Seismic design and evaluation of non-structural building components

非结构组件（NSC）包括建筑组件，建筑设备和建筑内容，占建筑物总建筑成本的75-85%。在最近的强震中，典型的破坏报告显示，即使在性能良好的建筑物中，神经干细胞的破坏也会造成严重的经济损失。对于医院、应急管理中心、供水和水处理设施等关键设施而言，功能丧失或中断可能尤为重要。加拿大国家建筑规范（NBCC）的理念是在不解决其脆弱性的情况下寻求NSC的生存。它假设NSC和建筑物的行为是解耦的，并提供经验方程来估计NSC的峰值水平地板加速度需求。NSC的峰值垂直地板加速度需求尚未解决。*该计划的长期目标是建立一个国际公认的研究计划，研究典型的NSC对建筑物抗震性能的贡献。在基于性能的地震工程框架内，NSC的增强抗震性能如今被广泛认为是控制经济损失和停机时间以及生命安全的关键因素。作为实现这一目标的一步，这项为期5年的研究计划将侧重于通过应用NBCC当前版本中可用的经验公式来提高地震目标性能水平。在加拿大地震灾害背景下，将通过合理确定其地震需求（峰值水平和垂直地板加速度和频谱）来评估“加速度敏感”NSC对地震的脆弱性。然后，通过将NSC集成到建筑物的结构分析中并提出简化的建模技术来研究NSC与建筑物结构的相互作用。最后，该计划将帮助支持五名研究生。

Non-Structural Components (NSCs) which include architectural components, building services and building content, account for 75-85% of the total construction cost in buildings. Typical damage reported in recent strong earthquakes reveals the heavy economic losses arising from damage to NSCs even in buildings that perform well. Loss or disruption of functionality can be particularly important in the case of critical facilities such as hospitals, emergency management centers, water supply and water treatment facilities. The National Building Code of Canada (NBCC) philosophy seeks the survival of NSCs without addressing their vulnerability. It assumes that the behavior of NSCs and the building are decoupled and provides empirical equations to estimate peak horizontal floor acceleration demand on NSCs. The peak vertical floor acceleration demand on NSCs is not addressed yet.*******The long-term objective of this program is to build an internationally-recognized research program studying the contribution of typical NSCs to the seismic performance of buildings. In the framework of the Performance-Based Earthquake Engineering, the enhanced seismic performance of NSCs is nowadays widely recognized to be a key factor in order to control economic losses and downtime in addition to life safety.*******As a step towards this goal, this 5-year research program will focus on enhancing the seismic target performance levels achieved by applying the empirical equations available in the current editions of the NBCC. In a Canadian seismic hazard context, the vulnerability of «acceleration-sensitive» NSCs to earthquakes will be assessed by determining rationally their seismic demand in terms of peak horizontal and vertical floor accelerations and spectra. Then, the interaction of NSCs with the building structure will be investigated by integrating NSCs into the structural analysis of the building and proposing simplified modeling techniques.*******Finally, this program will help to support five graduate students.******
