Abstract
Earthquake disasters cause severe damage to civil engineering structures, impacting socioeconomic stability and the safety of people's lives and property. To enhance the seismic resilience of civil engineering structures, this paper systematically investigates optimization strategies and practical methods for improving structural seismic performance. Based on domestic and international seismic design codes and research findings, a combination of theoretical analysis, numerical simulation, and experimental studies was employed to explore the response characteristics of different structural systems under seismic loading. A comprehensive seismic resilience evaluation system that considers structural ductility, energy dissipation capacity, and reparability is proposed. This study innovatively introduces performance-based seismic design concepts and proposes various measures to enhance seismic resilience for different types of building structures, including base isolation, application of damping devices, and the use of new materials, along with corresponding quantitative assessment models. The effectiveness of these strategies in improving survival capability and rapid recovery function under rare earthquakes, as well as significantly reducing secondary disaster risks, has been validated through applications in typical engineering cases. This research not only enriches the theoretical fr amework of seismic resilience but also provides robust technical support for practical engineering, contributing significantly to the advancement of seismic technology in civil engineering both in China and globally.
