ABSTRACT
In this paper we present a study of the performance of sparse iterative solvers regarding the solution of three-dimensional and non-linear problems encountered in soil/structure interaction. It is composed of two parts. In the first one, we present briefly iterative methods and preconditioners used in this study, then we analyze their performance on two soil/structure interaction problems: a shallow foundation under a vertical loading and a single pile subjected to a lateral loading. Tests are performed assuming an elastic-perfectly plastic constitutive law for the soil material with a non-associated Mohr-Coulomb flow rule .
