Description
Technical field
The present invention relates to civil engineering energy-dissipating and shock-absorbing technical field more particularly to a kind of Self-resetting energy dissipation brace devices.
Background technique
Support is used as lateral resistant member, can significantly improve the anti-side rigidity and anti-side horizontal force of main structure, mostly high-rise
Structure is widely used.But conventional steel brace is in the north ridge earthquake of the U.S. in 1994 and nineteen ninety-five Japan Kobe earthquake
Serious buckling and rupture failure occurs, this makes domestic and foreign scholars start that conventional steel brace is in depth studied and found
New supporting form, buckling restrained brace (Buckling-restrained brace, BRB) are exactly met the tendency of under these circumstances
And it gives birth to and is achieved in world wide and is widely applied.Buckling restrained brace is the axis that a kind of tension and compression are attained by total cross-section surrender
To primary structure member, there is more stable hysteretic behavior compared with traditional conventional steel brace component, it is double that this characteristic has it
Weight structure function, can based on structure necessary anti-side rigidity is provided and plays the effect of dissipative member.However, bending
The design and processing request of song constraint support are higher, and need to ensuring core material, still there are gaps with outer sleeve after stress, cover simultaneously
The positions such as cylinder, end and node consume a large amount of steel, and steel utilization ratio is not high.More importantly buckling restrained brace
Although aseismic fortification objects expected from structure can be realized by itself good energy consumption, it exists apparent residual after shaking
Remaining deformation, Self-resetting performance are poor.Core material can not be checked under the premise of not destroying outer sleeve, whether be difficult to directly determine after shake needs
It replaces.Not only cause its support itself to repair difficult, and make the difficulty of overall structure reparation larger, reparation it is economical at
This and time cost are higher, and the use function of structure is easy to cause to interrupt, and bring huge economic loss for society.
Above- mentioned information are only used for reinforcing the understanding to background of the invention disclosed in background technology part, therefore it can be with
Including not constituting the information to the prior art known to persons of ordinary skill in the art.
Summary of the invention
A main aspect of the invention is to overcome above-mentioned the deficiencies in the prior art, provide it is a kind of can earthquake energy
And the Self-resetting energy dissipation brace device that Self-resetting performance is good.
According to an aspect of the present invention, a kind of Self-resetting energy dissipation brace device, including fixed frame, supporting member and at least
A pair of of Self-resetting component.Two carryings that fixed frame includes fixed arm and one end is fixedly connected on the fixed arm and is parallel to each other
Arm；One end of supporting member is protruded between two load bearing arms, and at a distance between the fixed arm；It is at least a pair of
Self-resetting component is symmetrically disposed on the two sides of the supporting member；The Self-resetting component includes that one or more shape memories close
Gold, there are two the linking arms being parallel to each other and the energy consumption for being connected to two linking arms for each marmem tool
Arm, two linking arms are connected to the supporting member and the load bearing arm.
According to another aspect of the present invention, a kind of Self-resetting energy dissipation brace device, including fixed frame, supporting member and extremely
Few one group of Self-resetting component.Fixed frame includes that cross section is in the cylinder of polygon and the cylinder bottom for being connected to the cylinder one end；
Two cylinders are protruded into one end of supporting member, and at a distance between the cylinder bottom；Self-resetting component described in every group
Including multiple marmems being uniformly arranged along the supporting member circumferencial direction, each marmem has
Two linking arms being parallel to each other and the energy consumption arm for being connected to two linking arms, two linking arms are connected to institute
State supporting member and the cylinder.
As shown from the above technical solution, the advantages and positive effects of the present invention are:
In Self-resetting energy dissipation brace device of the invention, including the fixed frame to be linked together by Self-resetting component and support
Component, Self-resetting component include one or more marmems.When Self-resetting energy dissipation brace stress deformation, deformation will be concentrated
On marmem.Marmem not only has unique shape memory characteristic as a kind of high-performance metal materials
And superelastic properties, also there is superior anti-fatigue performance and corrosion resistance.Wherein, superelastic properties can not only provide runback
Capability, and energy consumption can be provided again.That is, on the one hand Self-resetting energy dissipation brace device of the invention plays consumption ground
Shake the effect of energy；After another aspect earthquake, since the super-elasticity effect of marmem can be such that support device restores
The effect of structure Self-resetting is realized to original state almost without residual deformation.

Gold 1, and multiple marmems 1 are arranged to multiple row (not shown) in the centerline direction along supporting member 4.
Illustrate its action principle for the U-shaped marmem 1 shown in Fig. 6 A: under geological process, Self-resetting consumption
The deformation of energy support device will focus in super-elastic shape memory alloy 1, play the role of earthquake energy and Self-resetting.
The bearing capacity characteristics of marmem 1 mainly determine by its width b, thickness t and diameter D, single U-shaped marmem 1
Initial yield bearing capacity F can estimate according to the following formula:
Wherein fyIt is the phase intensity adjustable of shape memory alloy material, b is the width of test specimen, and t is the thickness of test specimen, and D is examination
The diameter of part crooked radian.
The deformation range of marmem 1 is related with length h.The bearing capacity energy of Self-resetting energy dissipation brace device
Power can be determined by changing width b, thickness t, diameter D and the length h of U-shaped marmem 1, and then meet different requirements
Design requirement, flexible design.
It is power-racking test result figure of Self-resetting energy dissipation brace device shown in FIG. 1 referring to Fig. 9, Fig. 9.Runback hyte
Part includes two U-shaped marmems 1, and U-shaped marmem 1 uses NiTi material, U-shaped 1 size of marmem
Are as follows: t=5mm, D=40mm, b=20mm, h=30mm.As shown in figure 9, its displacement-bearing capacity hysteresis loop show it is good
Flag type hysteretic behavior, energy dissipation capacity with load deflection it is continuous increase and increase, and loading procedure almost without
Strength degradation and residual deformation have good self-resetting capability.
