“…11 Most connections reported were tested with one bolt. 12–33 A few experimental results with multi-bolt connections can also be found. 34–40 Specimens were mostly loaded in double-lap configuration while few were loaded in single-lap configuration.…”

“…40 recommend the minimum ratio of g/d = 3 and s/d = 2.5. In addition to these geometrical parameters, reported studies also provide information on the influence of pultruded material orientation, 13,19,20,23,37 the type of fastener, 14 washer size, 12 hole clearance, 16,27 number of bolts and their arrangement, 34,37 environmental effect, 18,21,22, 24–26,31,39 and degree of orthotropy. 12,34 Abd-El-Naby and Hollaway 12,34 show that the failure mode is related to the proportion of CSM and CSR in the plate.…”

30This paper presents the effect of geometric parameters on the behavior of bolted GFRP 31 pultruded plates for civil engineering applications. After a literature review, results of an 32 experimental analysis investigating the behavior of GFRP-to-steel single-lap bolted 33 connections are presented. Then, a finite element analysis validated by experimental data is 34 used to evaluate the effects of the end-distance, side-distance, gage, pitch and plate 35 properties on the strength and failure mode of the connection. A critical examination of 36 geometric recommendations proposed in design references is presented. Bearing failure 37 caused by contact of the bolt on the GFRP plate is usually defined as the preferred failure 38 mode. With highly orthotropic plate, this type of failure was found to be less likely to occur 39 when loading is applied in the pultruded direction. The investigation showed that the 40 minimum end-distance and pitch-distance recommended by design references usually 41 produce a connection with the maximum capacity. However, it was found that the 42 minimum side-distance recommended by these references does not necessarily lead to the 43 maximum capacity for one-bolt and for two-bolt in a column connections. 44

“…Durability of externally bonded FRP composites in concrete structures is reviewed in a recent paper [70]. There is a lack of long-term durability and performance data for FRP profiles and their joints [71]. Durability of FRP composites exposed to elevated temperature and fire, ultraviolet radiation, creep and fatigue loads, freeze-thaw conditions and moist environment is discussed in a comprehensive book by Karbhari [72].…”

Construction produces a third of global carbon emissions. These emissions cause global warming and contribute to climate emergency. There is a need to encourage use of sustainable and eco-friendly materials to effectively deal with climate emergency. Fibre-reinforced polymer (FRP) is an eco-friendly material with low-carbon footprint. FRP composites in civil engineering are mainly used in three applications: (1) FRP profiles in new-build; (2) FRP-reinforcing bar in concrete members and (3) FRP in repair and rehabilitation of existing structures. This chapter presents basic properties of constituent materials (fibres and polymer resins), mechanical properties of FRP bars, strengthening systems and profiles, manufacturing processes and civil engineering applications of FRP composites. Durability, sustainability and recycling of FRP composites are also discussed.

“…The design guidelines available for response of FRP beam-to-column joints are very limited [19]. Past research is mainly concentrated on moment-rotation response of FRP beam-to-column joints subjected to monotonic loading only [12,[14][15][16][20][21][22][23][24][25][26][27]. The research on cyclic performance of FRP beam-column joints is scarce; only few papers exist [7,[28][29][30][31][32][33][34][35][36][37][38].…”

This paper presents cyclic behaviour of bolted and hybrid–combined bolted and bonded fibre reinforced polymer (FRP) beam-to-column joints between I-shaped members using steel and FRP cleats. Five full-scale cyclic tests are carried out to study moment-rotation behaviour, cyclic response, and failure patterns. The test parameters include position of cleat (flange or combined web and flange), fastening method (bolting or hybrid–combining bolting and bonding) and cleat material (steel or FRP). First two tests had bolted and hybrid joints with steel flange and web double angles. Next two tests had the same joint detailing but with no web cleats. Last test used bolted joint only with FRP web and flange cleats. Three failure modes were observed: shear-out failure of the beam’s bolted zone, adhesive debonding with shear-out failure and delamination cracking. Cyclic performance of the joints was assessed by hysteresis moment-rotation curves and accumulated dissipated energy. Hybrid joints showed the best overall cyclic performance with accumulated dissipated energy about 75% higher than the bolted joints. Bolted joints with FRP cleats exhibited the worst cyclic performance. Flange cleated joints showed similar performance to web and flange cleated joints.
