Comparison of near- and far-fault ground motion effect on the nonlinear response of dam–reservoir–foundation systems

摘要: In this paper, it is aimed to compare the near- and far-fault ground motion effects on nonlinear dynamic response of dams including dam–reservoir–foundation interaction. Two different types dams, which are concrete arch faced rockfill selected investigate dam responses. The behavior reservoir water taken into account using Lagrangian approach. Drucker–Prager material model employed in analyses. Near strong records, have approximately identical peak accelerations, Loma Prieta (1989) earthquake for Displacements, maximum minimum principal stresses determined finite element method. displacements obtained from analyses subjected each fault effect compared with other. It clearly seen that there more seismic demand when near-fault motion.
