Abstract EN
Possible base sliding induced by an earthquake on concrete gravity dams is obtained by a simplified procedure.
The model is a nonlinear single-degree-of-freedom system which takes into account dam-water-foundation interaction based on the model developed by Fenves and Chopra (1987).
The nonlinearity is in the foundation rock, since a threshold value for the sliding foundation resistance, modeled with the Mohr-Coulomb yielding criterion including a frictional and a cohesive component, is imposed.
Nonlinear step by dams is obtained by a simplified procedure.

Nonlinear step by step dynamic analyses are carried out on four case studies representing typical examples of Italian concrete gravity dams by utilizing several natural earthquakes.
On the basis of the obtained results, a simplified methodology to estimate residual displacement without performing nonlinear dynamic analysis is presented.
An example of application using as seismic input the elastic response spectra furnished by the Italian Code is also presented.
