| Résumé: | The paper deals with the numerical analyses carried out on the Oued-Fodda concrete gravity dam
under earthquake shaking with account of soil structure interaction. The seismic behavior of the
dam-soil system is performed by the isogeometric approach based on the NURBS shape functions
and the water mobilized by the dam is modeled with the Westergaard’s mass added approach usually
applied in most of literature studies. The motion equations are solved by the direct integration method
of Newmark. The results are compared with the results obtained by SAP code and other authors
using the finite element method. The effect of soil structure interaction is evidenced by comparing
displacements at the dam crest |
