Abstract: | In this paper, it is aimed to compare the near- and far-fault ground motion effects on the nonlinear dynamic response of dams
including dam–reservoir–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 accelerations, of Loma Prieta
(1989) earthquake are selected for the analyses. Displacements, maximum and minimum principal stresses are determined using
the finite element method. The displacements and principal stresses obtained from the analyses of dams subjected to each fault
effect are compared with each other. It is clearly seen that there is more seismic demand on displacements and stresses when
the dam is subjected to near-fault ground motion. |
