LEAP projects: Concept and challenges

The Liquefaction Experiment and Analysis Project (LEAP), an international research collaboration among researchers from the US, UK, Japan, China and Taiwan, is a validation campaign to assess the capabilities of existing numerical/constitutive models for liquefaction analysis by using laboratory experiments and centrifuge tests. The nature, goals, and scope of the project are presented in this paper. The goals of the planning phase of the project that is currently ongoing in the US are briefly discussed. The main components of the validation campaign and their corresponding challenges are outlined. © 2015 Taylor & Francis Group, London
