  • Abstract:
  • The preservation of historic masonry buildings, particularly in seismic-prone areas, presents a significant challenge. Advanced Fiber Reinforced Polymer (FRP) composites have emerged as a promising solution for seismic retrofitting, offering a combination of high strength, low weight, and ease of application without compromising the original architectural aesthetics. This study evaluates the effectiveness of FRP composites in enhancing the seismic resilience of historic masonry structures. Through a comprehensive review of existing literature and case studies, along with experimental investigations on simulated masonry models retrofitted with FRP, the research assesses the performance of these buildings under seismic loading conditions. The outcomes indicate a notable improvement in the seismic behavior of retrofitted structures, including increased deformation capacity, enhanced energy dissipation, and reduced vulnerability to cracking and collapse. The use of FRP composites for seismic strengthening also demonstrates minimal visual impact on the buildings' historic façades, a critical consideration in preservation efforts. Furthermore, the study explores the technical challenges and considerations involved in applying FRP composites to historic masonry, such as substrate compatibility and long-term durability under environmental influences. The findings contribute valuable insights into the viability and limitations of using FRP materials for seismic retrofitting, providing a foundation for developing optimized retrofit strategies that ensure the safety and preservation of historic masonry buildings in earthquake-prone regions.
