The practical method of the seismic damage analysis of high piers of RC bridges is established using the uniaxial modified Faria-Oliver damage model for concrete and modified Menegotto-Pinto model for rebars, based on the fiber beam-column element, in the FEA software ABAQUS. Furthermore, the seismic damage analysis of short pier and high piers of different section sizes are conducted, respectively. The results indicate that for the short piers the damage zone is located at the bottom of piers. However, the high piers tend to have multi-location damage zones, and the tendency is more obvious for the high piers with a more slender shape.
