“…The bamboo oriented strand board process represents one of the best opportunities for automation, property control and consistency, mass production, and resin efficiency in manufacture of bamboo-based building materials, with minimal waste. It is an excellent industrial material as a substitute for wood structural board [9,10]. The applications of bamboo strand board in building structures, such as bamboo I-beam, can broaden the utilization scope of bamboo.…”

Novel bamboo I-beams fabricated from bamboo oriented strand boards as structural members were investigated. Bending tests were performed to determine the stiffness and strength properties of bamboo I-beams. The results showed that the stiffness and strength properties exceeded the requirements of APA EWS Performance-Rated I-joist in PRI-400-2012. Increasing section depth had obvious effect on the ultimate load capacity, stiffness and failure mode of bamboo I-beams. Moreover, the bending properties of bamboo I-beams were also affected by flange materials, joint type in web, and reinforcement of flange finger joints. The strain measurements indicated that the plane assumption could be applied to the bamboo I-beams. Based on the stiffness calculation formula of I-beams recommended in Canadian standard and the moment capacity calculation formula corresponding to each failure mode of I-beams, the calculated stiffness and ultimate load capacity of specimens were relatively close to the experimental results.

“…Several parameters were considered including wood species and their combination; strand dimensions, orientation, compaction and density profile; void content; fines content; as well as resin type, content, and distribution. The methodology has recently been applied to bamboo OSBs (Dixon et al, 2017) to predict their flexural MOE by accounting for the different microstructures of wood and bamboo.…”

The strain-softening response and failure of oriented strand boards (OSB) are investigated both experimentally and numerically. Standard tests are used to characterize the elastic (MOE) as well as damage properties (damage height, damage initiation strain and fracture energy) of OSB in two principal (parallel and perpendicular) directions. Experimental data are then used in conjunction with a recently developed physically-based damage model to simulate the nonlinear response of notched OSB samples under tension using the finite element (FE) method. Acceptable agreement between the FE simulations and experimental data are found. The results suggest that a strain-softening approach is capable of accurately modelling the damage progression in notched OSB samples.

“…Research has shown that eucalyptus can replace pine wood, but Red cedar describes mechanical performance. Dixon et al 2017 [6] found a model for meso bamboo OSB board from the point of modulus of elasticity, on major and minor axis. All the determinations were made in accordance with EN 300: 2006, and the boards made from high density species showed better physical performances, while the boards made from low density wood species had high mechanical properties.…”

The paper aims to discover the characteristics of softwood species used in the technology of oriented strand board. In this sense, the main physical-mechanical properties of three wood species (fir, spruce, and pine) were determined and obtained, based on the European standards. The physical properties of the solid wood will be compared with the characteristics of the oriented strand boards obtained from each resinous wood species, in a future work. From the analysis of wood properties, it was found that the softwood species are the best corresponding specie to this technology, because they have soft and light wood (due to their low density), and their higher mechanical strength will give very good mechanical strength of the boards. As a final conclusion of this work, it can be stated that the softwood species remain the basic species of the technology for the manufacture of oriented wood strand boards, due to their low density (thus good compressibility and compactness) and superior mechanical properties.
