Lingzhao　Xuan,　located　in　the　Palace　Museum,　has　significant　historical,　artistic　and　scientific　values.　To　investigate　the　safety　status　and　seismic　performance　of　the　Lingzhao　Xuan　structure,　the　material　composition　and　performance　of　the　main　load-bearing　members　of　the　Lingzhao　Xuan　were　examined,　and　a　finite　element　seismic　simulation　was　performed　on　the　model.　The　results　show　that　under　different　seismic　intensities,　the　deformation　of　the　central　pavilion　is　more　evident　than　that　of　the　four　metal　pavilions　in　the　corner.　Under　the　8-degree　frequent　seismic　intensities,　the　tensile　stress　in　the　local　area　of　the　masonry　has　exceeded　the　design　tensile　strength　value　of　the　masonry,　posing　a　risk　of　structural　cracking.　Under　the　8-degree　rare　seismic　intensity,　when　the　seismic　waves　are　along　the　direction　of　the　east-west　engineering　axis,　the　stress　at　the　column　foot　of　the　central　pavilion　is　greater　than　the　tensile　strength　of　the　cast　iron.　When　the　seismic　waves　are　along　the　direction　of　the　south-north　engineering　axis,　the　stress　of　the　tie　beam　in　the　north-south　direction　of　the　central　pavilion　exceeds　the　tensile　strength　of　the　cast　iron.　The　structure　has　a　greater　risk　of　collapse　due　to　excessive　deformation.
