Problems solved by technology

However, the design of the existing pure steel buckling-restrained braces ignores an important problem, that is, the ability of the core element itself to resist local buckling is not utilized.
The reason for this phenomenon is that the section of the core unit, such as the "one"-shaped plate and "ten"-shaped combined section and the flange of the H-shaped steel, is a cantilevered part, which is prone to local buckling under the action of axial force, so The existing pure-steel buckling-restrained supports cannot utilize the ability of the core unit itself to resist local buckling, resulting in a decline in the overall economy

Embodiment Construction

[0022] Such as Figure 1-Figure 7 Shown: a pure steel box-shaped steel buckling restraint support, which includes a box-shaped steel 1 and a sleeve 5 sleeved outside the box-shaped steel; the box-shaped steel is a rectangular tube, in the middle of the four sides at its two ends Grooves are opened symmetrically, and cross-shaped stiffeners 2 are welded in the grooves; Figure 8 As shown: the cross-shaped stiffener is formed by vertically intersecting and welding two flat plates 7 with grooves. The four faces of the inner wall of the sleeve 5 are all symmetrically provided with channel steels 3, and every pair of channel steels is arranged with their backs facing each other, and their backs are pressed against each surface of the box-shaped section steel respectively.

[0023] Such as Figure 9 Shown: the pure steel box-shaped steel buckling-constrained support, its oblique support is arranged between the column 8 and the roof beam 9 .

[0024] The four faces that make up th...

Abstract

The invention relates to a clean steel box type profile steel buckling restrained brace which comprises box type profile steel and a sleeve sleeved outside the box type profile steel. The box type profile steel is a rectangular pipe. Grooves are symmetrically and respectively formed in the middles of the four edges at two ends of the rectangular pipe. A cross stiffening rib is welded into the each groove. Channel steel is symmetrically disposed on the four sides of the inner wall of the sleeve. Each pair of channel steel is opposite. The back of each channel steel is tightly abutted against the corresponding side of the box type profile steel. Each cross stiffening rib is welded by two grooved flat plates which intersect vertically. The clean steel box type profile steel buckling restrained brace is flexible in design, low in manufacturing cost, excellent in performance and high in adaptability.

Description

technical field [0001] The invention relates to a buckling-constrained support, in particular to a pure steel box-shaped steel buckling-constrained support. Background technique [0002] Earthquake is a highly destructive and random natural disaster, which will pose a huge threat to human life and property safety. The traditional seismic design relies on the structure itself to resist the earthquake, which is not only inefficient, but also the main structure will inevitably be damaged or destroyed during the earthquake, which will affect the normal function of the structure and lead to secondary disasters. From the point of view of energy conservation, the main reason for the collapse of structures under rare earthquakes is that their own energy dissipation capacity is not enough to consume the energy input into the structure by earthquakes, which leads to fatigue fracture and failure of key components such as nodes, beams, and columns of the structure. Installing energy-di...
