Each far-fault earthquake has different seismic effects on the nonlinear principal stress behaviour of the IlР”В±su CFR dam. It is clearly understood that the nonlinear seismic behaviour of the IlР”В±su dam changes depending on the magnitudes and periods of the far-fault earthquakes. According to the seismic results, the principal stresses for the three critical nodal points on the dam body surface are examined and evaluated in detail. In the numerical analyses, a total of 7 various strong far-fault earthquakes are used for the 3D nonlinear earthquake analyses, and 7 different numerical analyses are performed for the full-reservoir condition of the IlР”В±su CFR dam.

These special damping values are defined to the FLAC3D software using the special fish functions to capture the effects of the variation of the modulus and damping ratio with the dynamic shear-strain magnitude. Moreover, the hysteric damping coefficients are separately calculated for all of the materials. While defining these boundary conditions, the special fish functions are created and defined to the software. In addition, the quiet artificial boundary condition is used for the bottom of the foundation. The free-field boundary condition that is a very important boundary condition for the nonlinear seismic analyses is considered for the lateral boundaries of the 3D model. These boundary conditions are free-field and quiet boundary conditions. Very special seismic boundary conditions rarely used for CFR dams in the past are used in this work. Moreover, the concrete slab is modelled considering the DruckerРІР‚вЂњPrager nonlinear material model to represent the nonlinearity of the concrete. The MohrРІР‚вЂњCoulomb nonlinear material model is used for the rockfill materials and foundation. Therefore, the special interface elements are defined between the dam body, concrete slab, and foundation to represent the interaction condition. The dam body, foundation, and concrete slab constantly interact during the lifetime of the CFRDs. The 3D finite difference model of the IlР”В±su dam is created using the FLAC3D software based on the finite difference method. In this study, three-dimensional (3D) seismic behaviour of the IlР”В±su dam built on the East Anatolian Fault (EAF) line is examined considering the effect of the important various far-fault earthquakes. For this reason, the nonlinear earthquake behaviour of these dams should be constantly observed taking into account the seismicity of the zone.

Examination of the seismic behaviour of a CFR dam built on the seismic zone is very important to assess the safety and future of the dam. In the recent times, many huge concrete face rockfill dams (CFRDs) have been modelled and constructed in the world, and many of these dams are located on the strong earthquake zones.
