A　new　type　of　BRB　(buckling-restrained　braces)　is　designed　and　tested.　With　both　ends　strengthened,　the　braces　are　made　of　hot-rolled　steel　angle　core.　It　has　an　advantage　of　simple　and　effective　for　manufacturing　with　low　price.　Seven　specimens　were　tested,　including　four　BRAB　(buckling-restrained　angle　brace)　with　two　cross　section　types　(quasi-cross　and　T　section)　at　combination　methods　(welded　or　without　welding),　three　BRB　made　of　hot-rolled　steel　plate　for　comparison.　Cyclically　static　loading　tests　were　conducted.　Seismic　behaviors,　such　as　force-deformation　hysteresis　loops,　accumulated　plastic　deformation,　and　tangent　stiffness　and　its　deterioration,　as　well　as　equivalent　damping　ratio　are　studied.　It　is　validated　that　the　new　BRB　using　angle　core　has　a　reliable　performance　with　high　energy　dissipation　property　and　can　be　used　to　satisfy　design　requirements　for　buildings　in　seismic　region.
