Abstract

Earthquake disasters can cause serious damage to buildings. Reasonable seismic performance assessment and effective reinforcement measures can ensure the seismic safety of existing buildings. This paper summarizes the main factors affecting the seismic performance of buildings, including structural systems, materials, foundations, and structural regularity. On this basis, five recommendations are proposed: strengthening seismic performance assessment, improving reinforcement methods, promoting the application of seismic isolation and energy dissipation technologies, emphasizing engineering quality control, and enhancing structural health monitoring. The study shows that accurate assessment based on seismic performance, combined with multiple reinforcement methods, is an essential approach to improving the overall seismic performance of buildings and building resilient cities.
