This research presents a detailed investigation into advanced retrofitting and strengthening techniques for structural timber beams using Fiber Reinforced Polymer (FRP) composites. Despite their historical significance and widespread use, timber structures increasingly face challenges such as aging, material degradation, and the demand for enhanced performance under modern load conditions. The primary objective of this research is to develop and optimise methodologies that improve the mechanical properties of timber beams through the application of FRP composites, with a focus on increasing load-bearing capacity, stiffness, and structural durability.
The research methodology involves a comprehensive experimental program integrated with advanced numerical analyses. Laboratory investigations will include a series of controlled tests to evaluate the performance of timber beams retrofitted with different FRP composite systems under various loading conditions. The experimental results will be employed to validate finite element models (FEM), which will simulate the behaviour of FRP reinforced timber beams and optimise the retrofitting strategies. Additionally, extensive life cycle and cost-benefit analyses will be conducted to assess the sustainability and economic viability of the proposed retrofitting techniques.
The expected outcomes of this research include identifying optimal FRP materials and configurations for strengthening timber beams and developing practical guidelines for their implementation. This study aims to significantly contribute to sustainable construction practices by extending the service life of timber structures, reducing the need for replacement, and supporting circular economy principles. The findings will provide valuable insights for engineers and professionals preserving and enhancing timber structural systems.
