To　effectively　protect　Tai-he　Palace　in　the　Forbidden　City　in　China,　its　aseismic　behaviors　were　studied　by　finite　element　analysis.　Based　on　typical　constitutions　of　Tai-he　Palace,　its　finite　element　model　was　built.　By　modal　analysis,　its　basic　frequencies　as　well　as　main　modes　were　obtained;　by　response　spectrum　analysis,　its　bearing　performances　under　8　degree　intensity　of　frequently　occurred　earthquakes　were　studied;　by　time　history　analysis,　its　displacement　and　acceleration　response　curves　under　8　degree　intensity　of　seldom　occurred　earthquakes　were　further　discussed.　Results　show　that　basic　frequency　value　of　Tai-he　Palace　is　0.85Hz;　its　main　modes　are　of　translation,　which　have　little　relation　between　each　other　in　level　directions.　Both　its　internal　forces　under　8　degree　intensity　of　frequently　occurred　earthquake　and　its　peak　deformation　under　8　degree　intensity　of　seldom　occurred　earthquakes　are　within　the　permission　scopes,　reflecting　its　good　aseismic　performances.　Besides,　its　constitutions　such　as　tenon-mortise　joints,　tou-kung　(bracket　sets),　free-standing　column　roots　and　so　on　are　helpful　for　seismic　response　mitigation.
