Laminated bamboo was created to standardize the raw material in order to increase its strength, control its shape and develop sustainable and innovative structural elements. Bamboo is a Functionally Graded Material (FGM) due to the progressive distribution of the fibers across its wall thickness. This research presents the results of an experimental investigation series in which bamboo culm, of Dendrocalamus giganteus, was divided into 6 segments of analysis. Three divisions along its length, bottom, middle and top, and then two divisions across its wall thickness, inner and outer. In the first series, the specimens of each segment were tested separately to establish their tensile modulus of elasticity Et. Six types of bamboo uniaxial-laminated beam specimens of 2.5 cm width, 5cm height and 50 cm length were assembled with layers from each particular segment of bamboo culm, using resin of mamona adhesive. Four point bending tests were conducted on beam specimens to establish the bending modulus of elasticity Eb. Experimental values of both specimen groups were compared to those of theoretical values, applying solid mechanics theory. The results provide information to improve the segment arrangement of bamboo-laminated beams upon subjection to bending loads. Based on the results, it is also possible to introduce equivalent values for the analysis of the mechanical properties of the beams, using solid mechanics theory.
