AbstractThis Engineering Research Initiation (ERI) project investigates how simultaneous vertical and horizontal shaking, induced by ground motions during earthquakes, influences the behavior of sandy soils, particularly the triggering of liquefaction and the resulting ground settlement. While most earthquake design methods consider only horizontal shaking, newer data from recent earthquakes show that vertical accelerations can be just as strong, and may significantly affect infrastructure safety.
