Research on Seismic Design and Renovation Strategies of Reinforced Concrete Structures in Civil Engineering

This paper provides a comprehensive review of the seismic design and renovation strategies for reinforced concrete (RC) structures in civil engineering. It begins with an introduction to the importance of seismic design, considering the potential threat of earthquakes to RC structures. It then elaborates on current seismic design codes, principles, and methods, including seismic load calculations, structural system design, and detailing requirements. Retrofit strategies such as reinforcement with fiber-reinforced polymers (FRP), steel sheaths, and seismic isolation techniques were also discussed. Through case studies, the effectiveness of these strategies in improving the seismic performance of RC structures was demonstrated. Finally, the future research directions and challenges in this field are analyzed, aiming to provide a valuable reference for the seismic design and renovation of reinforced concrete structures in civil engineering practice.
