“…Biomaterials like wood, bamboo, and rattan are promising construction materials because they are sustainable and environmentally friendly (Lakkad and Patel 1981;Amada et al 1997). Compared with wood, bamboo grows faster, can be harvested in 3 to 5 years, and has a similar or higher strength-to-weight ratio than wood (Nogata and Takahashi 1995;Albermani et al 2007).…”

The mode II fracture toughness of bamboo scrimber was evaluated. A compact shear specimen was chosen as the specimen, while the stress intensity factor KIIC was chosen as the index for the mode II fracture toughness. In total, 54 specimens containing two different grain modes and three different thicknesses were manufactured and subjected to static loading with specially designed loading clamps. The failure modes were observed, and the crack initiating loads were obtained. The stress intensity factor was calculated and analyzed. The failure of all specimens was due to brittleness and occurred instantaneously. Thus, the linear elastic fracture mechanics is applicable to the mode II fracture of bamboo scrimber. The stress intensity factor KIIC was 459.9 MPa·m 1/2 for the F-L grain mode and 358.0 MPa·m 1/2 for the S-L grain mode. There was no significant difference in the stress intensity factor KIIC of specimens where the thickness ranged from 10 mm to 30 mm; a specimen with a thickness of 10 mm can be used to determine the fracture toughness of the bamboo scrimber.

“…Wood and bamboo are attractive engineering materials due to their renewability, easy accessibility, low energy consumption and pollution, and their high strength-to-mass ratio (Liese 1987;Simpson and TenWolde 1999;Jiang and Peng 2007;Fakoor and Rafiee 2013). As an abundant natural resource in Asia, bamboo has been used as a non-structural and structural material in many areas (Chung and Yu 2002;Albermani et al 2007;Xiao et al 2009;Deng et al 2014a): as bamboo-based, compositecovered bamboo particleboard (Zhang et al 1997), bamboo fiberboard (Matsumoto et al 2001), bamboo strandboard (Sumardi et al 2006), and bamboo-bundle laminated veneer lumber (Deng et al 2014b,c;Chen et al 2014).…”

“…Taylor et al (2015) focused on the role of bamboo nodes relative to culm stiffness and strength, and the experimental results indicated that the node could be explained as an attempt to reinforce a biologically essential feature, which would otherwise be a point of weakness when loaded in tension and bending. The mechanical properties and connecting joints of bamboo culm are suitable for a lightweight bamboo double layer grid system for construction applications (Albermani et al 2007). An investigation of the effect of uniaxial and biaxial compression loadings on the circumferential-radial mechanical properties has shown that the diametric strength of bamboo evaluated by biaxial load was 2.4 to 2.5 times the uniaxial compression (Jiang et al 2012).…”

As an abundant natural resource in Asia, bamboo is receiving increased attention as an engineering material due to its renewability and excellent strength. The parallel-to-grain compression and shearing properties of moso bamboo culm were examined. The growth characteristics (bamboo age, nodes, and location along the culm), as well as treatments for practical applications (hole punching and hoop reinforcing by hose clamp) were investigated for their influence. Mechanical tests were conducted in accordance with the ISO22157 T 15780-1995 (1996) standards. Acceptable loading rates for the parallel-to-grain compression and shearing tests were 0.1 and 0.05 mm/s, respectively. The compressive and shearing strengths increased from the bottom to the top of the bamboo. Bamboo age and nodes exerted little influence on parallel-to-grain compressive and shearing strength. In addition, hole punches diminished the mechanical strength of the bamboo culm, while hose clamps enhanced it slightly.
