Strengthening of solid beam with fiber reinforced polymers

Abstract

Timber, concrete and steel are among the traditional building materials used in the construction of buildings. Since concrete is a durable material, it is a building material used in buildings, highways, dams, sidewalks and many other areas. Wood is one of the oldest building materials, and the use of wood and wood-based materials for structural purposes continues to increase. The deterioration of existing wooden structures may result from fatigue and biological attack over time. The cost of replacing the damaged wooden elements is very high, so it seems more appropriate to repair and strengthen the damaged elements. In this study, 20x20x360 mm solid wood beam is reinforced with fiber reinforced polymers and the effect of fiber reinforced polymers on the bending properties of the beam was investigated. In order to determine the bending properties, three-point bending test was applied to the wood beams. As a result of this study, it was determined that the bending properties of wood beam reinforced with fiber reinforced polymer composites were better than the reference samples.
