Abstract
The nonlinear dynamic analysis was carried out by extending the lattice model analysis. The purpose of this study is to simply estimate the behavior of reinforced concrete piers subjected to seismic loading. The targets of the analysis are the reinforced concrete piers designed by 4 major international seismic design codes. The nonlinear static and dynamic analyses were performed. The analytical results on the maximum displacement response and maximum capacity obtained by the lattice model were compared with those by finite element analyses. As the result, the prediction according to the lattice model was confirmed to be equivalent to that by FEM. Finally, the virtual seismic wave was input, and the mechanical behavior of designed RC piers was evaluated.
