Seismic fragility analysis of structure is fundamental in performance-based seismic design. The ground motion record set used in the analysis may have a characteristic effect on the fragility curves of a subway station structure. In this paper, fragility data have been developed by conducting the incremental dynamic analysis of subway station structure subjected to far-field record set (FFRS), near-field record set (NFRS), and near-filed record set with a pulse (NFRS + P). The dynamic analysis was conducted employing 2-D finite element models that account for soil nonlinearity and structural plastic damage. The vulnerability curves were derived utilizing the inter-story drift ratio as the damage measure (DM) and the peaks of ground acceleration as the intensity measure (IM). The results show that the second story was more prone to damage than the first story. The fragility curves derived from the data of the second story exhibited widely varying features for three ground motion record sets. The subway station sustained higher damage conditional probability when subjected to NFRS compared to NFRS + P and FFRS ground motions. The difference in the free field response under the three ground motion records sets directly correlates to the difference in the structural seismic vulnerability analysis. These results add to the rapidly expanding field of subway station performance-based seismic design.

结构的抗震性分析是基于性能的抗震设计的基础。分析中使用的地面运动记录集可能会对地铁车站结构的脆性曲线产生特征性影响。本文通过对地铁车站结构进行远场记录集（FFRS），近场记录集（NFRS）和带脉冲近场记录集（NFRS）的增量动力分析来开发脆弱性数据+ P）。使用二维有限元模型进行动力学分析，该模型考虑了土壤非线性和结构塑性损伤。利用层间漂移率作为破坏度量（DM），将地面加速度的峰值作为强度度量（IM）得出脆弱性曲线。结果表明，第二个故事比第一个故事更容易受到破坏。从第二个故事的数据得出的脆性曲线对于三个地面运动记录集表现出很大的差异。与NFRS + P和FFRS地面运动相比，受到NFRS影响的地铁站遭受破坏的条件概率更高。三个地面运动记录集下自由场响应的差异与结构地震易损性分析的差异直接相关。这些结果为地铁车站基于性能的抗震设计领域迅速发展提供了条件。与NFRS + P和FFRS地面运动相比，受到NFRS影响的地铁站遭受破坏的条件概率更高。三个地面运动记录集下自由场响应的差异与结构地震易损性分析的差异直接相关。这些结果为地铁车站基于性能的抗震设计领域迅速发展提供了条件。与NFRS + P和FFRS地面运动相比，受到NFRS影响的地铁站遭受破坏的条件概率更高。三个地面运动记录集下自由场响应的差异与结构地震易损性分析的差异直接相关。这些结果为地铁车站基于性能的抗震设计领域迅速发展提供了条件。
