Field Vibration Testing and Analytical Studies of a Four-Story RC Building (NEES-2011-1074)

<p><strong>Title</strong>: Field Vibration Testing and Analytical Studies of a Four-Story RC Building (NEES-2014-1074)</p> <p><strong>Year Of Curation: </strong>2014</p> <p><strong>Description: </strong>This research project involves forced vibration testing of the Four Seasons office building using the nees@UCLA equipment as well as detailed system identification and numerical modeling studies. Both earthquake-type and harmonic force histories were applied to the building at the roof level, and waveforms were recorded to enable evaluations of the complete structural system response, structural component behavior (e.g. slab-column connections and pile caps), and the response of non-structural components (e.g. piping systems) as well as the influence of these components on the system response. A dense instrumentation array including accelerometers, displacement transducers, and strain gauges was deployed. A wireless local area network was installed to acquire and record waveform data remotely from the mobile command center in real-time. The detailed data set generated from the tests provide valuable insights into the performance of this common type of structural system and the reasons for the poor performance of the subject building during the Northridge earthquake.

**标题**：四层钢筋混凝土（Reinforced Concrete，RC）建筑现场振动测试与分析研究（NEES-2014-1074）
**馆藏年份**：2014
**研究概述**：本研究项目依托NEES@UCLA设备对四季办公楼开展强制振动测试，并辅以精细化系统识别与数值模拟分析研究。研究团队在建筑屋顶施加地震动类与简谐力荷载历程，并记录振动波形，以全面评估整体结构系统响应、结构构件（如板柱节点与桩承台）性能、非结构构件（如管道系统）响应，以及此类构件对系统整体响应的影响。本次测试布设了包含加速度计、位移传感器与应变片在内的高密度测点阵列；搭建了无线局域网，可从移动指挥中心远程实时获取并记录波形数据。本次测试生成的精细化数据集，可为这类常见结构体系的性能表现，以及该受试建筑在北岭地震中性能不佳的原因提供极具价值的研究视角。
