AB The purpose of this work is to study the flexural behaviour of Populus   euroamericana I-214 low-gradeglulam timber beams, internally reinforced with Glass Fibre Reinforced Polymer (GFRP). To this end, 30unreinforced beams and 60 reinforced beams, with two ratios of GRFP reinforcement, were produced and tested. Results show an improvement in the flexural behaviour of reinforced beams, with noticeableincreases in stiffness (MOE) and ultimate moment capacity (MOR). By using relatively low reinforcementratios (1.07%, 1.6%) in the tension zone, we have measured an average improvement of 12.1% and 14.7% in stiffness, and an increase up to 23% in moment capacity. GFRP reinforced seems to reduce the influence of timber heterogeneity and singularities (knots, cracks . . .), which translates into less scattered results and better characteristic values.
