To　protect　Chinese　ancient　buildings,　the　aseismic　behaviors　of　ancient　Chinese　wooden　structures　strengthened　by　different　methods　on　the　tenon　and　mortise　joints　were　studied　through　experiments.　Based　on　actual　sizes　of　an　ancient　building　in　the　Forbidden　City,　wooden-frame　models　with　scale　of　1:　8　of　the　prototype　structure　were　built,　incorporating　Yan-wei　(dovetail)-type　tenon　and　mortise　joints.　By　manual　loading,　low　cyclic　reversed　loading　tests　were　carried　out　to　study　the　aseismic　behaviors　of　the　models　after　their　tenon　and　mortise　joints　are　separately　strengthened　by　an　iron　hook,　carbon　fiber-reinforced　plastic　(CFRP)　sheets,　and　steel　components.　Nine　tests　were　conducted,　including　three　tests　for　unstrengthened　models　and　two　tests　for　each　of　the　three　strengthening　methods　mentioned　above.　Through　experimentation,　load-displacement　hysteretic　curves　and　skeleton　curves　of　the　models　are　obtained.　Their　energy　dissipation　capability,　stiffness　degradation,　and　deformation　performance　are　studied　through　analysis.　The　application　range　of　each　method　is　also　discussed.　Results　show　that　the　wooden　models　have　good　deformation　performance　both　before　and　after　the　tenon　and　mortise　joints　were　strengthened.　The　performance　of　the　strengthening　methods　depended　on　the　property　of　interest:　CFRP　sheets　＞　steel　components　＞　iron　hook　in　load　bearing　capability　of　the　model;　iron　hook　＞　steel　components＞　CFRP　sheets　in　energy　dissipation　capability　of　the　model;　and　CFRP　sheets　＞　iron　hook　＞　steel　components　in　stiffness　degradation　of　the　model.　Thus,　the　engineering　application　suggestions　for　different　strengthening　methods　are　as　follows:　iron　hooks　for　small　wooden　structures,　CFRP　sheets　for　medium-and　small-sized　wooden　structures,　and　steel　components　for　medium-and　large-sized　wooden　structures.
