The manufacture and use of glued-laminated timber (Glulam) have been consolidated for a long time in European and North American countries, where pine wood has been used to supply the construction market with structural elements. The aim of this study was to evaluate the physical and mechanical properties of Eucalyptus sp. wood, for the production of Glulam elements glued with adhesives based on resorcinol-phenol-formaldehyde (RPF) and polyurethane (PUR). From specimens obtained from Glulam elements, the mechanical resistance to parallel compression efforts on fibers, normal fiber compression, shear on glue lines were investigated; and the comparison of results with specimens from solid wood, the assessment of glue lines efficiency through the delamination test, and penetration of adhesives in wood. Glued timber with RPF presented thicker glue line, less delamination in the glue line, and a larger shear resistance, compared to the beams glued with PUR. Thus, it was possible to conclude that Eucalyptus sp. wood associated with the RPF adhesive has great potential in the manufacturing of Glulam, especially for outdoors subjected to undesirable weather.
