Abstract
In order to clarify the seismic performance of reinforced concrete (RC) bridge piers under seismic loading, the computing program using the lattice model, which is an analytical model for determining the change in the shear resisting mechanism, has been developed. By the comparison between the experimental and analytical results, it has been confirmed that the static lattice model analysis can predict the load-carrying capacity and the ductility of RC bridge piers subjected to cyclic loadings. In addition, by the comparison between the results obtained by the shaking table tests and the dynamic lattice model analysis, it is found that the dynamic behavior of RC bridge piers subjected to ground motion can be appropriately evaluated. Finally, it has been proved that the influence of the transverse reinforcement on the seismic performance can be properly estimated in terms of the energy absorption of RC bridge piers.
