A review of mechanical behavior of structural laminated bamboo lumber

Abstract

The transition of the construction sector to sustainable development mostly depends on the environmental friendliness of building materials. This, in turn, calls for the development of new, strong, and sustainable materials that would be a worthy alternative for traditional materials, including wood. Over the past decade, laminated bamboo lumber (LBL) has received much attention from engineers, practitioners, and scientists for its attractive mechanical properties, comparable to and in some cases superior to hard and softwood. Moreover, the sustainability of LBL is characterized by its high carbon sequestration, fast time to harvest, high yield, and low energy consumption for processing. However, the behavior of LBL is not yet fully understood, which in turn affects the low awareness and application of the material by practitioners and engineers around the world. Since LBL has a promising future, this article will contribute to a better understanding of its mechanical properties and a more accurate design, taking into account the influencing factors. This article discusses the mechanical properties of three types of structural LBL, namely beams, columns, and sheathing panels. The previous works of researchers on the mechanical properties of structural LBL were reviewed, and thus the most common failure modes, the causes of the destruction of structural elements, and the factors that affect their behavior were discussed and described. This work will serve as a reference for current practitioners and future research.

A Review on Flexural Properties of Wood-Plastic Composites

“…To reduce the carbon footprint of the built environment [ 5 ], waste wood and recycled plastics can be used as raw materials to produce environmentally friendly WPC, which can meet the performance requirements of construction [ 6 , 7 , 8 ]. Green transformation of the construction industry depends on the environmental friendliness of building materials [ 9 ].…”

Manufacturing and Characterization of Wide-Bundle Bamboo Scrimber: A Comparison with Other Engineered Bamboo Composites

“…LBL is made by stacking and gluing uniformly milled bamboo elements, producing a uniform element shape, size, and orientation in the product. The average strength of structural LBL is similar to flattened bamboo and hardwoods [ 62 ]. Several studies have demonstrated the unique properties of structural LBL [ 62 , 63 , 64 , 65 , 66 ].…”

“…The average strength of structural LBL is similar to flattened bamboo and hardwoods [ 62 ]. Several studies have demonstrated the unique properties of structural LBL [ 62 , 63 , 64 , 65 , 66 ]. Structural members made of LBL can be created in any cross-section and shape and are adaptable to different heights and spans of members.…”

Design and manufacture of laminated veneer lumber packaging boxes and pallets and evaluation of their mechanical properties

“…They have been replaced by artificial boards such as oriented strand board (OSB) and laminated veneer lumber (LVL). This effectively alleviates the waste of high-quality wood and makes full use of the excellent mechanical properties of wood-based panels (Cui 2014;Dauletbek et al 2021;Su et al 2021;Yang et al 2021).…”
