对加速度敏感的非结构元件不仅构成建筑物组件库存的重要组成部分，而且还包括对于基本设施的连续运行必不可少的组件和系统。在新西兰，地震荷载标准 NZS 1170.5：地震作用的第 08 节和专用标准 NZS 4219：建筑物工程系统的抗震性能解决了非结构构件的抗震设计问题。本文仔细研究了 NZS 1170.5 和 NZS 4219 中对加速度敏感的非结构元件的设计规定，并通过与 ASCE 7-16、最新 ATC 方法和欧洲规范 8 中规定的非结构元件的设计规定进行比较，提供了国际视角。随后详细讨论了元件需求估计所需的改进、与性能目标一致的设计标准的必要性、现实延展性因素的定义以及对未来的前进方向是改进设计程序及其通过新的抗震评级框架的应用。
Acceleration-sensitive non-structural elements not only constitute a significant portion of a building’s component inventory, but also comprise components and systems that are indispensable to the operational continuity of essential facilities. In New Zealand, Section 08 of the seismic loadings standard, NZS 1170.5: Earthquake Actions, and a dedicated standard, NZS 4219: Seismic Performance of Engineering Systems in Buildings, address the seismic design of non-structural elements. This paper scrutinizes the design provisions for acceleration-sensitive non-structural elements in NZS 1170.5 and NZS 4219, and provides an international perspective by comparing with the design provisions for non-structural elements specified in ASCE 7-16, the latest ATC approach and Eurocode 8. This is followed by a detailed discussion on the improvements required for component demand estimation, the need for design criteria that are consistent with performance objectives, definition of realistic ductility factors, and recommendations for the future way forward in the form of an improved design procedure and its application through a new seismic rating framework.
