Abstract: The segmented bridge piers with post-tensioned prestressed joints have the advantages of short construction period, little impact on the environment and easy quality assurance, but their mechanical properties are still unclear. In order to obtain a prestressed axial compression ratio with good mechanical properties, a five-section assembled bridge pier with a section of assembled bridge piers is designed. The finite element model is built and simulated by ABAQUS. The simulation results are obtained. Comparing with the existing test results, the correctness of the simulation method is verified. Then the influence of different prestressed axial compression ratios on the mechanical properties of the segmented bridge pier is analyzed and compared. The results show that the axial compression ratio is 10%~20%. The structure has good mechanical properties. This research can provide a certain reference for the design of segmental bridge piers.

Key words: prestressed precast segmental bridge piers, pre-stressed axial compression ratios, mechanical performance, ABAQUS
