Buckling-restrained steel frame beam column connecting structure

Abstract

The invention discloses a buckling-restrained steel frame beam column connecting structure, and belongs to the technical field of building structures. The structure comprises an I-shaped steel column, an I-shaped steel beam and a buckling-restrained connecting part; the I-shaped steel column and the I-shaped steel beam are connected through the buckling-restrained connecting part; the buckling-restrained connecting part comprises buckling-restrained channel steel, side buckling-restrained channel steel and an energy dissipater; arc-shaped groove openings are formed in the side edges of an upper flange plate and a lower flange plate of energy dissipater I-shaped steel respectively; the buckling-restrained channel steel is arranged on the upper side and the lower side of the energy dissipater I-shaped steel respectively; the buckling-restrained channel steel is arranged on the two sides of a middle web of the energy dissipater I-shaped steel respectively; and arc-shaped base plates matched with the arc-shaped groove openings are arranged at the arc-shaped groove openings. According to the buckling-restrained steel frame beam column connecting structure, lateral instability of a steel beam is avoided, the seismic energy dissipation property of a joint is improved, and the seismic capacity is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of building structures, in particular to a buckling-resistant steel frame beam-column connection structure. Background technique [0002] In the design of high-rise buildings, the joints connected by beams and columns are the key points in the design of structural joints of high-rise buildings. Their performance directly affects the strength, stiffness, and stability of the structure. In the past, there have been many studies on the weakening of beams, but Often buckling occurs. [0003] In the traditional joint design, the full penetration butt weld is often used, which does not give full play to the advantages of the beam-column joint and the bending capacity of the beam itself, and does not make good use of the "strong joint weak joint" in the seismic design. Components” design principles. Contents of the invention [0004] Based on the above technical problems, the present invention proposes a buckli...
