Abstract (EN): Earthquake-induced liquefaction is responsible for considerable structural damage. However, conventional liquefaction assessment focuses only on triggering. In this paper, the evaluation of liquefaction is refocused to consider the performance of buildings. A new hazard-independent liquefaction classification is proposed where the soil profile is defined as an equivalent 3-layered soil profile. The classification consists of only three features, highly influential to the performance of buildings: the depth of the non-liquefying crust, and the thickness and liquefaction resistance of the potentially liquefiable layer. The influence of these parameters is explored with reference to changes of the ground surface acceleration and foundation bearing capacity. A procedure to obtain the 3-layered soil profile from CPT data is developed and set of soil profile classes are developed for rapid loss assessment purposes. The procedure and classes are demonstrated on a case study site considering 100 CPT from Christchurch and a comparison is made regarding the computed LSN value for the equivalent and CPT profiles. © 2019 Associazione Geotecnica Italiana, Rome, Italy.
