  ABSTRACT: A finite element method based program has been developed to perform the static nonlinear analysis of pile group with six different configurations subjected to lateral loads. The pile has been assumed to remain elastic all the time whereas the soil has been assumed to undergo plastic yielding following von Mises yield criterion. The formulation of elasto-plastic analysis following von Mises yield criterion has been explained. The effect of Drucker-Prager and Mohr Coulomb yield criteria on the response of pile group is also investigated. The whole analysis is based on incremental load application. The external load is applied in small increments and the stresses are initially computed assuming elastic constitutive relation. Significant effect of soil nonlinearity is observed at smaller pile spacing which reduces with increase in spacing.
