In　order　to　well　protect　Chinese　ancient　buildings,　aseismic　behaviors　of　Chinese　ancient　tenon-mortise　joints　strengthened　by　carbon　fibre　reinforced　plastic　(CFRP)　are　studied　by　experiments.　Based　on　the　actual　size　of　an　ancient　building,　a　wooden　frame　model　with　a　scale　of　1:8　of　the　prototype　structure　is　built　considering　the　swallow-tail　type　of　tenon-mortise　connections.　Low　cyclic　reversed　loading　tests　are　carried　out　including　three　groups　of　unstrengthened　structures　and　two　groups　of　structures　strengthened　with　CFRP.　Based　on　experimental　data,　moment-rotation　angle　hysteretic　curves　and　skeleton　curves　for　each　joint　are　obtained.　The　energy　dissipation　capability,　stiffness　degradation　and　deformation　performance　of　the　joints　before　and　after　being　strengthened　are　also　analyzed.　Results　show　that　after　being　strengthened　with　CFRP,　the　tenon　value　pulled　out　of　the　mortise　is　reduced;　the　bending　strength　and　the　energy　dissipation　capabilities　of　the　joint　are　enhanced;　stiffness　degradation　of　the　joint　is　not　obvious;　and　the　deformation　performance　of　the　joint　remains　good.　Thus,　the　CFRP　has　good　effects　on　strengthening　the　tenon-mortise　joints　of　Chinese　ancient　buildings.　©　Copyright.
