In order to understand the seismic performance of weir structure under seismic events, concrete weir structure with infinite foundations was modeled in ABAQUS. Additionally, this study conducted the three different design response spectra based on KBC 2009, ASCE 7-05, and EuroCode 8. The results from numerical analyses showed that the seismic behavior of weir structure subjected to seismic ground motions was sensitive to natural frequency and mass participation factors.
