摘要

To address local concrete damage in joint areas at the footing of prefabricated assembled self-centering bridge piers (PASPs) in seismic design, a damage transfer configuration (DTC) was proposed, based on the bridge pier structure configuration and the mechanism of local damage formation. Integrating the DTC into the PASP, numerical models of a previous experimental reference PASP and a PASP with damage transfer configuration (DTPASP) were established using the finite element software ABAQUS with a concrete damage plasticity (CDP) model. The models were then compared with experimental results regarding damage distribution, hysteresis curves, energy dissipation capacity, the joint opening degree, and residual displacement. The findings indicate that the finite element model developed in this study can well reflect the experimental results of the reference PASP. The incorporation of the DTC proved to be beneficial in preserving structural integrity, bearing capacity, and the functionality of the core structure of bridge piers following an earthquake. Meanwhile, this addition did not exert a significant influence on the seismic behavior of the core structure of the bridge pier.
