Description:
As part of the Liquefaction Experiments and Analysis Projects (LEAP - an international collaboration among several institutions with expertise and capabilities in centrifuge modeling, constitutive modeling, and numerical modeling) LEAP-2022 investigated the seismic performance of sheet pile walls in liquefiable soils. The results of twenty centrifuge model tests, performed as part of a round robin test program, are shared in this archive. The datasets produced by the model tests are published as six separate experiments in this archive (one experiment per centrifuge facility). Each "experiment" includes a few model tests and each model test includes between one and three destructive shaking events. All of the tests modeled a sheet pile wall supporting a liquefiable soil (Ottawa F-65 sand and Silica sand). The tests covered a range of ground motion intensities and a range of relative densities to define the median response and the sensitivity of the response to relative density and shaking intensity. The six centrifuge facilities involved in this test program included Ehime University (Japan), Korea Advanced Institute of Science & Technology (ROK), National Central University (Taiwan), Rensselaer Polytechnic institute (USA), University of Cambridge (UK), and Zhejiang University (PRC). For each "experiment", a presentation file (video), prepared for LEAP-GWU-2022 workshop, is also included. The presentations describe the centrifuge experiments in each participating centrifuge facility and the observed responses in details. A Web application for visualization of LEAP-GWU-2022 centrifuge data and their comparisons with user-generated numerical simulations is provided in the Code Project (PRJ-4245) published in Design-Safe.
