This article presents an analysis of the mechanical properties of Glulam beams reinforced with punched metal plates. In this study, two groups of Glulam beams were fabricated and experimentally analyzed: 30 non reinforced Glulam beams and 30 Glulam beams reinforced with punched metal plates. All Glulam beams were made of Carbonero (Licania campestre) and an epoxy adhesive with high strength and durability. Four-point bending tests in the 60 full-scale beams were carried out. Then, a model based on linear elasticity theory was used to calculate the strength and verify the experimental results. It was determined that Glulam beams reinforced with punched metal plates show a better mechanical behavior than non reinforced Glulam beams. It was further established that the use of punched metal plates increases the homogeneity and the mechanical capacity of Glulam beams.
