Abstract:To enhance the resilience of metro stations against earthquake-induced secondary fires, a multidimensional quantitative assessment framework grounded in national standards is developed. By systematically deconstructing five national fire safety codes—including the Standard for Fire Protection Design of Metro (GB 51298-2018)—a comprehensive evaluation system comprising 9 dimensions and 22 indicators is established, thereby translating prescriptive code requirements into measurable resilience metrics. To address the inherent fuzziness and randomness in the assessment process, a forward cloud model is employed to enable robust conversion of qualitative concepts into quantitative values. The proposed approach is validated through a case study of Chengdu"s Xingfu Meilin Station—the largest column-free arched metro station in China—whose fire resilience is assessed as "high" .Results demonstrate that the framework effectively transcends the limitations of conventional compliance-based inspections, offering a scientific and practical tool for quantifying and enhancing fire resilience in metro stations under compound seismic–fire hazards.
