This paper presents an extension of the domain reduction method (DRM) to deal with dynamic coupled consolidation problems. The DRM, developed by Bielak et al. ( Bull. Seismol. Soc. Am. 2003; 93 (2): 817–824), is a two‐step procedure that aims at reducing the domain that has to be modelled numerically by a change of governing variables. The seismic excitation is directly introduced into the computational domain and an artificial boundary is needed only to absorb the scattered energy of the system. The extended formulation of the DRM is presented and validated for linear and nonlinear analyses in a boundary value problem. Copyright © 2007 John Wiley & Sons, Ltd.
