ABSTRACT
With the acceleration of urbanization and the improvement of construction industrialization, prefabricated buildings have attracted widespread attention due to their advantages of efficiency, environmental friendliness, and economy. However, their seismic performance remains a critical research topic in the engineering field. To enhance the safety and reliability of prefabricated building structures under seismic actions, this study systematically investigates their seismic performance and proposes optimized design methods. Based on domestic and international standards and research findings, combined with numerical simulations and experimental analyses, typical prefabricated building structures were selected as research subjects. Through finite element modeling and dynamic time-history analysis, the influence mechanisms of joint connection methods, component material properties, and structural systems on overall seismic performance were thoroughly explored. Additionally, addressing the weak points in current seismic design for prefabricated buildings, improved joint connection configurations and optimized structural layout schemes were proposed. The study demonstrates that the adoption of new energy-dissipating seismic joints can significantly enhance the ductility and energy dissipation capacity of the structure. Moreover, the optimized structural system exhibits superior stability and anti-collapse performance under seismic actions. Furthermore, this study develops an evaluation method tailored for the seismic design of prefabricated buildings, providing theoretical support and technical guidance for practical engineering applications. This research not only deepens the understanding of the seismic performance of prefabricated buildings but also offers significant references for promoting the sustainable development of construction industrialization, showcasing notable academic value and engineering significance.
