Study of the influence of the foundation and the reservoir on the dynamic response in a concrete gravity dam profile

abstract: This work aims to verify the influence of foundation and reservoir on dynamic behavior concrete gravity dams in terms natural frequencies, vibration modes for a free analysis; maximum displacements stresses at singular points structure seismic excitation. The dam-reservoir-foundation interaction was investigated through modal transient analysis by finite element method via ANSYS APDL software. For this study, we used typical Brazilian dam profile compatible data from earthquake results showed frequencies coupled system, as well its repercussions response under
