Natural Hazards Research Summit 2024: Large-Scale Mobile Shakers and Associated Instrumentation for Dynamic Field Studies of Geotechnical and Structural Systems

The poster for the NHERI Summit explains the NHERI@UTexas facility and highlights six example projects. The three main research areas of NHERI@UTexas are (1) Developing comprehensive 2D/3D subsurface geotechnical imaging for deeper, more accurate, and higher-resolution analyses, (2) Characterizing the nonlinear dynamic response and liquefaction resistance of complex geomaterials in situ, and (3) Creating rapid, in-situ methods for structural health monitoring and soil-foundation-structure interaction (SFSI) studies. The six example projects are related to these three main research areas and primarily utilize the unique tri-axial vibroseis known as T-Rex, which can generate ground motion in three different directions at the push of a button. Additionally, the vibroseis called Liquidator and Rattler are also used for projects. The recorded and analyzed data will be published on DesignSafe for reuse.

NHERI峰会的宣传海报介绍了NHERI@德克萨斯大学（NHERI@UTexas）设施，并重点展示了六个示范项目。NHERI@UTexas的三大核心研究方向如下：（1）开发面向深层、高精度、高分辨率分析的完整二维/三维地下岩土成像技术；（2）表征原位复杂岩土材料的非线性动力响应与抗液化性能；（3）研发用于结构健康监测与土-基础-结构相互作用（soil-foundation-structure interaction, SFSI）研究的快速原位测试方法。上述六个示范项目均围绕这三大研究方向展开，主要依托名为T-Rex的独特三轴振动源开展实验，该设备仅需按下按钮即可生成三个不同方向的地面运动。此外，项目还将使用名为Liquidator与Rattler的振动源。所有录制并经分析处理的数据将发布至DesignSafe平台以供复用。
