Abstract (EN): An in-house soil liquefaction assessment tool using a CPT-based simplified procedure has been developed using MathCad in order to investigate the capabilities and limitations of three commercially available software packages, namely CLiq, LiquefyPro and Settle3D. The validation is carried out using three high quality CPT measurements from the New Zealand Geotechnical Database, selected as to include locations characterized by none, minor and major liquefaction, based on post-earthquake observations. The performance of each software package is assessed by comparing results in terms of factor of safety against liquefaction and estimating liquefaction-induced settlements. The benchmarking exercise against well-documented case histories of liquefaction helped to identify inherent differences among the software packages and the effect of those in the assessment of liquefaction and the estimation of liquefaction-induced settlements. The study highlighted the benefits of having a custom-made in-house tool to assess soil liquefaction, flexible to adaptation and updates as new techniques become available. © 2019 Associazione Geotecnica Italiana, Rome, Italy.
