چکیده
|
In this paper, the dam body and the underneath soil were modeled using coupled finite-infinite elements under plane strain conditions. initially, static stresses developed in the dam-foundation system due to gravity and hydrostatic loads are evaluated. elasto-plastic seismic analysis of the dam-foundation system is next carried out by adopting the drucker-prager criterion for the material nonlinearity. the equation of motion is solved by newmark incremental time integration technique. the study focuses on the structural behaviour of the dam-foundation system under earthquake excitations. the behaviour in terms of displacement contours, stress distributions and the failure mode are presented.
