“…Another example is the buckling failure observed in compression parallel to grain tests in this and other studies [12,33,14]. The buckled shape is not an acceptable failure mode in timber specimens [24] and as discussed previously, does not represent the compressive strength of the material.…”

“…The difficulty in making connections and joints suitable for round (and variable) sections is also prohibitive for mainstream construction; however increasing research demonstrates a growing industry and demand for sustainable building products. Studies vary from the use of full culm bamboo in construction and scaffolding (e.g., [5][6][7][8][9][10] to engineered bamboo composites (e.g., [11][12][13][14][15][16][17][18][19][20][21]. Engineered bamboo composites are of particular interest due to the standardisation of shape and the relatively low variability in material properties [22].…”

Bamboo is potential as an alternative material to substitute wood. This paper examines the effects of using different resin contents and strand dimensions on the properties of its oriented strand board (bamboo OSB). Tali bamboo (Gigantochloa apus (J.A. & J.H. Schultes) Kurz) was used as raw material in manufacturing the bamboo OSB. Laboratory scale oriented bamboo strand boards were fabricated using each bamboo strand length (7.5, 10, and 15 cm) and glued with liquid phenol formaldehyde adhesive at various resin contents (6, 7 and 8%) of the bamboo strands dry 3 weight. Results show that the average density of fabricated bamboo OSB was 0.75 g/cm. Physical and mechanical properties of bamboo OSB were significantly affected by resin content, except the modulus of elasticity (MOE). Higher resin content gave better physical and mechanical properties of the boards. MOE of bamboo OSB was also significantly affected by the strand length. The longer strand dimension produces boards with higher MOE values. All oriented bamboo strand boards studied meet the Indonesian and Japanese Standard requirements of type 24 particleboard and also meet the British Standard requirements of both Type OSB/2 and Type OSB/3.

“…Additionally, the experimental results of mechanical characterization in glued laminated Guadua a.k. reveals higher strength and comparable stiffness compared to those of engineered timbers commonly used in the United States [4,5]. The analysis of mechanical properties in bamboo species Kao Jue and Mao Jue usually used in Hong Kong and Southern China concluded that they are good construction materials with excellent mechanical properties against compression and bending [6].…”

Abstract:The estimation of heat conduction properties has considerable importance in the characterization of bamboo with respect to its potential use as an alternative construction material. Even though traditional methods such as hot plates have successfully measured thermal parameters, like thermal diffusivity and conductivity in bamboo samples, it is still necessary to transform the cylindrical bamboo specimen into a piece with special geometry and size. This requirement makes this method impractical in applications where several bamboo specimens need to be measured in their original cylindrical shape. This paper presents the estimation of thermo-physical parameters k and ρc p in Guadua angustifolia kunth (Guadua a.k.) bamboo through nonlinear least square optimization and infrared thermography. A sensitivity analysis was carried out to determine how the temperature on the bamboo surface is affected by changes in the convection coefficient h, thermal conductivity k, and volumetric heat capacity ρc p . In spite of the nonlinearity and high correlation in the parameters of the inverse heat conduction problem (IHCP), the estimation of such parameters is robust and consistent with those reported in the literature.
