Three　buckling-restrained　brace　concrete　frames　(BRBCF)　with　different　BRB　or　beam　sections,　which　were　normal　reinforced　concrete　beam　with　monoclinic　BRB,　flat　beam　with　monoclinic　BRB,　normal　reinforced　concrete　beam　with　invert-V　BRB,　were　designed,　manufactured　and　tested　by　quasi-static　test.　The　seismic　performance,　including　cracks　on　concrete　elements,　lateral　load-displacement　loops,　skeleton　curves,　tangent　stiffness　and　its　degradation,　and　BRB　load-deformation　curves,　were　studied.　Test　results　show　that　the　BRB　and　concrete　frame　can　effectively　work　together　to　resist　lateral　force.　The　system　has　plump　and　stable　hysteric　load-displacement　curves.　The　BRB　can　start　to　dissipate　energy　by　yielding　at　relatively　small　story　drift　ratio,　and　avoid　failure　at　large　lateral　drift　ratio.　It　is　validated　that　the　equivalent　viscous　damping　can　thus　be　increased　and　the　seismic　response　be　reduced,　resulting　in　an　improved　structural　performance.　The　designed　concrete　joints,　the　embedded　parts　and　the　connectors　function　well　and　reliably.
