Abstract: . This project addresses critical needs for the earthquake engineering community in providing quantified values for the force-displacement relationships of non-structural building components systems including facades, plumbing and stairways. The data obtained from the project will allow building engineers to model performance of these systems in both existing and future building designs. Improved computer modeling tools will also be produced in the use of existing commercial software to simulate the response of these systems to seismic excitation. The use of damage-sensor systems on experimental assemblies will be evaluated with the goal of advancing structural health monitoring. Included in the performance of non-structural components will be a case study of the deconstruction of the components for both re-use and recycling of materials. A repair cost analysis of a prototype nine-story steel frame building will be made to develop a relationship between damage cost of non-structural components and peak drift a building experiences during an earthquake. A cyberinfrastructure component will allow practicing design engineers to incorporate NEES Repository test data directly into their engineering calculations with a user-friendly interface. This new link to the repository will allow design professionals to use the latest in engineering research in the design of new buildings and the evaluation of existing ones. The work developed will be valuable knowledge beyond the world of earthquake engineering. Performance of non-structural elements is critical in many types of extreme loading. Early career professionals, women and underrepresented minorities will be engaged in many aspects of the research and information for K-12 education will be developed.

摘要：.该项目解决了地震工程界的关键需求，为非结构建筑部件系统（包括立面，管道和楼梯）的力-位移关系提供量化值。从该项目中获得的数据将使建筑工程师能够在现有和未来的建筑设计中模拟这些系统的性能。还将利用现有的商业软件制作改进的计算机模拟工具，以模拟这些系统对地震激励的反应。 损伤传感器系统的使用实验组件将进行评估，推进结构健康监测的目标。 在非结构性组件的性能将是一个案例研究的解构组件的再利用和回收材料。一个原型的九层钢框架建筑的维修成本分析将开发的非结构部件的损坏成本和峰值漂移的建筑物在地震期间的经验之间的关系。 一个网络基础设施组件将允许实践设计工程师将NEES存储库测试数据直接纳入其工程计算中，并提供用户友好的界面。这个与知识库的新链接将使设计专业人员能够在新建筑的设计和现有建筑的评估中使用最新的工程研究。 这项工作的发展将是超越地震工程世界的宝贵知识。 非结构元件的性能在许多类型的极端载荷中至关重要。 早期职业专业人士，妇女和代表性不足的少数民族将参与研究的许多方面，并将开发K-12教育信息。
