000010365 520__ $$2eng$$aA new energy based model for the evaluation of liquefaction in cohesionless soils has been proposed. In this model, the amount of the kinetic energy possessed by soil particles during shaking is considered in liquefaction potential assessment. A formulation procedure has been proceeded to reach a closed form relation which yields the maximum kinetic energy dissipated in the unit volume of liquefiable soil layer. Using a certain field liquefaction case histories catalog, acceptable performance of the kinetic energy model in the classification of liquefied and non-liquefied cases has been shown. The classification capabilities of the current model and the shear stress based model proposed by Seed and his colleagues have been compared. It has been found that, although the classification successfulness of the current model and initial form of the stress based method are comparable, additional studies and modifications, the same as those carried out for the initial form of stress method, may be required to improve the performance of the model.
