| Zusammenfassung |
| The present study concerns analysis of the seismic response of earth dams.
The behaviour of both the shell and core of the dam is described using the
simple and popular non associated Mohr-Coulomb criterion. The use of this
constitutive model is justified by the difficulty to obtain constitutive
parameters for more advanced constitutive relations including isotropic and
kinematic hardening. Analyses with real earthquake records show that the
seismic loading induces plasticity in a large part of the shell and in the
lower part of the core. Analysis shows that plasticity should be considered
in the analysis of the seismic response of the dam, because it leads to a
decrease in the natural frequencies of the dam together to energy
dissipation, which could significantly affect the seismic response of the
dam. Plastic analysis constitutes also a good tool for the verification of
the stability of the dam under seismic loading. |
