Description
Technical field
The invention belongs to civil engineering structure anti-seismic technology field, and in particular to a kind of applied to new in engineering structure
Self-resetting ductility bracing members.
Background technology
Earthquake is the one of the main reasons for causing structure to be interrupted or even collapsed using function, although existing structural seismic is set
Meter has met the requirement of " no collapsing with strong earthquake ", but because the random of earthquake of reciprocating vibration easily causes structure to occur under violent earthquake
Major injury, excessive residual deformation is produced after structure shake, so as to add the reparation difficulty after structure shake, is caused huge
Economic loss.Therefore, research and develop that residual deformation after a kind of shake is small, new lateral resistant member with runback bit function is to reduction structure
Economic loss is significant after earthquake, reduction shake.
At present, the main thought that existing Self-resetting bracing members are realized both at home and abroad is to use the consumption with full hysteretic characteristics
The combination of energy device and resetting means realizes power consumption and resets dual-use function.When meeting with geological process, carried by energy-dissipating device
For rigidity, bearing capacity, and power consumption is realized, residual deformation after the shake of structure is reduced using resetting means, reset function is realized.Runback

Under the effect of reciprocal axle power, the second upper end plate 22 drives support 25, the inside the 24, second T-shaped of support inside the first T-shaped
Five rectangular steel plates 5, the 6th rectangular steel plates 6, the 7th rectangular steel plates 7, the 8th rectangular steel plates 8, the first connecting plate 26, the second connecting plate
27th, inner support end plate 28 is moved, and lower end plate 20 drives square steel tube 19, the first rectangular steel plates 1, the second rectangular steel plates 2, the 3rd square
Shape steel plate 3, the 4th rectangular steel plates 4, the internal upper end plate 18 of end plate 17 and first are moved, the T of support 24 and the 2nd inside the first T-shaped
Support 25 is opposite with the outside direction of motion of square steel tube 19 inside shape.
（1）Such as second state diagram in Fig. 2, arrow represents axle power action direction in figure, inside two T-shaped support with
During outside 19 relative motion of square steel tube, inner support end plate 28 is contacted and moved with four first end anchorage 9-12, the first power consumption
Steel plate group（That is the first rectangular steel plates 1, the second rectangular steel plates 2, the 3rd rectangular steel plates 3, the 4th rectangular steel plates 4）Tension, the second consumption
Can steel plate group（That is the 5th rectangular steel plates 5, the 6th rectangular steel plates 6, the 7th rectangular steel plates 7, the 8th rectangular steel plates 8）Pass through inside end
The hole of plate 17 stretches out and not stressed, and the second connecting plate 27 promotes the second sliding block 30 axially movable, and the first sliding block 29 contacts outer
Hole slot on portion's square steel tube 19 is fixed, and is wrapped in two bar shaped shape memory alloys beams on two sliding blocks（That is first shape memory is closed
The golden marmem beam 32 of beam 31 and second）Tension, plays its super elastic characteristics and provides reset force.
（2）Such as the 3rd state diagram in Fig. 2, arrow represents axle power action direction in figure, inside two T-shaped support with
During outside 19 reverse motions of square steel tube, inner support end plate 28 and four first end anchorage 9-12 depart from, the first Wasted-energy steel plate group
（That is the first rectangular steel plates 1, the second rectangular steel plates 2, the 3rd rectangular steel plates 3, the 4th rectangular steel plates 4）Do not stress, four the second ends
Portion anchorage 13-16 is contacted with internal end plate 17, the second Wasted-energy steel plate group（That is the 5th rectangular steel plates 5, the 6th rectangular steel plates the 6, the 7th
Rectangular steel plates 7, the 8th rectangular steel plates 8）Tension, the first connecting plate 26 promotes the first sliding block 29 axially movable, the second sliding block 30
Hole slot on the outside square steel tube 19 of contact is fixed, and passes through two bar shaped shape memory alloys beams being wrapped on two sliding blocks（I.e. first
The marmem beam 32 of marmem beam 31 and second）Tension, plays its super elastic characteristics and provides reset force.
（3）To sum up, there is one group of tension in the first Wasted-energy steel plate group and the second Wasted-energy steel plate group, now respective rectangular steel plate is sent out
Power consumption effect is waved, the hysteresis loop obtained is in flag type pinch shape, and is only distributed in one, three quadrants；Therefore, only need considerably less
Reset force be can be achieved preferable reset effect；Under the effect of reciprocal axle power, the shape note in SMA Self-resetting ductility bracing members
Recall alloy beam and be in tension state all the time, can so reduce SMA consumptions；When there is larger axial displacement in bracing members, shape
Memorial alloy Shu Huicong austenites turn to martensite, produce phase transformation power consumption, this also provides certain energy dissipation capacity for bracing members；Cause
This, rectangular steel plates and marmem beam cooperation with pinch hysteretic characteristics, the hysteresis loop of synthesis is in obvious
Flag shape, residual displacement is almost nil, and reset effect is good；When the support needs the larger axial bearing capacity of offer and axial direction
During rigidity, the consumption of rectangular steel plates can be increased, steel support shaft so can be achieved to bearing capacity and the controllable purpose of axial rigidity；Together
When, it will not excessively increase the consumption of the marmem beam for realizing reset function again.
This new SMA Self-resetting ductility bracing members take full advantage of the rectangular steel plates with pinch hysteretic characteristics and provided
Axial bearing capacity, axial rigidity, energy dissipation capacity, reset function is provided and larger axle using marmem beam for bracing members
To deformability, the Self-resetting bracing members costs of manufacture of itself can be reduced, rehabilitation cost after structure shake is also reduced, protects
The main bearing member of structure.
