A　new　kind　of　self-centering　and　free-repair　brace　with　friction　dampers　was　put　forward,　in　which　the　self-centering　and　the　energy　dissipating　capacity　were　provided　by　the　prestressed　steel　strand　and　the　friction　dampers　respectively.　In　the　work,　the　specimens　were　scaled　to　0.6.　Low　cyclic　loading　tests　with　two　designed　friction　conditions　have　been　conducted　to　investigate　the　deformation　performance,　hysteretic　characteristics,　energy-dissipated　capacity,　plastic　development,　post-tensioned　force　variation　and　self-centering　capacity.　Simultaneously,　numerical　simulation　has　been　carried　out　by　adopting　software　ABAQUS　and　compared　with　that　from　the　test.　The　results　indicate　that　the　new-type　brace　can　be　installed　feasibly　and　fleetly,　as　well　as　possessing　favorable　energy　dissipating　and　self-centering　capacity.　All　parts　of　the　brace　can　maintain　elastic　during　the　loading　process.　The　residual　deformation　is　very　small　in　later　period　of　the　loading　process.　Stiffness　of　the　brace　remains　relatively　large.　The　installation　of　the　brass　sheets　in　friction　dampers　can　avoid　the　maturing　condition　of　friction　interfaces　as　well　as　providing　stable　energy　friction　capacity.　Reduction　of　the　cable　forces　in　braces　is　very　small　after　the　loading　process.　Therefore,　the　braces　can　continue　to　work,　achieving　the　design　target　of　＇self-centering　and　free-repair＇,　as　well　as　reducing　the　repairing　cost　of　the　architecture.　©　2018,　Editorial　Office　of　Journal　of　Vibration　and　Shock.　All　right　reserved.
