Effect of near-fault ground motion with pulse signal on dynamic response of dam-reservoir-foundation systems

This paper aimed to determine the effects of a pulse signal near-fault ground motion on dynamic response gravity dams, including dam-reservoir-foundation interaction, using different reservoir modelling approaches such as Westergaard, Lagrange, and Euler. As case study, Sarıyar concrete dam located Sakarya River, 120 km northeast Ankara, was considered for investigating ground-motion responses. First, main principles basic formulations these were presented. Then, finite element models realized considering interaction ANSYS software. To structural under motion, linear transient analyses performed 1999 Taiwan Chi-Chi 1979 Imperial Valley motions, which display apparent velocity pulses representative earthquakes. Subsequently, characteristics compared demonstrate fluid domain effects.
