In this paper, dynamic response of Concrete Faced Rock Fill Dams (CFRD) are studied with emphasis on the effect of reservoir elevation on the response. The ongoing research regards the dynamic response of CFRD is reviewed. The characteristics of the software used and the method of solution are briefly discussed and the modification applied on the used software (ANSYS) is briefly described. The geometry of the problem and the material characteristics of the CFRD used in the analysis are introduced. It is worthwhile to note that an elastoplastic, critical state, nonassociated material behavior is considered for the rockfill material. Finally, the results of dynamic analysis including modal analysis, response of dam body and response of the concrete face of the dam using modified ANSYS program are presented and discussed. In this paper, the emphasis is put on the effect of reservoir elevation on the dynamic response of CFRD. The results of the analysis indicate that there will be a separation between the rockfill and the concrete slab near the crest resulting in a major uplift in slab during an earthquake when the reservoir elevation is low. Therefore, care should be taken for such a condition.
