Abstract
En 中文
The ability to quantify the seismic risk associated with structural and non-structural elements is a critical aspect of earthquake engineering. While methods to improve the understanding of structural response to earthquake shaking and how to quantify their risk have been studied, non-structural elements (NSEs) have more recently emerged as a crucial aspect to address given their pertinence in overall building performance and loss-related issues. This article describes the development of a risk quantification methodology for NSEs whereby the mean annual frequency of exceeding an NSE's damage state is computed and rated as part of a risk classification scheme using recently developed approaches. The basis of the methodology is described in detail followed by an example implementation, where the details surrounding hazard, structural and non-structural response are quantified consistently, ensuring that uncertainties are also incorporated to be in line with modern performance-based earthquake engineering. Discussion is provided surrounding the potential future use of such an NSE risk classification scheme for both structural engineers looking to improve the performance of their buildings via NSE performance and also manufacturers.
