Abstract
Much of the reported research on the dynamic analysis of pile foundations assumes linear behavior of soil that may not be valid at strong excitations. In this paper material nonlinearity of soil caused by plasticity and work hardening is considered for the dynamic analysis of pile foundations. An advanced plasticity based soil model, HISS, is incorporated in a finite element technique. Analysis is carried out in the time domain. The algorithm is verified with available analytical results and then linear and nonlinear responses of a single end bearing pile are compared. Effects of different frequencies of excitation (harmonic) and ratio of rigidity of soil and pile have been investigated.
