The enhancement of mechanical properties in existing timber structures is becoming increasingly common. Numerous studies have explored the use of FRP materials as reinforcement in timber construction. FRP has gained prominence due to its lightweight nature and exceptional mechanical performance, particularly in terms of strength and stiffness. The choice of reinforcing material in timber structures is significantly influenced by the type of fibres used in the composite material. Currently, the market offers FRP materials made from synthetic fibres, natural fibres, and more recently, hybrid fibres, which combine both types. In this paper is presented experimental program of reinforced glulam beams with CFRP stripes. Glulam beams were manufactured in Bosnia and Herzegovina at KrivajaZavidovići. CFRP reinforcement percentage was 0,78%. The result that was obtained by this research show increment in load bearing capacity by 67,84%.
