Abstract：To solve the problems of the existing precast bridge piers including inconvenience of construction, corrosion risk, and insufficiency of earthquake resilient performance, a new re-centering socketed segmental precast pier (RSSPP) was proposed in this paper, based on the advantages of socketed pier and segmental pier. Basalt fiber-reinforced polymer (BFRP) tendons and 2304 stainless steel bars was used in this pier. On the one hand, RSSPP with socketed connection has features of reliable connection, simple onsite construction and large tolerance, on the other hand, the pier has excellent re-centering performance. Two detailed fiber element models of the socketed pier and segmental pier were developed and testified on OpenSees platform. On this basis, seismic performance and parameters analysis of RSSPP were conducted. The results show that BFRP tendons has basically identical performance with steel strand in small displacement. However, the post-yield stiffness of the pier continuously increases with the increase of initial prestress. With the increase of the reinforcement ratio of ED bars, the energy dissipation and horizontal bearing capacity of the pier increase significantly, but re-centering capacity indicated by residual deformation decreases. Thus, a balance between the re-centering performance and energy dissipation capacity need to be considered in practical application.
