Densified lamellas of bamboo Guadua angustifolia Kunth (Guadua) were arranged orthogonally and glued together to form three- and five-layer cross laminated (XLam) panels with symmetrical compositions, which are refereed as G-XLam3 & G-XLam5, respectively. This XLam composition is typical of plywood and cross-laminated timber (CLT) panels, hence analytical design methods developed for these systems have been applied to analyse the structural performance of G-XLam panels. For structural analysis G-XLam panels were considered as multi-layered systems composed of contiguous lamellas with orthotropic axes orientated at 0o and 90o. Timber engineering methods normalised by international standards were used in this study for the prediction of the mechanical properties of G-XLam panels. Bending stiffness proper-ties of these panels were predicted using the transformed cross-section method to find the modulus of elasticity of beams from the moduli of elasticity of the individual layers.
