The Effect of GFRP Wrapping on Lateral Performance of Double Shear Lap Joints in Cross-Laminated Timber as a Part of Timber Bridges

open access: yesBuildings, 2022
Timber elements, such as timber bridges, are exposed to heavy loads. Therefore, reinforcement might be useful. Due to a lack of wood supplies, poplar, a fast-growing tree, could be used to construct CLT (cross-laminated timber).

Comparative Analysis of Mechanical Properties for Wood Frame and Reinforced Concrete Frame Based on Deformation Energy Decomposition Method

open access: yesBioResources, 2023
As a typical orthotropic material, the mechanical properties of wood in the parallel and perpendicular-to-grain directions are very different. Based on mathematical orthogonality, mechanical force balance condition, and energy comparability, the ...

Quantitative Anatomical Characteristics of Compression Wood, Lateral Wood, and Opposite Wood in the Stem Wood of Ginkgo biloba L.

open access: yesBioResources, 2018
Quantitative aspects were investigated and compared for anatomical characteristics among compression wood (CW), lateral wood (LW), and opposite wood (OW) in the stem wood of Ginkgo biloba. Characteristics of each part were observed in the 5th, 10th, and 15th to 20th growth rings via optical and scanning electron microscopy.

Microfibril Angles and Crystalline Properties of Reaction Woods in Agathis and Sumatran Pine Woods

open access: yesJurnal Sylva Lestari, 2023
The microfibril angles (MFAs), relative crystallinity index (RC), and crystallite width (CrW) of compression wood (CPW), lateral wood (LTW), and opposite wood (OPW) in Agathis (Agathis loranthifolia) and Sumatran Pine (Pinus merkusii) stem wood were ...

Lateral Stability of Wood Beam-and-Deck Systems [PDF]

open access: yesJournal of the Structural Division, 1973
Modern timber structures frequently employ large wood beams bridged by 2 in. wood decking. Economy of material dictates the use of deep narrow beams whose design is limited by considerations of lateral instability. Such constructions must rely upon the in-plane shear rigidity of the attached deck to prevent collapse, yet when decks of low rigidity such

Lateral Performance for Wood-Frame Shear Walls–A Critical Review

open access: yesJournal of Renewable Materials, 2023
Wood is a green material in line with the sustainable development strategy. From the excellent performance of engineering wood products, modern wood structures represented by light wood structures have gained more development opportunities. As an indispensable part of light wood structure systems, the wood-frame shear wall plays a vital role in the ...

Space-time Analysis of the Longitudinal Variation in Wood Specific Gravity of Teak and Its Effect on Tree Growth and Development

open access: yesBioResources, 2023
The space-time structure of a teak wood specific gravity (SG) dataset was analyzed using a mixed-effects model. Spatial correlation increased in space, a phenomenon attributable to the maturation of apical meristems, while the temporal correlation of ...
