“…Several experimental programs have investigated the performance of Reinforced Timber (RT) beams with CFRP, and have shown the effectiveness of using externally-bonded CFRP materials to improve the flexural capacity of RT members [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. However, most of the previous studies were carried out using CFRP laminates externally attached to the soffit of solid wood beams along the full span length.…”

“…Yang and Liu (2007), Yang et al (2008), Shao and Liu (2007), and Shao et al (2012) conducted experimental studies on the behavior of glulam beams and columns and compared the results of regular beams and FRPreinforced beams; the test results showed that the reinforcement improved the stiffness, the load bearing capacity, and especially the ductility. Li et al (2013) conducted experiments on FRP columns to investigate the effects of different wrapping methods.…”

Nine cyclic tests were conducted on full-scale one-story, one-bay timber post and beam construction specimens to study the lateral resistance of reinforced glued-laminated timber post and beam structures. Two reinforcement methods, wrapping fiber-reinforced polymer (FRP) and implanting self-tapping screws, and two structural systems, simple frame and knee-braced frame, were considered in the experimental tests. Based on the observed experimental phenomena and the test results, the feasibility of the reinforcement was discussed; the contributions of different methods were evaluated; and the seismic performance of the specimens were studied. The results indicated that both reinforcement methods could limit the crack development and improve the strength, stiffness and energy dissipation capacity. The results also showed that the lateral resistance could be significantly improved by retrofitting a failed simple frame with joint reinforcement and a knee-brace, demonstrating that this approach can be applied in engineering practice.

“…The longitudinal modulus of elasticity of the CFRP profiles, aluminium, and GFRP profiles compared to that of Norway spruce are higher by a factor of 10.0, 5.8, and 3.2, respectively (Table 1). Thus, CFRP profiles should provide the best improvements in bending stiffness and load-bearing capacity [10,14,25]. Despite this, we decided to perform the first phase of the tests with aluminium reinforcements only, in order to define their positioning and orientation effect on the observed parameters and to analyse the possibilities of manufacturing window profiles with non-visible reinforcements.…”

“…To improve bending stiffness, load-bearing capacity and flexural-rigidity the reinforcements need to be positioned near tensile and compressive faces, as far away from the neutral axis as possible [9,15,25,29]. The position and orientation of the reinforcements in the specimens, B, C, and D, were defined, taking into account number of different aspects:…”

Modern architecture suggests the use of opened spaces with large transparent envelope surfaces. Therefore, windows of long widths and large heights are needed. In order to withstand the wind loads, such wooden windows can be reinforced with stiffer materials, such as aluminium (Al), glass-fibre reinforced polymer (GFRP), and carbon-fibre reinforced polymer (CFRP). The bending stiffness, load-bearing capacity, and flexural rigidity of hybrid beams, reinforced with aluminium, were compared through experimental analysis, using a four-point bending tests method, with those of reference wooden beams. The largest increases in bending stiffness (29%-39%), load-bearing capacity (33%-45%), and flexural rigidity (43%-50%) were observed in the case of the hybrid beams, with the highest percentage of reinforcements (12.9%-six reinforcements in their tensile and six reinforcements in their compressive zone). The results of the experiments confirmed the high potential of using hybrid beams to produce large wooden windows, for different wind zones, worldwide.
