Abstract
Seismic retrofitting of existing buildings is critical to enhance their structural performance and ensure occupant safety during earthquakes. Fiber Reinforced Polymer (FRP) composites have emerged as an effective retrofitting material due to their high strength-to-weight ratio, corrosion resistance, and ease of installation. This paper reviews the use of FRP composites in seismic retrofitting, focusing on their application techniques, effectiveness, and challenges. A comprehensive literature review and statistical analysis of experimental results from previous studies are presented. The methodology includes experimental testing and numerical simulation of FRP-strengthened reinforced concrete (RC) columns and beams. Results indicate significant improvements in load-bearing capacity, ductility, and energy dissipation. Conclusions emphasize the advantages of FRP composites for seismic retrofitting while discussing limitations and future research directions.
