“…Recent research about the topic, reinforcement and reparation of structural wood elements, preferably studies beams of solid and laminated wood, that potentially or in-service structures exist for future edifications. For example, Jasiénko y Nowak (2014) reinforced beams with new and old wood with the purpose of evaluating different configurations of epoxy adhesive and flexion tested steel plaques; likewise, Frankeet al (2015) reported different reinforcement techniques for beams depending on the kind or origin of the failure.…”

Wooden structure restorationwork in historical buildings requires substitution and/or reparation of structural elements. The aim of this investigation is to compare the density, wave velocity, dynamic module, and quality factor intest pieces of solid wood, laminated wood and a multimaterial of P. pseudostrobus. The work hypothesis proposes that dynamic modules of laminated wood and multimaterial laminated wood reinforced with stainless steel mesh are, at least, equal to solid wood. Small dimension test pieces made of solid wood, laminated wood, and multimaterial wood elaborated with the species P. pseudostrobus were prepared. Humidity content and apparent density of wood were determined. Ultrasound tests in radial, tangential, and longitudinal direction were doneand wave velocity, dynamic module, and quality factor were determined. Empiric evidence indicates that wave velocity, dynamic module, and quality factors are different with the three kinds of test pieces. Laminated wood and multimaterial wood characteristics are similar to P. pseudostrobus solid wood; so that the two compound material have good expectations to substitute some pieces that work as resistance elements in wooden structures.

“…Over the last twenty years, many studies have been performed with regard to the flexural rigidity and load-bearing capacity of hybrid beams; not only experimentally [5][6][7][8], but also analytically [9][10][11][12][13][14] and numerically [15][16][17][18][19]. In most of the mentioned studies much larger cross sections than those used for windows were investigated (e.g., up to 500 mm in height) [12,15].…”

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.
