ABSTRACT
Prefabricated buildings have gained significant attention in the modern construction field due to their efficient construction and environmentally friendly characteristics; however, their seismic performance requires further in-depth research to meet increasingly stringent engineering demands. This study aims to systematically evaluate the seismic performance of prefabricated building structures by integrating experimental investigations with numerical simulations, while revealing the key influencing factors. Typical prefabricated joint forms were selected, and a series of pseudo-static tests were designed and implemented to analyze the effects of different connection methods, material parameters, and construction details on the seismic capacity of the structure. Meanwhile, a refined numerical model based on the finite element method was established, its accuracy was validated, and further simulations of seismic performance under complex loading conditions were conducted. The results indicate that optimized joint designs can significantly enhance the ductility and energy dissipation capacity of the structure, while reasonable construction measures effectively improve the overall seismic performance. Additionally, this study proposes improved seismic design recommendations, providing theoretical support and technical guidance for practical engineering applications. The innovation of this study lies in the first-time comparative analysis of experimental data and numerical simulation results, establishing a seismic performance evaluation system applicable to prefabricated buildings, filling a research gap in this field, and laying the foundation for promoting the widespread application of prefabricated buildings in earthquake-prone areas.
