摘要：
To reveal the seismic performance of prefabricated piers with different connection forms, relevant research development was systematically reviewed and analyzed. According to the mechanical behaviors, the prefabricated pier systems were divided into emulative and non-emulative systems. The corresponding connection forms, performance, construction characteristics, and engineering examples were introduced. The common manners and research methods for improving seismic performance were summarized. The results show that the emulative system is similar to the cast-in-place system, possessing a strong energy dissipation capacity and being widely used. The non-emulative system features a self-recentering function but the realization is more complicated. The employments of high-performance materials, new devices and hybrid systems can effectively avoid the premature failures of connection joints, thus improving the seismic performance. Theoretical analysis, model test and numerical simulation can effectively reflect the mechanical behaviors of prefabricated piers. Finally, the new challenges in the application of prefabricated piers were put forward. The development prospects of system level analysis, life cycle design, seismic resilience were described, providing references for new research directions. © 2022, Editorial Department of Journal of Southeast University.
