“…The increasing demand for carbon reduction (D'Amico et al, 2021;Hart et al, 2021) and the advantages of engineered wood products have driven studies to enhance their structural capacity (Franzoni et al, 2016(Franzoni et al, , 2017(Franzoni et al, , 2018Peixoto et al, 2021). The integration of engineered wood products with other materials is being explored as a strategy for decarbonizing new buildings (D'Amico et al, 2021).…”

“…The integration of engineered wood products with other materials is being explored as a strategy for decarbonizing new buildings (D'Amico et al, 2021). This can be achieved by combining wood with materials such as concrete (Sebastian et al, 2017), aluminum (Chybiński & Polus, 2019), bamboo (Sun et al, 2020), and steel (Chiniforush et al, 2018;Hassanieh et al, 2016aHassanieh et al, , 2016bHassanieh et al, , 2017Peixoto et al, 2021;Soriano et al, 2016). Soriano et al (2016) increased the overall mechanical capacity of GLULAM by incorporating 10 mm diameter steel bars through grooves fabricated symmetrically along the neutral axis and the entire length of the GLULAM.…”

“…To the best of author's knowledge, the literature has yet to investigate the topological optimization of timber structures with reinforcement such as steel rods (Mayencourt & Mueller, 2019Peixoto et al, 2021;Soriano et al, 2016). In this sense, this work aims to develop a methodology based on the BESO method to find the best positioning of reinforcement for GLULAM structures subjected to static loads and volume constraints.…”

Glued-Laminated Timber (GLULAM) is a widely-used building material, popular for its strength, durability, and sustainability. It is created by bonding together layers of wood, making it a common choice for civil structures. In this study, Bi-directional Evolutionary Structural Optimization (BESO) is proposed to improve the performance of GLULAM structures. By positioning steel bars within the GLULAM structure, the objective is to increase the structure's stiffness and enhance its structural integrity. To achieve this, the study introduces the concept of a sub-design domain and utilizes optimization theory to determine the optimal placement of the steel bars. The finite element problem is solved using ANSYS software, while the topological optimization problem is solved using MATLAB software. The use of sub-design domains and optimization theory enables the optimal placement of the reinforcements to be determined. The results of this study demonstrate the potential of this approach for enhancing the structural integrity and stiffness of GLULAM structures under static loads.

“…Among the materials used for reinforcement in glulam beams, metallic and fibrous materials stand out. The first type shows high mechanical properties using steel bars and steel plates (PEIXOTO et al, 2021;WANG et al, 2021). In the second type of reinforcement materials, natural fibres of sisal and flax can be mentioned, which can be grown in abundance and with low processing costs (BORRI; CORRADI; SPERANZINI, 2013).…”

Synthetic fibres applied as reinforcement in glued laminated timber (glulam) intend to increase the mechanical performance of beams, changing the brittle to ductile mechanical behaviour of wooden beams. This paper investigates the experimental results of glulam beams reinforced with synthetic fibre subjected to bending and compares them with those obtained by both an analytical method and the numerical method using the Ansys® software. Glulam beams were produced with a low-grade strength class wood species (Pinus elliottii) glued with an adhesive of emulsion isocyanate polymeric and reinforced with Vectran® synthetic fibres, positioned on the bottom of the beam. This type of fibre is not yet widely used for structural reinforcement. A three-point bending test was performed for loading in the elastic regime of the glulam beams. The results obtained indicate acceptable approximations of vertical displacements and normal stresses due to the bending of the beam with eight layers of synthetic fabric, both favourable to structural safety, in addition to the significant increase in stiffness of glulam with the introduction of Vectran® fibre reinforcement.
