Abstract For a class of civil engineering structures, that can be accurately represented by ‘coupled shear walls’ (CSWs), a discrete model for the analysis of the dynamic interaction with the underlying soil is proposed. The CSWs, with one or more rows of openings, rest on a rigid foundation embedded in the elastic or viscoelastic half‐space. A hierarchical finite element model based on an equivalent continuum approach is adopted for the structure. A frequency‐domain boundary element method is used to represent the half‐space. Finally, the set of equations governing the response of the coupled soil‐structure system to harmonic lateral loads acting on the structure is also given. The frequency deviation effect with respect to the fixed‐base structure and the effects of radiation and material damping in the soil are presented for different characteristics of the structure and different soil properties.
