Description
Technical field
The utility model belongs to energy dissipation brace construction applications, more particularly to a kind of the anti-buckling of assembled GFRP steel constraint
Energy dissipation brace.
Background technique
Structure systems with energy dissipation is compared with traditional Aseismic Structure System, in safety, economy and technological rationality
Aspect will be more superior.The basic principle of traditional anti-seismic structure is by the anti-seismic performance of enhancing structure (intensity, just itself
Degree) resist geological process, i.e., it stores, convert by the damage of structure itself and supporting member and earthquake energy.Knot
Structure shock resistance depends primarily on the ability of elastic-plastic deformation and hysteretic loop energy dissipation capacity of structure, and structure itself does not have self
The ability of adjusting, it may be said that be passive passive earthquake resistant construction.
Due to being equipped with non-bearing dissipative member (energy dissipation brace, energy-consuming shear wall etc.), they have structure systems with energy dissipation
There is biggish energy dissipation capacity, dissipative cell energy rate is introduced into energy consumption state in macroseism, consumes the seismic energy in input structure
And the earthquake response of attenuating structure, protect main structure and component from damage, so that it is guaranteed that safety of the structure in macroseism.
Passive Energy Dissipation Structures are the earthquake responses that structure is reduced by way of " flexible energy dissipation ", and main structure and the energy dissipator division of labor are bright
Really, the supporting member of main structure is responsible for bearing primary load, and energy dissipator and nonload bearing element, only undertakes and provides for structure
Larger damping, the effect of the seismic energy of dissipation input structure.On the one hand can reduce in this way the setting of structural elements, section and
Arrangement of reinforcement, on the other hand due to the coordination of energy dissipator, dissipated a part of seismic energy, to improve structure entirety
Quake-resistant safety degree.Engineering data shows using seismic energy dissipation structure system, for new building can save structure 5%~
10% cost.With the continuous development of Building technology, high-strength light material is more and more used, and structural elements section is got over
Next smaller, height of house is higher and higher, and structural span is also increasing, to meet the requirement of earthquake-resistant structure, can not use
The simple strength and stiffness by component in traditional aseismic theory, the method that earthquake is resisted in a manner of " very stiff and demanding ", and
Passive Energy Dissipation Structures are then more prone to " defeating a force with a tenderness ", and structure is higher, more soft, span is bigger, and energy-dissipating and shock-absorbing effect is more significant.
Thus, Passive Energy Dissipation Structures more adapt to the development of modern building technology.
In present architectural structural system, frame structure and frame-brace structure are using very extensive.Pure frame structure
Anti-side rigidity is limited, and under earthquake and high wind load action, lateral displacement is larger, limits its application height.Frame-brace
Structure solves the problems, such as structure anti-side rigidity to a certain extent, but when it is pressurized under severe earthquake action, to be also easy to produce buckling existing
As easily causing the destruction and failure of support itself or connection, while supporting the Hysteresis Behavior after buckling less able, being difficult to have
The energy consumption of effect reduces the shock resistance of structure.To solve the problems, such as support compressive buckling, it is anti-that some scholars develop a kind of energy
The supporting member of anti-bend song, referred to as buckling-restrained energy-dissipation.Buckling-restrained energy-dissipation is generally made of 3 parts, i.e., core cell,
Constraint element and sliding mechanism unit.Common buckling-restrained energy-dissipation includes two types, i.e. grouting-type and clean steel type.Grouting
Type refers to that constraint material is concrete material, and clean steel type then refers to the case where steel are used only in entire product.Grouting-type product is early
Phase product, in various countries using relatively broad, and clean steel type is then opposite develops later, but since its own is with the obvious advantage, has started
It is used in various countries' large area.But the buckling-restrained energy-dissipation of both types is there are a common issue, is exactly support device
Own wt is too big, brings very big inconvenience to installation and application.
