Due　to　a　lack　of　seismic　design,　traditional　timber　structures　make　their　mortise　and　tenon　joints　susceptible　to　seismic　action.　To　date,　there　are　limited　mortise　and　tenon　joints　strengthening　techniques　that　are　efficient　and　safe.　This　study　proposed　a　novel　assembled　hoop　of　adjustable　stiffness　to　enhance　the　seismic　resilience　of　joints.　To　evaluate　the　efficacy　of　this　reinforcing　technique,　two　1/2　scaled　Chuan-dou　timber　structural　models　were　designed,　namely　intact　and　reinforced　models.　The　comparative　analysis　of　these　models　was　conducted　by　shaking　table　tests.　Under　a　seismic　intensity　of　8.0,　the　dynamic　amplification　factor　of　the　reinforced　model　decreased　by　2.9　%　compared　to　the　intact　model,　and　the　maximum　displacement　response　decreased　by　27　%.　This　indicates　that　the　seismic　performance　of　the　reinforced　structure　was　restored　to　the　same　level　as　the　intact　structure.　Additionally,　the　interstory　drift　was　reduced　from　1/33–1/35.　This　indicates　that　the　proposed　reinforcement　technique　is　feasible　and　effective　in　the　seismic　performance　and　local　joints　energy　dissipation　for　the　Chuan-dou　timber　structure.　©　2025　Institution　of　Structural　Engineers
