Abstract

The invention discloses a steel anti-buckling angle brace with a high-strength energy absorption function. The steel anti-buckling angle brace comprises a steel frame beam, columns, an anti-buckling angle brace body and an energy dissipation coupling beam, wherein the beam is connected with the columns through bolts, the energy dissipation coupling beam is connected between the columns through bolts, the anti-buckling angle brace body is connected in an area near a beam-column joint through bolts, and meanwhile, stiffening ribs are additionally arranged at webs at corresponding positions of the beam and the columns. An anti-seismic component can play a bearing role in a normal use state, the integrity of a building structure is enhanced, and elasticity is kept; under the action of an earthquake, the functions are played in stages, the energy dissipation coupling beam absorbs earthquake energy through plastic deformation all the time, the anti-buckling angle brace body deforms to different degrees under small, medium and large earthquakes, the earthquake energy is absorbed, and the influence of the earthquakes on a house structure is reduced; and under a huge earthquake, the angle brace body is fully deformed to dissipate energy, the impact energy of the earthquake action on key parts of a building is fully consumed, the anti-seismic performance of a used house is improved, and the advantage of rapid assembly is achieved.

Description

technical field [0001] The invention belongs to the field of earthquake prevention and disaster reduction in civil engineering, and is a new type of assembled steel structure with anti-buckling corner braces and energy-dissipating connecting beams. Maintain continuous energy consumption performance during the process. Background technique [0002] As an important issue in civil engineering research, building earthquake resistance has always received special attention from researchers. With the rapid development of urban economy and technology, ensuring social stability and economic development has become the focus of engineering attention, and the overall structural toughness has become the goal of the project. When disturbed by earthquakes, the mechanical characteristics of the engineering structure will change. The interference of the earthquake on the building structure will affect the storage of sensitive items inside the building and the lives of residents. Fragile ite...
