The occurrence of liquefaction during earthquakes can cause significant damage to buildings and infrastructure. The damaging effect of liquefaction is a permanent deformation of the ground, which will either be vertical in level ground, or horizontal (with a vertical component) in sloping ground or in the vicinity of a free face. Buildings in zones of liquefaction are particularly vulnerable to differential ground movements, resulting from the heterogeneity of stratigraphy and soil properties. Many published methodologies are now available for assessing the likelihood and extent of liquefaction occurrence. However, it is equally important to understand how the occurrence of liquefaction will affect the built environment. This paper presents analytical solutions for the assessment of expected structural damage to existing reinforced concrete frame buildings resulting from liquefaction-induced differential ground movements. The methodology is primarily intended for application to assessments of expected earthquake damage and losses to existing buildings, and therefore satisfies the requirements of such studies for a simple, rational approach using easily attainable structural parameters to represent the building stock.

Engineering seismology is an integral part of earthquake engineering, a specialized branch of civil engineering concerned with the protection of the built environment against the potentially destructive effects of earthquakes. The objective of earthquake engineering can be stated as the reduction or mitigation of seismic risk, which is understood as the possibility of losses – human, social or economic – being caused by earthquakes. Seismic risk exists because of the convolution of three factors: seismic hazard, exposure, and vulnerability. Seismic hazard refers to the effects of earthquakes that can cause damage in the built environment, such as the primary effects of ground shaking or ground rupture or secondary effects such as soil liquefaction or landslides. Exposure refers to the population, buildings, installations, and infrastructure encountered at the location where earthquake effects could occur. Vulnerability represents the likelihood of damage being sustained by a structure when it is exposed to a particular earthquake effect.
