Field.
Background technique
Earthquake has great destructive power, brings incalculable damage to society, therefore increase seismic region structure
Ductility and energy dissipation are necessary.Using metal damper be improve structural seismic performance effective and usability methods it
One, the mild steel damper designed at present includes rectangle, triangle, X-type, hollow diamonds etc., is mainly used for eliminating a large amount of input
Energy prevents the destruction of other main members.Two-stage or multilevel control system are in the same period to attract one kind of researcher new
Method makes structure to adapt to different external condition, to reach the safety of protection main structure.Branch in traditional steel construction
Support component can effectively increase the lateral rigidity of structure, reduce the sidesway of structure, but cannot increase structure ductility, can not
Earthquake energy.
Summary of the invention
In order to solve the deficiency on traditional support component technology, it is an object of the invention to propose that a kind of multistage energy consumption is concentric
Damper.The device is a kind of energy-consumption damper of multi-scale behavior with variable intensity and rigidity, can be in difference
Horizontal earthquake on dissipate seismic energy, secondly, can effectively increase structure ductility.
To achieve the goals above, the present invention adopts the following technical scheme that.
A kind of concentric damper of multistage energy consumption proposed by the present invention, including it is connecting plate 1, external energy consumption round tube 2, interior
Consume energy round tube 3, fixed piston 4 and fixed cylinder 5 in portion, in which: 4 one end of fixed piston is by being fixedly welded on internal energy consumption round tube
3, inside energy consumption 3 two sides of round tube are respectively provided with fixed piston 4, and fixed cylinder 5 is connected to external 2 inside of energy consumption round tube；Fixed piston 4
The other end protrudes into fixed cylinder 5, and fixed piston 4 can move back and forth in fixed cylinder 5；Make external energy consumption round tube 2, internal energy consumption
Round tube 3 passes through fixed cylinder 5 and is connected with fixed piston 4, and there are gaps between outside energy consumption round tube 2 and internal energy consumption round tube 3, and
And it is determined by the bending stiffness of external energy consumption round tube；Outside energy consumption round tube 2 and internal energy consumption round tube 3 are arranged concentric, no outside
When incentive action, outside energy consumption round tube 2 and internal energy consumption round tube 3 are completely independent；When external action is smaller, structure generates lesser
Lateral displacement, only external energy consumption round tube 2 deform dissipation energy；When external action is larger, outside energy consumption round tube 2 and inside
The round tube 3 that consumes energy works together, and deforms, and energy dissipation level is significantly increased, to reduce the damage of main member
Degree.
In the present invention, outside energy consumption round tube 2 and internal energy consumption round tube 3 are seamless steel pipe, can be in inside energy consumption round tube 3
Continue nested round tube.
In the present invention, the diameter ratio of outside energy consumption round tube 2 and internal energy consumption round tube 3 is 1.5 ~ 2, outside energy consumption round tube 2
Be 15 ~ 25 with the ratio between the diameter of internal energy consumption round tube 3 and thickness, between outside energy consumption round tube 2 and the internal round tube 3 that consumes energy between
Gap is the 0.05-0.07 of external energy consumption 2 overall diameter of round tube.
In the present invention, outside energy consumption round tube 2 and fixed cylinder 5, internal energy consumption round tube 3 and fixed piston 4 are all made of welding
Connection, and round tube is locally thickeied in junction.
In the present invention, the failure load of the concentric damper of multistage energy consumption is less than the Critical Buckling Load of supporting member.
Compared with prior art, advantages of the present invention is as follows:
1) present invention is a kind of energy-consumption damper of multi-scale behavior with variable intensity and rigidity, can be different
Dissipate seismic energy on horizontal earthquake.
2) applicability of the present invention is high, can effectively increase structure ductility.
