Soil liquefaction continues to cause devastating damage to the built environment during earthquakes. In recent years, earthquakes in Christchurch-New Zealand (2010-2011), Tohoku-Japan (2011), Muisne-Ecuador (2016), have caused widespread liquefaction resulting in unacceptable settlement, tilt and deformation of buildings, especially those on shallow foundations. Field observations from such events provide valuable information about the behavior of soil and the response of structures, but a scarcity of instrumentation means that detailed recordings of the soil and structure responses from the time of the earthquake are lacking. Data is especially sparse regarding the performance and effectiveness of liquefaction mitigation strategies. Numerical and experimental studies have been performed at the University of Colorado Boulder to generate new case histories under controlled conditions. This presentation will summarize trends from both physical and numerical models, focusing on how structural performance is affected by some common liquefaction mitigation approaches
