Abstract
Enhancement of timber beams by means of natural and synthetic reinforcement. This work compares the effectiveness of local reinforcements of pine beams. Test beams were reinforced with CFRP strip (Carbon Fiber Reinforced Polymer) and LLBC (Layered Laminate Bamboo Composite). Beams were tested to determine bending strength in accordance with the EN 408 (2012) standard. On the basis of testing and calculations, it was concluded that local reinforcement with both reinforcing materials caused a significant (p < 0.05) gain in bending strength. LLBC as a renewable, natural material is a valuable alternative to the synthetic, highly processed materials such as CFRP strip. It is necessary, however, take into account that defects of the structure adversely affect its strength.
