We describe two experiments performed on a 9-m-radius geotechnical centrifuge to evaluate dynamic soil–structure interaction effects on the cyclic failure potential of fine-grained soil. Each experiment incorporated three different structures with a range of mass and stiffness properties. Structures were founded on strip footings embedded in a thin layer of sand overlying lightly overconsolidated low-plasticity fine-grained soil. Shaking was applied to the base of the model container, consisting of scaled versions of recorded earthquake ground motions, sweep motions, and step waves. Data recorded during testing were processed and published on the platform DesignSafe. We describe the model configuration, sensor information, shaking events, and data processing procedures and present selected processed data to illustrate key model responses and to provide a benchmark for data use.

我们描述了在9米半径的岩土离心机上进行的两个实验，以评估动态土-结构相互作用对细粒土循环破坏潜能的影响。每个实验都包含具有质量和刚度特性范围的三种不同结构。结构建立在条形基础之上，条形基础埋在薄薄的覆盖于低固结的低塑性细粒土壤上的薄沙层中。将振动应用于模型容器的底部，该容器由记录下来的地震地面运动，扫掠运动和阶梯波的缩放版本组成。测试期间记录的数据已处理并发布在DesignSafe平台上。我们描述了模型配置，传感器信息，震动事件，
