Throughout history, wood has been recognized as one of the most ancient construction materials. Wood material is used in a wide variety of fields due to its many positive properties. Despite its extensive use and distinct characteristics, it does have certain weaknesses, particularly in terms of being relatively brittle, especially under bending forces. To enhance its performance and reinforce wooden structural components, a viable solution is to incorporate FRP (Fiber-Reinforced Polymer) components, which are commonly utilized in rehabilitation processes. The versatility and ease of application with various materials like concrete, wood, and steel have facilitated the enhancement of structural elements' strength and ductility. In recent years, fiber-reinforced polymers have been widely used to strengthen wooden structures. In this study, the effect of FRP reinforcement number on the bending properties of glulam beams obtained from chestnut tree species was investigated. Chestnut beams were reinforced with 1, 2 and 3 layers of FRP. The beams were subjected to the bending test. After the bending test, the maximum load carrying capacity, bending strength and modulus of elasticity values were examined. Obtained findings showed that flexural properties increased with strengthening. In addition, with the increase in the number of reinforcements, the maximum load carrying capacity, modulus of elasticity and flexural strength values increased.
