This thesis presents the analyses carried out to compute the Dynamic Soil-Structure Interaction (DSSI) effects of the embedded control tower at Success Dam, California. The particular case of the Success Dam in Sacramento, California was chosen because the control tower at this dam is partially embedded in its upstream slope. The analyses carried out included two dimensional plane strain models based on finite element and explicit finite difference formulations. Several 2D models were analyzed including models with and without the control tower, with and without the intake pipe, with different elastic properties, and incorporating soil nonlinearity using the equivalent linear method. The 3D effects involved in the problem were also studied. This was done by using 3D models and the finite elements formulation. The results obtained herein were compared with previous studies, and conclusions were drawn and recommendations for future work were provided.
