To　protect　Chinese　ancient　buildings,　aseismic　behaviors　of　wooden　structure　strengthened　by　iron-hook　are　studied　through　experiments.　Based　on　actual　sizes　of　the　3rd　frame　of　Tai-He　Palace　in　the　Forbidden　City,　three　wooden　frame　models　with　a　scale　of　1:8　of　the　prototype　structure　were　built　considering　tenon-mortise　connections.　Low　cyclic　reversed　loading　tests　were　carried　out　by　manual　loading　means　and　means　of　load-displacement　hysteretic　curves　and　skeleton　curves　of　the　structures　were　obtained.　By　analyzing　their　energy　dissipation　capability,　stiffiness　degradation　and　deformation　performance　were　studied.　Results　show　that　after　the　structure　is　being　strengthened　by　iron-hooks　and　with　their　embedding　effects,　tenon　pulled　out　of　the　mortise　becomes　less,　stiffness　and　strength　of　the　structure　are　enhanced,　stiffness　degradation　of　the　structure　is　not　obvious,　and　its　deformation　performance　is　still　good,　however　its　energy　dissipation　capability　decreases.
