Quasistatic cyclic testing of column-top mounted elastomeric bearings with applied top rotation

Test of a column-bearing subassembly. Horizontal displacements were applied at the base of the column simultaneously to rotation at the top of the bearing. Displacements and rotations were applied cyclically while axial load was held constant. Testing was done with a natural and a lead rubber bearing, mounted on columns of varying stiffnesses. The data provides information on the decrease in bearing stiffness with increased rotational boundary condition flexibility.

柱-支座子装配体试验。试验过程中，在柱底施加水平位移的同时，于支座顶部施加转角荷载；循环施加位移与转角荷载的同时，保持轴压荷载恒定不变。本次试验分别采用天然橡胶支座（natural rubber bearing）与铅芯橡胶支座（lead rubber bearing），将两类支座安装于不同刚度的柱体上开展测试。本数据集涵盖了支座刚度随转动边界约束柔性程度提升而降低的相关试验数据。
