Abstract A multiscale approach [1] that couples the finite-element method (FEM) and the discrete-element method
(DEM) is employed to model and analyse the earthquake fault rupture-soil-foundation interaction (FR-SFI)
problem. In the approach, the soil constitutive responses are obtained from DEM solutions of representative
volume elements (RVEs) embedded at the FEM integration points so as to effectively bypass the
phenomenological hypotheses in conventional FEM simulations. The fault rupture surfaces and shear
localization patterns under normal faults with or without foundation atop have been well captured by the
multiscale approach and verified with available centrifuge experimental [2] and numerical results [3]. By
