IFSTTAR1, IFSTTAR2 - IFSTTAR Experiments, in PRJ-1843: LEAP-UCD-2017

Twenty-four centrifuge model tests of liquefaction and lateral spreading, performed as part of a round robin test program, are shared and compared in this archive. Please see the general report section of the published project for an overview comparison and background of all of the experiments. One document in the report (with “ReadMe” in the file name) describes the organization of the data archive. The comparisons presented in the general report section will serve as an index to help the users find individual experiments of interest. This data from 24 model tests is published as nine separate experiments in this archive (one experiment per centrifuge facility). Each "experiment" includes two or three model tests and each model test includes between one and three destructive shaking events.
All of the tests modeled a 4 m thick deposit of Ottawa F-65 sand with a 5-degree surface slope in a rigid box. 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 nine centrifuge facilities involved in this test program included Cambridge University (UK), Ehime University (Japan), IFSTTAR (France), NCU (Taiwan), KAIST (Korea), Kyoto University (Japan), RPI (USA), UC Davis (USA), and Zhejiang University (China).

本数据集档案共享并比对了作为循环比对试验计划（round robin test program）一部分开展的24组液化与侧向扩离（liquefaction and lateral spreading）离心机模型试验。请参阅已发布项目的总报告章节，以了解所有试验的概况比对结果与研究背景。报告中文件名包含"ReadMe"的文档，说明了本数据档案库的组织架构。总报告章节中呈现的比对结果将作为索引，帮助使用者检索感兴趣的单组试验。
本档案库将24组模型试验的数据以9组独立试验的形式发布（每家离心机机构对应一组试验）。每组"试验"包含2至3组模型试验，而每组模型试验包含1至3次破坏性振动工况。所有试验均在刚性箱体内模拟了厚度为4米、表面坡度为5度的渥太华F-65砂（Ottawa F-65 sand）沉积层。试验涵盖了一系列地震动强度与相对密度工况，以明确响应的中位值，以及响应对相对密度与振动强度的敏感性。参与本试验计划的9家离心机机构包括：英国剑桥大学（Cambridge University）、日本爱媛大学（Ehime University）、法国IFSTTAR、中国台湾地区中央大学（NCU）、韩国科学技术院（KAIST）、日本京都大学（Kyoto University）、美国伦斯勒理工学院（RPI）、美国加州大学戴维斯分校（UC Davis）以及中国浙江大学（Zhejiang University）。
