NCU-A2 and NCU-B - National Central University Experiments
收藏资源简介：
Building upon the database of LEAP-UCD-2017, twenty centrifuge model tests of liquefaction and lateral spreading are shared and compared in this archive. Some of the experiments were conducted according to the conventional centrifuge scaling laws; others were conducted according to a generalized scaling law. Please see the general report section of the published project for an overview comparison and background of all of the experiments. 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 the model tests is published as ten separate experiments in this archive (one experiment per centrifuge facility). Each "experiment" includes one or more 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 ten 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), Tokyo Institute of Technology (Japan) and Zhejiang University (China).
本数据集依托LEAP-UCD-2017数据库，在本归档库中共享并对比了20组针对液化与侧向扩展的离心机模型试验。部分试验遵循常规离心机相似律开展，其余试验则采用广义相似律进行设计。如需了解所有试验的背景信息与整体对比情况，请查阅已发布项目的总报告章节。总报告章节中呈现的对比内容可作为检索索引，协助用户快速定位感兴趣的单组试验。 本归档库将模型试验数据整理为10组独立试验（每家离心机机构对应一组试验），每组‘试验’包含1项及以上模型试验，而每项模型试验则包含1至3次破坏性振动加载过程。 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°的渥太华F-65砂沉积层。试验覆盖了多组地震动强度与相对密度工况，旨在明确响应的中位值以及响应对相对密度和振动强度的敏感性。 参与本试验项目的10家离心机试验机构分别为：英国剑桥大学、日本爱媛大学、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、美国伦斯勒理工学院（RPI）、美国加州大学戴维斯分校（UC Davis）、日本东京工业大学以及中国浙江大学。
