Anti-seismic component and buffer with dual functions of energy consumption and bearing capacity

Abstract

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.
