In this paper we present a study of the performance of sparse iterative solvers regarding the resolution 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 analyse their performance on three soil/structure interaction problems: a shallow foundation under a vertical loading, a single pile subjected to a lateral loading and the construction of a lined tunnel in a soft soil. Tests are performed assuming an elastic–perfectly plastic constitutive law for the soil material with a non‐associated Mohr–Coulomb flow rule. Copyright © 1999 John Wiley & Sons, Ltd.
