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.
