许多物理模型试验研究了摇摆基础在循环和地震荷载作用下的性能。这些测试在模型尺寸、测试设备、上部结构特性、基脚形状、支撑土壤环境和加载协议方面各不相同。“FoRCy，Foundation Rocking database of Cyclic and Monotonic Loading”是一个新的数据库（发布于https：//www.unitenterhub.org/），总结了摇摆基础的单调和慢循环加载测试的结果。该数据库包括列识别测试设备和设施，土壤，上部结构和系统属性，以及加载协议和结果。数据库包含456条记录（行），每条记录在模型配置或加载幅度方面都是唯一的。为了说明它的价值，本文显示了（1）沉降，旋转和安全系数之间的相关性与承载力和（2）的时刻和累积旋转浅基础。数据表明，动员力矩容量所需的旋转对于广泛的实验来说是惊人的恒定的（约0.01弧度）。
Many physical model tests have examined the performance of rocking foundations during cyclic and seismic loading. These tests varied in model size, testing equipment, superstructure properties, footing shape, supporting soil environment, and loading protocol. “FoRCy, Foundation Rocking database of Cyclic and Monotonic Loading” is a new database (published at https://datacenterhub.org/), summarizing the results of monotonic and slow-cyclic loading tests of rocking foundations. The database consists of columns identifying testing equipment and facility, soil, superstructure, and system properties, as well as loading protocol and results. The database contains 456 records (rows), each one being unique in either model configuration or loading amplitude. To illustrate its value, this article shows correlations between (1) settlement, rotation, and factor of safety with respect to bearing capacity and (2) moment and cumulative rotation for shallow footings. Data indicate that the rotation required to mobilize the moment capacity is surprisingly constant (about 0.01 radians) for a wide range of experiments.
