Description
Technical field
The utility model relates to a kind of buckling restrained brace, specifically clean steel box-shaped shaped steel buckling restrained brace.
Background technology
Earthquake is the extremely strong natural calamity of a kind of destructiveness and randomness, brings grave danger can for human life and property safety.Traditional seismic design relies on structure self opposing geological process, and not only efficient is lower, and agent structure will be difficult to damage or destruction occur with avoiding in earthquake, can affect the normal usage function of structure, causes the generation of secondary disaster.From the viewpoint of the conservation of energy, the main cause that structure is collapsed under rarely occurred earthquake is the energy that the energy dissipation capacity of himself is not enough to consume the earthquake input structure, thereby causes the critical component generation fatigue fractures such as node, beam, post of structure to destroy.For building structure energy-consumption shock-absorption device being installed is to reduce structural earthquake damage effective means; it can absorb large energy in earthquake; make damage concentration in energy-consumption shock-absorption device itself, thereby play the protection agent structure, reduce the effect of structural key position component damage.
Usually buckling restrained brace has two kinds of principal modes, i.e. (1) buckling restrained brace take concrete filled steel tube as tied mechanism, and the buckling restrained brace deadweight of this type is larger, and the process-cycle is relatively poor, and processing technology is complexity comparatively also; (2) clean steel type buckling restrained brace, this kind support is by the effect of contraction of the realizations such as the steel bushing of putting more energy into to the power consumption unit, although deadweight is lighter, process velocity is very fast, cost also can correspondingly promote.
The core cell of buckling restrained brace has two kinds of buckling failure patterns, i.e. complete buckling and cripling under the axial compression effect.Existing clean steel type buckling restrained brace all is the generation that has limited these two kinds of buckling failure patterns of core cell by construction measures such as stiffening ribs.Common core cell has " one " font plate and " ten " font compound section and H shaped steel.But existing clean steel type buckling restrained brace has all been ignored a major issue when design, does not namely utilize the ability of core cell self opposing cripling.Cause the reason of this phenomenon to be, the section of core cell, the edge of a wing such as " one " font plate and " ten " font compound section and H shaped steel is the parts of encorbelmenting, cripling very easily occurs under the effect of axle power, therefore existing clean steel type buckling restrained brace can not utilize the ability of core cell self opposing cripling, has caused macroeconomic decline.
Summary of the invention
The utility model is intended to overcome the defective of prior art, and a kind of clean steel box-shaped shaped steel buckling restrained brace is provided, so that the design of buckling restrained brace is more flexible, cost is cheaper, and performance is better, and applicability is stronger.
In order to solve the problems of the technologies described above, the utility model is achieved in that
A kind of clean steel box-shaped shaped steel buckling restrained brace is characterized in that: it comprises a box-shaped shaped steel and a sleeve that is enclosed within box-shaped shaped steel outside;
Described box-shaped shaped steel is a rectangular tube, and symmetry is offered groove respectively in the middle part of the four edges at its two ends, is welded with the cross stiffening rib in the groove;
All be arranged with channel-section steel on four faces of described sleeve lining, every pair of channel-section steel arranges dorsad, and its back holds out against respectively each face of box-shaped shaped steel.
Described clean steel box-shaped shaped steel buckling restrained brace is characterized in that: described cross stiffening rib is that two flat boards with groove intersect vertically and are welded.
The beneficial effects of the utility model are: adopt the cross stiffening rib as the steel node, box-shaped shaped steel is as power consumption steel core, and make both transition and conversion by the rational structure measure, and adopt the measure of inserting channel-section steel at the local interval of restraining tube sleeve inner, reduced the bending length of core power consumption unit, guaranteed its resistance to overturning, and reduced to greatest extent steel using amount, so that the design of buckling restrained brace is more flexible, cost is cheaper, performance is better, and applicability is stronger.

The specific embodiment
Such as Fig. 1-shown in Figure 7: a kind of clean steel box-shaped shaped steel buckling restrained brace, it comprises a box-shaped shaped steel 1 and a sleeve 5 that is enclosed within box-shaped shaped steel outside; Box-shaped shaped steel is a rectangular tube, and symmetry is offered groove respectively in the middle part of the four edges at its two ends, is welded with cross stiffening rib 2 in the groove; As shown in Figure 8: the cross stiffening rib is that two flat boards 7 with groove intersect vertically and are welded.All be arranged with channel-section steel 3 on four faces of sleeve 5 inwalls, every pair of channel-section steel arranges dorsad, and its back holds out against respectively each face of box-shaped shaped steel.
As shown in Figure 9: described clean steel box-shaped shaped steel buckling restrained brace, its oblique support is arranged between column 8 and the back timber 9.
Four faces that form box-type section retrain each other and support, the ability of anti-cripling in the time of greatly strengthening its pressurized.According to China " Code for design of steel structures ", if be the rectangular tube form with the power consumption core design of buckling restrained brace, its flakiness ratio only need satisfy and is not more than
(
Be steel yield strength standard value) just can make its surrender power consumption and the cripling phenomenon does not occur, and this condition is to satisfy very easily.Utilize this characteristic and advantage of rectangular tube, it as the power consumption core, concerning the design of buckling restrained brace, only need be guaranteed that its resistance to overturning gets final product so.
