Soil liquefaction has been observed during the earthquake on May 20, 2012 M5.9 that shock Emilia Romagna (Italy). It is one example of moderate earthquakes yielding extensive liquefaction-related phenomena that induced damage, disruption of function and considerable replacement expenses for structures. The paper aims at simulating the liquefaction effects on an ordinary benchmark residential structure. 3D numerical simulations of the soil–structure system perform a shear-type building based on a non-linear hysteretic soil. The paper applies the open-source computational interface OpenSeesPL, implemented within OpenSees, from the Pacific Earthquake Engineering Research Center. It allows integration of advanced models to investigate challenging numerical simulations of soil–structure interaction with liquefaction.
