The most common types of damage that can be expected due to liquefaction are settlement, differential settlement, subsidence and tilting of a structure at the site. The damage criterion related to the differential settlement of foundation is especially addressed in this paper. In this work, a finite element model is developed for evaluating the general characteristics of pore water pressure build-up and dissipation in a saturated sand deposit during and following an earthquake motion. The differential settlement of footings is then determined by evaluating volume changes below the footings caused by pore water pressure dissipation. The influence on the damage assessment of uncertainties in the load and soil parameters is also discussed.
