Steel anti-buckling angle brace with high-strength energy absorption function

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
