一些实验研究表明，摇摆浅基础具有有益的抗震性能特征：重定中心和能量耗散，几乎没有损害。一个新的公开数据库，“FoRDy”（基础摇摆动力），总结了单自由度的摇摆基础上支持的结构的动态物理模型试验的结果。它包含了在美国、希腊和日本的实验设施中进行的五个离心机和三个1-g振动台试验系列的数据。该数据库包括200个模型“案例历史”，涵盖了广泛的模型尺寸、土壤和结构特性以及地震激励。这是建立一个全面的动态摇摆基础数据库的第一步，它有潜力在未来发展。为了说明它的有用性，数据被用来显示示例之间的相关性的峰值漂移比的需求和选定的地面运动强度的措施。结果表明，峰值地面速度（PGV），峰值地面位移（PGD），和线性谱位移的几何平均值在0.2-3倍的初始自然周期范围内预测的峰值漂移比响应可靠。
Several experimental studies have shown that rocking shallow foundations have beneficial seismic performance features: recentering and energy dissipation with little damage. A new publicly available database, “FoRDy” (Foundation Rocking—Dynamic), summarizes the results of dynamic physical model tests of single-degree-of-freedom-like structures supported on rocking foundations. It contains data from five centrifuge and three 1-g shaking table test series that were conducted at experimental facilities in the United States, Greece, and Japan. The database includes 200 model “case histories” that span a wide range of model sizes, soil and structure properties, and seismic excitations. It is compiled as the first step toward building a comprehensive dynamic rocking foundation database, and it has the potential to grow in the future. To illustrate its usefulness, the data are used to show example correlations between the peak drift ratio demand and selected ground motion intensity measures. The results suggest that peak ground velocity (PGV), peak ground displacement (PGD), and the geometric mean of the linear spectral displacement over the period range of 0.2–3 times the initial natural period predict the peak drift ratio response reliably.
