Seismic performance of prefabricated piers with different connection methods: A literature review

Abstract Bridge prefabrication technology is gaining popularity in the engineering community for its standardized and rapid construction with automatic construction method benefits over in situ casting. Recent advancements in prefabrication assembly technology have led to increased engineering construction of prefabricated assembled bridges. However, determining the seismic performance of prefabricated assembled bridge piers remains a challenge. This article summarizes and compares various connection methods of prefabricated piers, explores their seismic performance, and offers a theoretical foundation for practical engineering. Research indicates that sleeve and grouted ducts connections demonstrate seismic performance comparable to cast‐in‐place piers, but quality control of grouting materials during construction remains a challenge. Prestress connections have low energy dissipation capacity, making them suitable for low‐intensity areas, though improving this capacity with new materials introduces cost concerns. Hybrid connections, which incorporate energy dissipation devices, show promise but are limited by construction complexity and durability issues of external devices. Socket and slot connections, though relatively new and with an unclear force mechanism, have shown seismic performance similar to cast‐in‐place members, meeting seismic code requirements.
