“…It can be clearly seen from these studies that the importance of near-fault ground motion effect on the response of the structures have been highlighted. Dynamic responses of dam-reservoir-foundation systems have been investigated using the Eulerian and Lagrangian approaches by many researches [22][23][24][25][26][27][28][29][30][31][32]. In these studies, stochastic and deterministic responses, earthquake analyses, linear and nonlinear behavior of the dams were determined.…”

In this paper, it is aimed to compare the near-and far-fault ground motion effects on the nonlinear dynamic response of dams including damreservoir-foundation interaction. Two different types of dams, which are concrete arch and concrete faced rockfill dams, are selected to investigate the near-and far-fault ground motion effects on the dam responses. The behavior of reservoir water is taken into account using Lagrangian approach. The Drucker-Prager material model is employed in nonlinear analyses. Near and far-fault strong ground motion records, which have approximately identical peak ground accelera-

“…In the studies of fluid-structure interaction systems, major concerns are the analysis of natural and dynamic-response behaviors and the fluid motion suppression for securing the system stability. Here, we can classify the numerical approaches for the free-vibration and dynamic-response analysis into two, the coupled formulation [4,5] and the separate formulation [6,7] using the mass-adding technique. Even though the latter is relatively easier to implement, it is restricted to simple geometry and unsuitable for the problems with excessive flow motion.…”

The aim of this paper is to present accelerations and peak acceleration amplification coefficients in a concrete faced rockfill (CFR) dam. For this purpose, Torul CFR dam is considered by using finite element method. Hydrodynamic pressure of the reservoir water is considered modeled using the fluid finite elements based on the Lagrangian approach. Deconvolution of surface accelerograms is taken into account in numerical solutions. Geometric, material and connection non-linearity are considered in the finite element analyses. The Drucker-Prager model and the multi-linear kinematic hardening model are used for concrete slab and rockfill, respectively, in the materially non-linear analysis. Non-linear behavior of the rockfill is obtained by the uniaxial stress-strain relation. The stress-strain curve of the rockfill is obtained using the shear modulusshear strain relation produced for the gravels. Different joints in the CFR dam are modeled with both welded and friction contacts. The friction in the joints is provided with contact-target element pairs based on the Coulomb's friction law. The accelerations in the bottom and crest of the dam are compared each other since welded and friction contact in dam-foundation interface. Then peak acceleration amplification coefficients are also obtained compared each other. According to numerical comparisons, when the rockfill behaves materially non-linear, the maximum horizontal accelerations and peak acceleration amplification coefficients decrease in the crest.
