Description

The super-elasticity anti-buckling energy-consumption supports
Technical field
The utility model relates to building construction vibration control field, and particularly a kind of super-elasticity anti-buckling energy-consumption supports.
Background technology
It is good as a kind of performance that anti-flexing supports, and the support force that provides is big, and earthquake acts on the stable member of lower stress repeatedly, is applied in increasing engineering just gradually.The U.S. and Japan have altogether and have adopted anti-flexing to support in hundreds of the buildings, and our country also has the part building to bring into use gradually, along with people to the going deep into of its performance study, its application prospect is boundless.
The anti-flexing of having developed at present is supported with polytype, but the difference of these supports mainly is two aspects, most importantly the type of buckling-restrained member is different with structure, but principle is all the same, adopt concrete filled steel tube as buckling-restrained member such as being typically, what also have adopts steel concrete as buckling-restrained member in order to save cost, but poor performance some, also have for easy direct employing steel pipe as buckling-restrained member; Be the different non-cohesive material of research on the other hand, attempt to find better non-cohesive material, make buckling-restrained member only provide lateral restraint as far as possible, do not participate in or few directly opposing axial load that participates in the core primary structure member.But these existing researchs lack enough concerns to the core primary structure member that anti-flexing supports, what adopt at present all is common steel member, also there is part to adopt low-yield steel member, but the subject matter that these core primary structure members exist is, because the core primary structure member that anti-flexing supports under middle shake or big shake is surrendered, therefore must change after the shake, increase the maintenance and reinforcement cost of structure.
Marmem is a kind of intellectual material with shape memory effect, super-elasticity and high damping characteristic, its maximum elastic strain can reach 10%~12%, that is to say that it has not only realized the highly energy-consuming effect under the situation of big strain, and do not produce permanent set substantially.Utilize the energy consumer of super elastic shape memory alloy effect design to compare, have durability, corrosion resistance and good, life cycle length, allow series of advantages such as large deformation and distortion can recover with other metal energy consumer.But the research overwhelming majority who utilizes marmem to consume energy in the civil engineering utilizes shape-memory alloy wire to consume energy at present, earlier shape-memory alloy wire is carried out pre-stretch-draw during application, avoids it that pressurized flexing takes place.But the serious like this application that limits marmem, at first the diameter of shape-memory alloy wire is very little, and the restoring force that provides is very little, and energy dissipation capacity is limited; When using, next carries out pre-stretch-draw, and both loaded down with trivial details and utilized a part of strain of marmem, be unfavorable under big shake, using, otherwise be easy to generate the consequence that quilt is broken big shake play.
Therefore, develop a kind of good characteristic that not only has general anti-flexing support, and energy dissipation capacity is strong, the anti-buckling energy-consumption that need not to change after earthquake supports and just seems both urgent and meaningful especially.
Summary of the invention
Exist the core primary structure member to need the weak point of changing after shake in order to overcome present anti-buckling energy-consumption support, the utility model provides a kind of need not after shake to change, and the super-elasticity anti-buckling energy-consumption that consumes energy effective supports.
The technical scheme that the utility model adopted is that a kind of super-elasticity anti-buckling energy-consumption supports, comprise the core primary structure member, buckling-restrained member, non-cohesive material between core primary structure member and buckling-restrained member, and the end connecting elements that is connected with core primary structure member two ends, it is characterized in that being that the core primary structure member vertically is made of two parts along rod member, a part is the super-elastic shape memory alloy part, another part is steel or other alloy parts, connect together by welding or mechanical connection manner between two parts member, this two-part cross sectional shape is similar, the corresponding size in cross section can be the same or different, and the end connecting elements is by steel, shape memory alloy material or other alloy material are made.
Described core primary structure member can all be made by super-elastic shape memory alloy bar or sheet material.
Described core primary structure member will guarantee that the marmem part is than steel or the surrender in advance of other alloys part when earthquake.
Described core primary structure member and end connecting elements can adopt shape memory alloy material to make simultaneously all.
Yi word pattern or cross or I shape or round or circular ring type or ellipse can be adopted in the cross section of described core primary structure member or lattice is combined or along bar longitudinal variable cross-section type or along the vertical open cell type of bar or along bar lateral opening type.
Described buckling-restrained member can be concrete filled steel tubular member, one heavy or multiple steel tube confinement member, reinforced concrete member, the confining part that polylith steel plate or reinforced concrete prefabricated board are joined together to form by high-strength bolt, the confining part that the cast mortar forms in the steel pipe is filled the confining part that other high strength non-cohesive materials form in the steel pipe.
Described non-cohesive material can be that epoxy resin or asphalt varniss or ethene basic unit add foam or rubber layer or silicone rubber layers or silicones and add epoxy resin or polyethylene sheeting or butyl rubber.
The utlity model has following remarkable advantage:
(1) shake back free of replacement.Compare present existing anti-buckling energy-consumption and support, the utility model biggest advantage is exactly super-elasticity anti-buckling energy-consumption support can also continuation use after the earthquake, need not to change, and has saved the cost of maintenance and reinforcement.
(2) power consumption is effective.Since the high damping characteristic that marmem has, the core primary structure member that utilizes marmem to support as power consumption, and a large amount of seismic energies can dissipate under geological process.
(3) good endurance.Because marmem is compared general steel and had good endurance, therefore the characteristics of good corrosion resistance, adopt marmem as the core primary structure member, and the performance that the super-elasticity anti-buckling energy-consumption supports can remain unchanged for a long time substantially, and performance degradation is little.
The utility model can be used in the various building structure, such as frame construction, the frame-shear wall structure, in the large-span structure, when enough lateral support power was provided to structure, a large amount of seismic energies not only can dissipate, and after shake free of replacement, saved the maintenance and reinforcement cost of building, significant, will be widely used in all kinds of building construction vibration controls field.
