| Abstract: |
The assembled composite bridge pier with high performance steel (HPS) and ultra-high performance fibre reinforced cementitious composite material (UHPFRC) possess the advantages of factory production and good seismic performance. In order to improve the connection degree and seismic performance of pier-foundation embedded joint in HPS-UHPFRC composite pier, PBL shear connectors and UHPFRC were adopted in the embedded part. Numerical simulation was carried out on the seismic performance of the joint with PBL shear connectors and without the connectors. Besides, the parametric analysis of the main influencing factors was conducted, including the construction of PBL shear connector, embedded depth of the pier and material types of the joint. The influence laws were obtained through the comparisons, and reasonable suggestions were provided for the design of HPS-UHPFRC composite pier-foundation joint. |
