For　concentrically　braced　frames　(CBFs)　with　conventional　braces,　although　they　can　prevent　collapse　during　earthquakes,　people　have　to　confront　the　costly　repair　work　and　long　downtime　induced　business　interruption,　which　is　often　attributed　to　excessive　residual　deformations.　Shape　memory　alloys　(SMAs)　provide　promising　solutions　to　this　problem.　SMAs　are　gaining　increasing　favor　by　the　community,　owing　to　their　excellent　superelasticity　which　endows　them　with　capabilities　of　recovering　large　deformation　and　dissipating　input　energy.　Currently,　the　authors　analyzed　the　seismic　performance　of　CBFs　with　a　novel　brace　termed　recentering　energy　dissipative　brace　(REDB).　The　REDB　is　essentially　a　parallel　combination　of　SMA　bars　and　steel　bending　plates,　the　former　primarily　provides　self-centering　capability　and　the　later　is　to　enhance　damping.　This　paper　is　to　understand　the　seismic　behavior　of　CBFs　braced　with　REDBs,　with　an　additional　motivation　to　examine　whether　the　REDBs　can　outperform　the　corresponding　buckling-restrained　braces　(BRBs).　Nonlinear　static　and　time-history　analyses　are　conducted　for　a　prototype　6-story　frame　building.　The　corresponding　results　are　compared　against　similar　BRB　frame.　The　basic　comparison　is　made　under　the　seismic　scenarios　associated　with　the　design-basis　earthquake　hazard　level.　Through　the　comparative　analysis,　it　is　found　that　the　properly　designed　REDBs　are　superior　to　the　BRBs　from　the　perspectives　of　generating　identical　demands　in　terms　of　maximum　interstory　drift　ratios　and　maximum　floor　accelerations,　and　meanwhile　eliminating　residual　interstory　drift　ratios.　The　confidence　of　the　results　is　further　gained　by　varying　the　seismic　intensity　and　the　assumed　damping　level.　(C)　2019　Elsevier　Ltd.　All　rights　reserved.
