3D interaction mechanisms of a surface foundation subjected to strike-slip faulting

Strike-slip faulting and its interaction with foundation-structure systems has received limited attention, due to the problem’s complexity and the need for 3D analysis. Employing centrifuge modelling (@Rensselaer Polytechnic Institute), Agalianos et al. (2021) identified the key interaction mechanisms and thoroughly validated the recently developed MC-HS model, which incorporates post-​yield isotropic frictional hardening and softening. The MC-​HS model covers the entire range from elastic to fully-​softened response, capturing the deviatoric and volumetric behaviour of dense sand, and its pre-​softening volumetric response, which is crucial for simulation of complex mechanisms of strike-​slip faulting such as Riedel shears.
