Ground motion effects on a concrete gravity (CG) dam in the earthquake zone should be taken into account for design conditions. Boyabat CG dam constructed in Sinop, Turkey, is selected as an application. This study presents two-dimensional earthquake response of Boyabat CG dam including friction between dam and foundation. The two-dimensional finite element model of Boyabat CG dam is obtained using ANSYS finite element software. The unfavorable section of the dam is selected for two-dimensional numerical analyses. The contact-target element pairs are used in the dam–foundation–reservoir interaction. In this case, friction contact is considered in the numerical solutions. Empty and full reservoir cases are also considered in these solutions. The hydrodynamic pressure of the reservoir water is modeled with two dimensional fluid finite elements based on the Lagrangian approach. In the earthquake analyses, the finite element model has fixed boundary conditions. According to linear dynamic analyses, maximum horizontal displacements and maximum principle stress components are presented by dam height in the largest section. These results are evaluated considering empty and full reservoir conditions.
