This study presented the seismic performance of weir structures with infinite foundations subjected to seismic ground motions, rather than finite soil foundation to avoid the reflection of seismic wave propagation at the mesh boundaries. The analytical model of weir structures was developed in ABAQUS　platform and then the seismic performance of concrete weir structure was evaluated through design response spectrum (KBC 2009). It was revealed that the maximum stresses obtained from infinite models was significantly increased, in comparison to the finite models.
