Real scale experimental assessment of pile group dynamic impedance (ERIES-RESPOND)

This dataset includes acceleration and displacement recordings of (1) dynamic forced vibration tests of a 2x2 pile group foundation, (2) dynamic forced vibration tests of a prototype structure (EuroProteas) resting on the 2x2 pile group foundation, and (3) displacement recordings for horizontal and vertical static loading of a single pile. The instrumentation comprised high-resolution accelerometers, seismometers, laser displacement sensors. The instruments were placed on the soil, in the piles, at the foundation and at the roof slab of the structure. The dynamic tests covered a wide range of frequencies (1 to 10Hz) and amplitudes (0.1kN to 20kN).

本数据集涵盖以下三类实测数据记录：1. 2×2群桩基础的动态强迫振动试验加速度与位移记录；2. 依托该2×2群桩基础的原型结构（EuroProteas）的动态强迫振动试验记录；3. 单桩在水平与竖向静荷载作用下的位移记录。本次试验所用传感设备包括高分辨率加速度计、地震检波器与激光位移传感器，其布设点位覆盖土体、桩身、基础本体以及结构物顶板。本次动态试验覆盖的频率范围为1Hz至10Hz，荷载幅值区间为0.1kN至20kN。
