excessive backfill to host native habitats, such as forests. This design feature adds substantial weight to the static and environmental loads the structure is required to support. Supporting these loads over multi-lane roadways further results in relatively high costs compared to underpasses or other less-effective mitigation measures. Because of the costs, the siting of these structures is especially challenging as they can only be provided sparingly across a large area where WVCs commonly create safety issues for drivers.

“…The advantages of composites, such as: relatively high strength and stiffness, low volume weight, good fatigue resistance, high material damping, and good environmental resistance make them attractive for different applications, including bridge and in particular footbridge industry and design (refer to references [1][2][3][4][5][6][7][8][9][10]). Therefore, the adoption of this relatively new material in this branch of engineering has already been started and developed.…”

Short and Long Term Measurements in Assessment of FRP Composite Footbridge Behavior

2020

The paper presents application of different sensors for the purpose of short and long term measurements, as well as a structural health monitoring (SHM) system to assess the behavior of a novel fiber reinforced plastics (FRP) composite footbridge. The aim is to present a thorough and concise description of these sensors networks and results gathered with their aid during in situ measurement of strains, displacements, and vibrations, as only a few works are available in this field. The bridge geometry, material solutions, and properties are described at first. Then the measurement devices composing the system and subsystems of sensors are elaborated on. Subsequently, the bridge research program is described and the results are shown and discussed. Finally, it is concluded that the use of selected sensors is helpful in assessment of the behavior of the novel structure, and moreover in validation of its numerical models. The collected data confirmed many assumptions made during the bridge design process and allowed us to accept it for exploitation.

“…Nonetheless, available studies confirm that FRP structures could achieve relevant sustainability goals; a significant example is the Aberfeldy footbridge, whose structural performance has not significantly declined 20 years after construction [5]. Sustainable construction with FRP is possible especially thanks to the immunity to electrochemical corrosion [6], meaning also superior performances in chlorine-affected environment if compared to steel [7]. Current research concerns the impact of loads and environmental factors on FRP structures' and retrofits' durability [8].…”

Fibre-reinforced polymer (FRP) profiles, with their low density, high durability, and ease of construction, are particularly suitable for the retrofit of traditional masonry structures, particularly historic constructions in seismic zones. However, a critical aspect of this new technology application is the connection between FRP profiles and masonry walls. So far, no research studies are available on this subject. The authors carried out a preliminary experimental campaign on different connection systems between masonry and pultruded glass-fibre-reinforced polymer (GFRP) profiles. The note presents the immediate results of this study, focusing on the performance and collapse mechanisms; the study may contribute to the development of an effective connection system between masonry and FRP profiles to be adopted in the retrofitting of existing building with juxtaposed FRP frames.
