LIQUEFACTION UNDER RANDOM LOADING: UNIT ENERGY APPROACH
Damage to structures resting on loose to medium sandy soils can be severe due to liquefaction triggered by earthquakes. Previous studies involving sinusoidal excitations have validated the use of energy levels to define the onset of liquefaction. The present study extends the use of the energy concept to the kind of random excitations present in an earthquake time sequence. Tests performed on sand specimens under several confining pressures and at different relative densities support this technique, providing a solid and suitable link between laboratory and field behavior.
