According to Jiang (2007), the largest distribution of bamboo forest is found in the Asian-Pacific region, followed by the Americas and Africa. In Asia, with the exception of China, Korea, Iran, Israel and Japan, all the other Asian countries mainly use round bamboo structures. Modern architecture theories and construction technologies have been applied to traditional bamboo architecture in Thailand, Indonesia and Vietnam, where lots of large-scale modern round bamboo structures were built. China is the largest exporter of engineered bamboo products in the world (INBAR, 2018). Engineered bamboo materials are mainly used as indoor and outdoor decorative materials in large and medium-size public buildings, as well as decking materials in outdoor landscape. However, engineered bamboo materials used as structural components are basically in the demonstration stage, such as small transportation facilities or one to three-storey houses.
Production of Engineered Bamboo
Published in Yan Xiao, Engineered Bamboo Structures, 2022
As discussed in the previous chapter, engineered bamboo can have a broad definition: bamboo products that are designed, manufactured, and constructed using modern engineering concepts, procedures, including inspection, etc. Even many round bamboo culm structures are designed and built with modern engineering methodology and therefore can be considered as engineered (round culm) bamboo structures. This book, however, mainly focuses on the introduction and discussion of laminated bamboo, and specifically, glued laminated bamboo or glubam. Therefore, this chapter first discusses the manufacture of engineered bamboo.

Since the shape of raw bamboo is not entirely suitable for modern product processing, engineered bamboo materials have been developed for flexible applications in various fields. Recently, the manufacturing process for most engineered bamboo products references the techniques used for engineered wood. The main processing steps of engineered bamboo are splitting, gluing, pressing, heating, etc., which can produce different bamboo products, such as glued laminated bamboo (glubam) (Tang, Shan, Li, Peng, & Xiao, 2019) bamboo scrimber (BSC) (Kumar et al., 2016), and laminated bamboo lumber (LBL) (Wang et al., 2021). A growing number of studies have confirmed that engineered bamboo can be used as a substitute for wood. The development of engineered bamboo has produced a material comparable to wood for construction in terms of mechanical (Sharma & van der Vegte, 2020) and thermal properties. Verma, Sharma, Chariar, Maheshwari, and Hada (2014) found that the average strength of bamboo laminae was higher than that of softwood laminae and comparable to that of hardwood laminae. Therefore, the development and marketing of a variety of panel profiles such as walls and flooring made from engineered bamboo can compete with wood in some areas (Huang, 2019). Among them, LBL is a promising alternative to traditional construction materials due to its environmental compatibility and competitive physical and mechanical characteristics (Dauletbek et al., 2022).

Determination of the structural properties of bamboo is a relatively recent endeavor, for which reason literature is scarce. An extensive analysis can be found in [6, 7]. The behavior of bamboo as a structural material, with its inherently variable biological nature, has been studied under flexural and compression destructive tests, especially for strength grading purposes [8–13]. Keogh and collaborators recently studied the fatigue behavior of bamboo culms along different directions of the culm [14]. Some papers describe engineered bamboo composite materials for structural applications in construction and industry [15]. Few address the tensile behavior of full bamboo along the grain direction [10, 16]. As stated by Taylor [17], its tensile strength is unknown, since the sample will eventually fail by longitudinal splitting, making it impossible to get it to break across the culm in a controlled way. Yet the tensile strength may be as much as 100 MPa, 10 times higher than that perpendicular to the culm. Recent work has also explored the dynamic elastic properties of bamboo by means of vibro-acoustic techniques [11, 18]. Thus, the average dynamic modulus of elasticity of can be obtained in a nondestructive way.
