- Abstract:
- In order to study the seismic performance of the prefabricated pier connected by Ultra-high performance concrete (UHPC), according to the practical engineering,the finite element model of the prefabricated pier connected by UHPC and the cast-in-place pier have been established by ABAQUS, the seismic performance of the prefabricated pier connected by UHPC and the cast-in-place pier were analyzed. The results showed that the failure process and failure form of the prefabricated pier connected by UHPC were similar to that of the cast-in-place pier, and the seismic performance of the joint between the prefabricated pier bottom and the variable section part should be strengthened. The hysteretic behavior, horizontal equivalent stiffness, energy dissipation, and residual displacement of the prefabricated pier connected by UHPC were basically consistent with the cast-in-place pier, which could satisfy the seismic requirements of the bridge. So UHPC could be used as the filling material for the prefabricated pier joints, which could improve the construction speed by using its good mechanical properties and working performance, thus it could exert the advantages of prefabricated construction technology.
