Abstract
The invention relates to a novel compound energy-dissipation and shock-reduction support. The novel compound energy-dissipation and shake-reduction support comprises a core veneer, an outer sleeve, L-shaped steel plates, rectangular steel plates, viscous-elastic materials and bolt holes. The outer sleeve is sleeved outside the low-yield steel core veneer, the rectangular steel plates are welded on one sides of ends of the outer sleeve. The viscous-elastic materials are filled between the rectangular steel plates and the L-shaped steel plates. The L-shaped steel plates are welded with the core veneer and are connected with the structure through the bolt holes formed in two ends of the core veneer. The support cannot lead to buckling when bearing pressure under the action of earthquake. The low-yield steel core veneer generates repeated tension pressing deformation, meanwhile the viscous-elastic materials generate shear deformation, and the low-yield steel core veneer and the viscous-elastic materials dissipate earthquake energy together. The viscous-elastic materials begin to dissipate energy once relative displacement happens between the outer sleeve and the core veneer. Under the same deformation condition, the viscous-elastic materials and the buckling-restrained support dissipate energy together, and the support has a larger energy-dissipation capacity compared with a traditional buckling-restrained support. A layer number and a size of a viscous-elastic material layer can be flexibly designed according to need.
Description
Technical field
The present invention relates to novel mixing energy-dissipated brace, belong to engineering structures antidetonation and energy-dissipating and shock-absorbing technical field.
Background technology
Traditional structure in resisting the process of earthquake, is that nonlinear deformation and the damage by architectural structure system consumes the energy of earthquake motion input.This is a kind of antidetonation strategy that relies on structure itself, and anti seismic efficiency is remarkable not, and can bring the destruction of structural system, causes rehabilitation expense after very large shake.Along with the development of structural damping technology, seismic isolation device just is widely used, and its principle is to consume or isolate the seismic energy of considerable part by seismic isolation device, thereby reduces the damage of structure, guarantees the safety of structure.Traditional buckling restrained brace is wherein a kind of, i.e. outer sleeve on low surrender steel core plate outer race is generally with the arranged in form of the diagonal brace interlayer diagonal position in building structure.Under geological process, the tension and compression deformation repeatedly of the central layer seismic energy that can dissipate, outer sleeve has effectively prevented again the flexing of central layer simultaneously, and providing of the lasting power consumption supported and rigidity has been provided.
Because outer sleeve is directly not stressed, almost not distortion, and central layer has tension and compression deformation repeatedly under geological process, particularly at the two ends of central layer, the distortion between the relative outer sleeve of central layer is especially large.If by appropriate design, steel plate is welded on respectively on outer sleeve side and central layer, and fill the viscoelastic material with highly energy-consuming characteristic between steel plate, the relative deformation between outer sleeve and central layer can drive the shear strain of viscoelastic material and jointly consume energy.In outer sleeve and central layer generation relative deformation hour, surrender occurs not yet and during power consumption, viscoelastic material namely begins shear energy dissipation at central layer; , sheared and the common power consumption of central layer surrender by viscoelastic material when larger in outer sleeve and central layer generation relative deformation.This is equivalent to the combination of buckling restrained brace and viscoelastic damper, thereby effectively improved the energy dissipation capacity of device, for the damage that reduces structure in seismic process with repair after alleviating shake, guarantee that people's safety of life and property is significant.
Summary of the invention
The object of the present invention is to provide novel mixing energy-dissipated brace, outer sleeve on low surrender steel core plate outer race makes central layer under geological process, tension and compression deformation occur and consumes energy, and outer sleeve prevents that effectively central layer from surrendering to guarantee the lasting power consumption of central layer; Fill simultaneously the viscoelastic material with highly energy-consuming characteristic between the steel plate that is welded on respectively on outer sleeve side and central layer, the shear strain that drives viscoelastic material by the relative deformation between outer sleeve and central layer is consumed energy, thereby has effectively improved the energy dissipation capacity of device.
The present invention is novel mixing energy-dissipated brace, comprise central layer, outer sleeve, L shaped steel plate, rectangular steel plates, viscoelastic material and bolt hole, wherein: two central layers insert respectively outer sleeve two ends, outer sleeve end sides welding rectangular steel plates, L shaped steel plate and central layer welding, fill viscoelastic material between rectangular steel plates and L shaped steel plate, described shock-absorbing support is connected with structure by the bolt hole at central layer two ends.
This device can be so that be supported on unlikely flexing when bearing pressure under geological process; And low surrender steel core plate is when producing repeatedly tension and compression deformation, and viscoelastic material can produce shear strain, both seismic energies that jointly dissipate.The present invention's viscoelastic material when in a single day outer sleeve and central layer relative displacement occurs begins power consumption, has overcome the drawback that traditional buckling restrained brace does not consume energy under little shake; Under identical large deformation condition, jointly consumed energy by viscoelastic material and buckling restrained brace, more traditional buckling restrained brace has larger energy dissipation capacity; The number of plies of viscoelastic material layer and size be flexible design as required.Conceptual Design of Earthquake Resistance of the present invention is clear, Structural Tectonics is simple, material therefor is with low cost, and easy construction is convenient to change.
In the present invention, central layer 1 adopts low surrender steel core plate, and what outer sleeve 2, L shaped steel plate 3 and rectangular steel plates 4 were used is common iron.
In the present invention, outer sleeve 2 can be square steel pipe or round steel pipe.
In the present invention, the cross section of central layer 1 can be yi word pattern or cross.When the cross section of central layer 1 is in-line, between central layer 1 and outer sleeve 2, packing material mortar 7 must be set, be coated with between packing material mortar 7 and central layer and have or not binding material 8.
In the present invention, viscoelastic material 5 is the viscoelastic material of high-damping rubber or similar tool highly energy-consuming characteristic.
In the present invention, in outer sleeve 2 sides, and leave the gap between L shaped steel plate 3 to prevent friction; In outer sleeve 2 ends, and leave the distortion of sufficient space to guarantee that viscoelastic material layer is enough between L shaped steel plate 3.
In the present invention, the number of plies of viscoelastic material 5 and size be flexible design as required, only L shaped steel plate 3 and rectangular steel plates 4 alternately need to be welded on central layer 1 and outer sleeve 2 sides, and fill viscoelastic material 5 between L shaped steel plate 3 and rectangular steel plates 4, just can realize using the purpose of multilayer viscoelastic material.
Compare with traditional buckling restrained brace, advantage of the present invention is:
(1) viscoelastic material can not retrain and affect the tension and compression deformation of low surrender steel core plate, can not affect the energy dissipation capacity of central layer;
(2) under little earthquake situations condition, as long as central layer begins distortion, no matter whether central layer is surrendered, and all can drive the shear strain of viscoelastic material, makes it begin power consumption, and this has overcome the drawback that traditional buckling restrained brace is unyielding under little shake, do not consume energy;
(3) under large earthquake situations condition, along with the increase of central layer distortion, the energy dissipation capacity of viscoelastic material also constantly increases, and the more seismic energy that can effectively dissipate reduces the damage of structure;
(4) size of flexible design buckling restrained brace as required, the number of plies of flexible design viscoelastic material and size;
(5) material therefor is with low cost, Structural Tectonics is simple, easy construction, be convenient to change, and damping effect is good.
