A　traditional　Pall　friction　damping　brace　system　is　improved　by　a　Pall-typed　frictional　damper-shape　memory　alloy(PFD-SMA)　brace　system,　which　makes　full　use　of　PFD　and　the　advantages　of　SMA.　The　system　has　the　energy　dissipation　ability　and　self-resetting　function.　The　influences　of　SMA＇s　stiffness,　slip　force　of　the　Pall-typed　damper,　maximum　recovery　strain,　elasticity　modulus,　and　length　of　SMA　brace　are　analyzed.　Results　show　that　the　PFD-SMA　frictional　brace　system　has　the　same　energy　dissipation　with　an　origin　Pall　brace　system,　even　in　the　case　of　hugging　SMA　brace　can　consume　energy　by　itself.　The　system　has　a　dual　self-resetting　function　by　SMA＇s　super-elastic　performance　and　shape　memory　effect.
