Abstract	Guadua angustifolia Kunth (Guadua) is a bamboo species native to South and Central America that has been widely used for structural applications in small and large scale buildings, bridges and temporary structures. Guadua remains a material for vernacular construction associated with high levels of manual labour and structural unpredictability. The aim of this work is to develop standardised industrial structural products from Guadua and to measure and predict their mechanical behaviour. Cross laminated Guadua (CLG) panels comprised of three and five layers were manufactured and their mechanical properties evaluated by testing large specimens in compression. The digital image correlation (DIC) method was applied to measure strain variations in the X, Y (in-plane) and Z (out of plane) axes on the surface of 600 mm2 CLG panels. Strain results were analysed using VIC 3D software and used to calculate the elastic properties of the panels. Moduli of elasticity (MOE) values from DIC for three and five ply panels were 13.50 GPa and 22.59 GPa in the principal direction (E0) and 5.28 GPa and 12.54 GPa in the transverse direction (E90). Predicted MOE values for three and five ply panels were 20.76 GPa and 18.77 GPa in the principal direction (E0) and 10.80 GPa and 12.79 GPa in the transverse direction (E90). Results from predictions and DIC analysis were compared and a finite element (FE) model developed to predict the response of the CLG panels under similar load conditions. Overall, this study provides guidelines for structural design with engineered bamboo products which are of key importance for their mainstream use.
