地震对建筑物及其内容物(例如敏感设备)造成的损坏可能会影响生命安全并在事件发生后扰乱业务运营。地板隔离系统 (FIS) 是保护重要建筑内容的一种有前景的改造策略。在本研究中,利用实时混合模拟(RTHS)来实验性地合并多尺度(建筑-FIS-设备)交互。为此,我们研究了代表基于 FIS 的滚动摆 (RP) 的一个轴承的实验装置 - 首先通过特性测试,然后通过 RTHS。一系列测试是在理海大学自然灾害工程研究基础设施 (NHERI) 实验设施中进行的。使用多重激励来研究单轴加载下的实验装置。介绍了用于表征和 RTHS 测试的实验测试台和测试协议的详细信息,以及这些测试的结果,重点关注不同滚动表面处理对补充阻尼的影响、FIS-设备和建筑物-FIS 相互作用,以及通过 RTHS 对不同 RP 隔震轴承设计的严格评估。
Damage caused by earthquakes to buildings and their contents (e.g., sensitive equipment) can impact life safety and disrupt business operations following an event. Floor isolation systems (FISs) are a promising retrofit strategy for protecting vital building contents. In this study, real‐time hybrid simulation (RTHS) is utilized to experimentally incorporate multi‐scale (building–FIS–equipment) interactions. For this, an experimental setup representing one bearing of a rolling pendulum (RP) based FIS is studied—first through characterization tests and then through RTHS. A series of tests was conducted at the Natural Hazards Engineering Research Infrastructure (NHERI) Experimental Facility at Lehigh University. Multiple excitations were used to study the experimental setup under uni‐axial loading. Details of the experimental testbed and test protocols for the characterization and RTHS tests are presented, along with results from these tests, which focused on the effect of different rolling surface treatments for supplemental damping, the FIS–equipment and building–FIS interactions, and rigorous evaluation of different RP isolation bearing designs through RTHS.
