Based　on　the　concept　of　structural　fuses　and　the　target　of　reducing　residual　displacement,　the　design　concept　of　self-centering　energy　dissipation　brace　(SCEB)　applied　in　the　structural　fuse　for　double-column　bridge　structure　was　proposed.　Firstly,　a　novel　SCEB-self-centering　buckling　restrained　brace　was　proposed.　The　working　mechanism　was　clarified　and　the　mechanical　behavior　of　the　SCEB　was　experimentally　verified.　The　restoring　force　model　of　double-column　bridge　piers　with　SCEB　was　then　established　based　on　the　mechanical　performance　of　the　SECB,　and　the　design　method　of　the　SCEB　for　double-column　bridge　pier　was　proposed.　The　damage　of　the　column　could　be　reduced　and　the　residual　displacement　of　the　structure　could　be　effectively　controlled,　with　the　reasonable　design　of　the　SCEB　for　yielding　and　dissipating　energy　before　the　column.　Numerical　analyses　on　seismic　performance　of　the　pier　with　the　SCEB　were　carried　out　by　OpenSees　FE　platform　to　assess　the　viability　and　the　availability.　The　results　show　that　the　proposed　SCEB　exhibits　good　self-centering　abilities　and　moderate　energy　dissipation　capability,　and　force-displacement　hysteretic　curves　present　the　flag-shaped　characteristic.　Numerical　simulations　manifest　that　the　seismic　performance　and　energy　dissipation　capacity　of　bridge　with　the　fuse　element　are　better　than　those　of　the　cross　link　beam　structure,　and　SCEB　used　in　double-column　piers　is　effective.　In　particular,　the　SCEB,　compared　with　BRB,　can　enhance　the　lateral　stiffness,　the　protective　action　and　energy　dissipation　capacity　of　bridge　columns　to　mitigate　the　seismic　damage　of　columns.　The　residual　displacement　of　columns　can　be　effectively　reduced　and　eliminated　by　SCEB.　©　2017,　Editorial　Department　of　China　Journal　of　Highway　and　Transport.　All　right　reserved.
