NEESR-SG: Experimental Determination of Performance of Drift-Sensitive Nonstructural Systems under Seismic Loading

摘要：。该项目解决了地震工程界在提供包括立面、管道和楼梯在内的非结构建筑构件系统的力-位移关系的量化值方面的关键需求。从该项目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。还将使用现有的商业软件来改进计算机建模工具，以模拟这些系统对地震激励的反应。将评估在实验组件上使用损伤传感器系统的情况，以促进结构健康监测。非结构部件的性能将包括一个案例研究，即为重复使用和回收材料而对部件进行解构。通过对一个原型九层钢框架结构建筑的维修费用分析，建立了非结构构件的破坏费用与建筑物在地震中的峰位漂移之间的关系。网络基础设施组件将允许实践设计工程师通过用户友好的界面将NEES存储库测试数据直接合并到他们的工程计算中。这个与资料库的新链接将允许设计专业人员在新建筑的设计和对现有建筑的评估中使用最新的工程研究。开发的工作将是地震工程界以外的宝贵知识。在许多类型的极限荷载中，非结构构件的性能是至关重要的。早期职业专业人员、妇女和代表性不足的少数群体将参与许多方面的研究，并将为K-12教育开发信息。

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.
