Abstract
Reinforced concrete (RC) structures form the backbone of modern infrastructure due to their robustness, durability, and versatility. However, in seismically active regions, traditional RC buildings often suffer severe damage due to inadequate ductility, poor detailing, and aging construction practices. Over the past few decades, Fiber Reinforced Polymer (FRP) composites have emerged as an effective retrofitting solution to enhance the seismic performance of existing RC structures. FRP materials offer high strength-to-weight ratios, corrosion resistance, ease of installation, and minimal architectural disruption, making them ideal for seismic strengthening applications.
This research article presents a comprehensive assessment of the seismic performance of RC structures retrofitted with FRP composites. It synthesizes existing literature, outlines the fundamental requirements and design methodologies, discusses system implementation strategies, and evaluates seismic testing outcomes. The article also highlights critical performance indicators such as energy dissipation, stiffness retention, inter-story drift reduction, and failure modes. Findings indicate that FRP retrofitting significantly improves structural behavior under seismic loading, provided that design and implementation follow best practices. Finally, the article identifies key challenges and future research trends in FRP-based seismic retrofitting.
The effectiveness of FRP composites depends on factors such as material selection, bonding techniques, and the quality of surface preparation. Proper detailing and anchorage are essential to ensure the durability and reliability of the retrofit under cyclic seismic loads. Additionally, integrating monitoring systems can enhance the assessment of structural health and guide maintenance strategies post-retrofitting.
