  • Abstract:
  • The long-term durability of Fiber Reinforced Polymer (FRP) systems as a solution for the strengthening of masonry structures is critically examined under the influence of various environmental stressors. This study investigates the performance and resilience of FRP retrofitting techniques when exposed to UV radiation, moisture, temperature fluctuations, and chemical degradation over extended periods. By synthesizing data from accelerated aging tests, field studies, and literature reviews, the research highlights the vulnerability of FRP materials to environmental conditions and their potential impact on the bond strength, stiffness, and overall structural integrity of retrofitted masonry. Furthermore, the study explores mitigation strategies, including the use of protective coatings and the development of new FRP composites designed for enhanced environmental resistance. The findings aim to inform the selection of FRP systems for masonry strengthening, ensuring long-term durability and reliability.
