This　study　developed　a　special　energy　dissipation　X-bracing　for　cold-formed　steel　(CFS)　shear　walls　to　improve　the　ductility　of　the　corrugated　steel　sheathing.　In　previous　research,　CFS　shear　walls　with　corrugated　sheathing　demonstrated　poor　ductility　under　cyclic　loading.　The　paper　presents　a　potential　solution　by　adding　a　special　energy　dissipation　bracing　(EDB)　to　improve　the　ductility　of　the　corrugated　sheet-sheathed　shear　walls.　The　EDB　can　be　tuned　according　to　the　CFS　shear　wall　base　performance　to　achieve　the　highest　postpeak　deflection　capacity,　thereby　significantly　improving　the　seismic　ductility.　To　prove　the　concept　and　analyze　the　feasibility　of　the　new　EDB,　a　test　program　of　nine　full-scale　shear　walls　was　conducted.　The　experimental　results　showed　that　with　the　tuned　EDB,　the　corrugated　steel　sheet-sheathed　shear　walls　had　improved　ductility　with　no　considerable　reduction　in　the　initial　stiffness　and　shear　strength.　Installing　the　proposed　EDB　can　be　an　efficient　approach　to　enhance　the　seismic　performance　of　CFS-framed　shear　walls.　Details　of　the　test　program　and　discussion　are　presented.
