NEESR-CR: Full-Scale Structural and Nonstructural Building System Performance During Earthquakes

该奖项是NSF 09-524项目招标“小乔治·e·布朗地震工程模拟（NEES）研究网络（NEESR）”竞赛的结果，包括加州大学圣地亚哥分校（牵头机构）、圣地亚哥州立大学（次级奖项）和霍华德大学（次级奖项）。该项目将利用加州大学圣地亚哥分校（UCSD）和加州大学洛杉矶分校（UCLA）的NEES设备站点。其他核心项目团队成员包括领导代码开发活动的行业成员和伍斯特理工学院的研究人员。智力优势：非结构部件和系统（NCS）是建筑物内不参与建筑物承重系统的那些元素。ncs通常分为建筑、机械、管道或内容项目或项目系统。自19世纪以来，ncs已经证明了它们在地震期间为建筑物居住者创造危险环境的潜力。由于这些因素通常占建筑物总投资的80%以上，因此即使是轻微的损坏也可能导致重大的经济损失。事实上，在过去的三十年里，大多数地震引起的建筑物直接损失都直接归因于NCS的破坏。在美国进行的为数不多的全面建筑实验中，没有一个专门关注于评估非结构部件和系统（NCSs）在地震中的反应。该项目涉及一个具有里程碑意义的测试，一个完整的五层建筑配备了ncs，包括一个功能性的乘客电梯、隔墙、包层和玻璃系统、管道、暖通空调、天花板、洒水装置和其他建筑内容，以及被动和主动消防系统。NEES-UCSD和NEES-UCLA的设备结合起来实现了这一独特的机会，从而促进了对复杂结构和非结构部件和系统的全尺寸动态响应和运动学相互作用的理解。虽然这些实验中的大多数ncs将按照最先进的建筑规范抗震规定进行设计，但在美国低地震地区广泛使用的非地震详细设计也将包括在内。此外，本研究将探讨使用阻尼和/或隔离方法保护关键NCS系统的潜力。来自这些独特实验的数据将用于比较使用现有商业和研究计算建模平台确定的地震性能预测。在系统层面上整合结构和NCSs并解决诸如系统组件之间有害的运动学和动态交互等问题的研究是缺乏的。这项研究将首次使复杂系统的测试成为可能，该系统密切关注多学科问题，使用设备齐全的设施，在受控环境中调查地震对建筑ncs系统性能的影响。更广泛的影响：本研究的结果将对NCS的基于性能的设计产生广泛而直接的影响，包括NCS消防系统。本研究将支持地震工程领域的博士生和建筑管理与防护系统领域的硕士生。该项目建立了独特的合作伙伴关系，通过教育活动吸引了来自霍华德大学的教师和学生，以及来自建筑技术学院（圣地亚哥的工程和建筑磁铁项目）的高中生，吸引了不同的学生群体参与地震工程。这项研究的数据将存档，并通过NEES数据储存库向公众提供。

This award is an outcome of the NSF 09-524 program solicitation "George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) Research (NEESR)" competition and includes the University of California, San Diego (lead institution), San Diego State University (subaward), and Howard University (subaward). This project will utilize the NEES equipment sites at the University of California, San Diego (UCSD) and the University of California, Los Angeles (UCLA). Additional core project team members include industry members leading code development activities and researchers at Worcester Polytechnic Institute. Intellectual Merit: Nonstructural components and systems (NCS) are those elements within a building that do not contribute to the building's load bearing system. NCSs are generally categorized as being either an architectural, mechanical, plumbing, or content item or system of items. Since the 19th century, NCSs have demonstrated their potential to create a dangerous environment for building occupants during earthquake shaking. Since these elements generally represent more than 80% of the total investment of a building, even minor damage can translate to significant financial losses. In fact, over the past three decades, the majority of earthquake-induced direct losses in buildings are directly attributed to NCS damage. Of the handful of full-scale building experiments conducted in the United States, none have specifically focused on evaluating the response of nonstructural component and systems (NCSs) during earthquake shaking. This project involves a landmark test of a full-scale, five-story building completely furnished with NCSs, including a functioning passenger elevator, partition walls, cladding and glazing systems, piping, HVAC, ceiling, sprinklers, and other building contents, as well as passive and active fire systems. The NEES-UCSD and NEES-UCLA equipment combine to realize this unique opportunity and hence advance understanding of the full-scale dynamic response and kinematic interaction of complex structural and nonstructural components and systems. While most NCSs in these experiments will be designed to the latest state of the art building code seismic provisions, non-seismic detailed designs widely used in low-seismic regions of the United States will also be included. Furthermore, this research will investigate the potential for protecting critical NCS systems using, for example, damping and/or isolation methods. Data from these unique experiments will be used to compare earthquake performance predictions determined using available commercial and research computational modeling platforms. Research at the system level that incorporates the structure and the NCSs and addresses issues such as detrimental kinematic and dynamic interaction between systems components is lacking. This research will enable, for the first time, tests of complex systems, which look closely at multidisciplinary issues, using facilities that are fully equipped to investigate, in a controlled environment, the effects of earthquakes on building-NCS system performance. Broader Impacts: Outcomes from this research will have broad and immediate impacts on the performance-based design of NCSs, including NCS fire protection systems. This research will support doctoral students in the earthquake engineering area and master students in construction management and protective systems areas. The project has developed unique partnerships to attract a diverse student group to earthquake engineering via educational activities that engage faculty and students from Howard University, as well as high school students from the Construction Tech Academy (an engineering and construction magnet program in San Diego). Data from this research will be archived and made available to the public through the NEES data repository.
