Abstract
This study investigates the seismic retrofitting of reinforced concrete (RC) buildings using fiber-reinforced polymers (FRP), focusing on techniques and efficacy available up to 2015. The paper presents a comprehensive methodology, including experimental simulation protocols and statistical analysis, to evaluate improvements in structural performance. Five research objectives guide the inquiry, with a single statistical analysis table summarizing key performance metrics. Simulation research using nonlinear dynamic analysis validates the proposed retrofitting schemes. Results indicate significant enhancements in ductility, strength, and energy dissipation. The findings support the adoption of FRP retrofitting in seismic regions and provide engineering guidelines for implementation.
