“…FRP bridge decks are mainly made of E-glass fibers and thermosetting resins such as polyester (owing to their low cost) and vinylester (preferable material used in moist environments 6 ). This solution has proved its efficiency owing to the advantages of light weight, 18,25,[33][34][35][36][37][38][39][40][41][42][43][44][45][46] high strength, 6,18,25,34,36,40,41,[45][46][47][48][49][50][51] and improved durability. 34,36,45,46,48,49,[52][53][54][55] Moreover, the benefits of FRP decks include corrosion resistance 18,25,35,36,47,52 and, therefore, longer service life 33 while still demonstrating lower life-cycle costs.…”

Currently, the application of pultruded profiles is increasing owing to their advantages, such as light weight, high strength, improved durability, corrosion resistance, ease of transportation, speed of assembly, and nonmagnetic/nonconductive characteristics. This review analyzes the main application fields of elements produced by pultrusion manufacturing processes: bridges and bridge decks, cooling towers, building elements and complete building systems, marine construction, transportation, and energy systems. Analysis of the scientific literature in relation to the mechanical behavior of pultruded elements is presented as well. Finally, this review outlines the future study possibilities, giving the researchers and practitioners the directions for deeper investigation of specific features and exploration of new ones concerning the mentioned aspects of pultruded fiber-reinforced polymer composites.

“…Weak axis bending of the deck system significantly affects the behavior of adhesive joints. To the authors' knowledge, only a few studies on the weak-axis bending of deck systems have been reported, and these did not consider the behavior of the adhesive joints [8][9][10]. Our previous study described the failure modes in the adhesive joints of pultruded GFRP decks under weak-axis bending, including failures of adhesive and deck substrates [11].…”

Glass-fiber-reinforced polymer (GFRP) decks have been widely used in the rehabilitation and construction of bridges as a replacement for conventional deck materials, such as steel, concrete, and wood. In this study, an analysis method for checking the local safety of joints in adhesively connected GFRP decks under bidirectional bending due to traffic wheel loads is newly presented. This method can be applied for designing and evaluating the joints of other FRP decks. The orthotropic material properties of the deck were approximately assumed according to the test results and previous research. Three-dimensional solid elements were used to simulate the local behavior of the adhesive and deck substrates at the joints. Global deflections of the deck and local deformations of the adhesive were evaluated for serviceability. The local stresses in the adhesive and deck substrate are evaluated at the joint to check for local failure modes of the joint under serviceability and ultimate limit states. The analysis results indicate that local failures of the adhesive and deck substrate at the joint occurred. Recommendations for avoiding these local failures and performing more precise analysis are suggested.

“…Besides, hardly any continuous fibre for pultruded FRP is present in the transverse (perpendicular to the pultrusion) direction. Therefore, it exhibits a small bearing capacity and considerable deformation when subjected to transverse bending, and its load-displacement curve displays a strong nonlinearity in the transverse direction (Park, Kim, Lee, & Hwang, 2005;Qiao, Davalos, & Brown, 2000;Salim, Davalos, Qiao, & Kiger, 1997). The nonlinearity is strongest in rectangular sections because of low shear stiffness (BazÏant & Cedolin, 1991).…”

Hybrid bridge decks with the pultruded fibre reinforced polymer have advantageous properties but easily crack because of their unsatisfactory transverse strength and shear strength. This study proposed a type of bridge deck composed of innovative pultruded fibre reinforced polymer composite sandwich panels. Using four-point bending tests, concentric wheelloading tests and eccentric wheel-loading tests combined with first-order shear deformation theory, this study investigated the failure mode, flexural capacity, deformation and ductility of hybrid bridge decks under different working conditions. Under four-point bending and concentric wheel loading, the primary failure modes for this hybrid bridge deck were shear failures along the fibre direction and buckling failure of the upper panel. Under eccentric wheel loading, the primary failure mode was a torsional failure due to the eccentric load. The bearing capacities of the hybrid bridge deck under the three working conditions were 3.8, 3.5 and 3.2 times the service load of a Class I vehicle load, respectively. Besides, the hybrid bridge deck remained in the linear elastic stress state at 2.6 times the service load, indicating that this hybrid bridge deck withstands relatively large vehicle overload without visible damage. The ductility values of this hybrid bridge deck under the three working conditions were 1.79, 2.09 and 2.00, respectively, which are higher than the values for an ordinary pultruded bridge deck. Therefore, the proposed design has the relatively good energy-dissipating capacity, which improves the emergency capacity of the bridge deck.
