Disclosed in the present invention are an anti-seismic component with dual functions of energy consumption and load bearing, and a buffer. The anti-seismic component includes a core shaft, wherein the core shaft is connected to a first support member and a second support member; an overhanging section of the first support member and an overhanging section of the second support member are respectively arranged on two sides of the core shaft; and an included angle between the first support member and the second support member is less than 180°. The component can be directly used as an inclined brace component of a building frame structure, and uses a circular tube torsional energy consumption mode to replace an axial tension and compression energy consumption mode of a traditional BRB component, thereby eliminating the problem of compressive buckling of a support component and simplifying the structure of a steel structure energy-consumption inclined brace; and there is no need for an external restrain component, thereby reducing steel consumption, avoiding filling with mortar, effectively shortening an installation period, improving the reliability of the component, and greatly reducing the manufacturing cost of the component. Therefore, the component has wide application prospects.
A bumper, comprising two oppositely arranged anti-seismic members with dual functions of energy consumption and bearing, wherein each anti-seismic member comprises first and second mandrels, a first support (21) connected to the first mandrel, a second support (22) connected to the second mandrel, and a connector (5) connecting the first and second mandrels, the first support (21) includes a first cantilever section and the second support (22) includes a second cantilever section, the first cantilever section and the second cantilever section are on opposite sides of the first and second mandrels, the first support (21) and the second support (22) have an included angle therebetween that is less than 180°, the first support (21) of each anti-seismic member has a first cantilever end connected to the first cantilever end of the other anti-seismic member through a first connecting piece, the second support (22) of each anti-seismic member has a second cantilever end connected to the second cantilever end of the other anti-seismic member through a second connecting piece, the first cantilever ends of the first supports (21) and the second cantilever ends of the second supports (22) are rotatably connected with the corresponding first and second connecting pieces, and when relative positions of the first and second connecting pieces change, the first and second mandrels twist and deform to consume energy.
