Abstract
The nonlinear earthquake response analysis for RC bridge piers was conducted for the purpose of verifying the validity of the static and dynamic lattice model considering the buckling evaluation of reinforcing bar. The buckling behavior of reinforcing bar is represented by a spatially averaged stress-strain relationship for reinforcing bar in compression. It has been confirmed that the static lattice model analysis considering the buckling can accurately predict the behavior of RC bridge piers. By the dynamic lattice model analysis considering the buckling, it has been found that the post-peak behavior can be captured with an appropriate accuracy as well as the static analysis in which two different types of earthquake motion were used for the verification of seismic performance of RC bridge piers.
