Abstract
The invention discloses a kind of sleeve pipe constraining anti-buckling support with symmetrical initial imperfection, it is characterised in that：It is made up of end restraint section, flexing section and sleeve pipe three parts, both ends, which are bolted, is connected that shape is integral with beam, post component or node, to reach the purpose of the anti-side rigidity of increase component.Supported using the sleeve pipe constraining anti-buckling with symmetrical initial imperfection, under small shake effect, this buckling restrained brace keeps elasticity, and in middle shake or big shake effect, flexing section enters yielding stage, and its good hysteretic energy performance can play the effect of damper again.Sleeve pipe constraining anti-buckling with symmetrical initial imperfection supports the shaping that can be prefabricated in the factory, and ensure that component quality, reduces Contraction in Site workload, energy-conserving and environment-protective.
Description
Technical field
The invention belongs to building structure technology field, is constrained more particularly to a kind of sleeve pipe with symmetrical initial imperfection anti-
Buckling support, suitable for steel construction or concrete structure with buckling restrained brace.
Background technology
During steel construction or reinforced concrete structure use, common support, which is pressurized, can produce flexing phenomenon, work as branch
After supportting compressive buckling, rigidity and bearing capacity drastically reduce.Under earthquake or wind action, the internal force of support is being pressurized and tension two
Back and forth change under kind state.When support gradually fades to tension state by the state of buckling, the internal force and rigidity of support are close to
Zero.Thus common support Hysteresis Behavior under course under cyclic loading is poor.To solve common support compressive buckling and hysteresis
Can be poor the problem of, sleeve pipe is set outside support, constrains the compressive buckling of support, forms buckling restrained brace only core plate and other
Component is connected, and suffered load is all undertaken by core plate, and outer sleeve and packing material only constrain core plate compressive buckling, core plate is existed
Tension and by pressure can enter surrender, thus, the Hysteresis Behavior of buckling restrained brace is excellent.Buckling restrained brace on the one hand can
The defects of to avoid common support tension and compression bearing capacity significant difference, the on the other hand energy dissipation capacity with metal damper can be with
Serve as in the structure " fuse " so that agent structure is substantially in elastic range.Therefore, the application of buckling restrained brace,
Anti-seismic performance of traditional support frame under middle shake and big shake can be improved comprehensively.
The content of the invention
Goal of the invention：Because existing constraining anti-buckling is supported under course under cyclic loading, it is connected with buckling restrained brace

On the common support of system, a kind of sleeve pipe constraining anti-buckling support with symmetrical initial imperfection is formed, is selected in engineering structure
Prioritizing selection when constraining anti-buckling supports.
Technical scheme：To achieve the above object, the technical solution adopted by the present invention is：
A kind of sleeve pipe constraining anti-buckling support with symmetrical initial imperfection, by end restraint section, flexing section and sleeve pipe group
Into the end restraint section is located at the both ends of the flexing section, and described sleeve pipe is enclosed in the flexing section, it is characterised in that：Institute
State flexing section to be made up of along the axis direction of support at least one Typical symmetrical initial imperfection unit, the single Typical symmetrical
Initial imperfection unit is made up of two identical initial imperfection units, and the initial imperfection unit is by four in the same plane
Identical parallelogram plate by folding the space body formed composition, four parallelogram plates two-by-two it is conllinear simultaneously
A summit is intersected at, according to respectively parallelogram plate one, parallelogram plate two, parallelogram plate three are peaceful counterclockwise
The common edge of row quadrangular plate four, wherein parallelogram plate one and parallelogram plate two, parallelogram plate two with it is parallel
The common edge and the common edge of parallelogram plate three and parallelogram plate four of quadrangular plate three are crest line, parallelogram plate
One and the common edge of parallelogram plate four be valley line, adjacent parallelogram plate is foldable outwardly along crest line, along valley line
To interior folding, until four free margins of parallelogram plate are on same level, the outward folding refers to adjacent parallel
Angle between the exterior normal of quadrangular plate becomes big, and the folder between the exterior normal of adjacent parallelogram plate is referred to interior folding
Angle diminishes；Described sleeve pipe is fixed on the outside of flexing section by grout filling concrete.
The connecting plate that the end restraint section is reserved by components such as square plate, T-shaped short girder steel and beam columns forms, square bar
Plate weld is welded to connect in flexing section end, two T-shaped short girder steels with square plate, and connecting plate is clipped in two T-shaped short girder steels
Between, connecting plate is connected with T-shaped short girder steel with high-strength bolt.
Described sleeve pipe is made up of the hollow steel pipe of square-section.
Two identical initial imperfection units in the single Typical symmetrical initial imperfection unit are on quadrangular plate
The plane that four free margins are formed is symmetrical.
Four identical parallelogram plates can not be rectangle.
Beneficial effect：
A kind of sleeve pipe constraining anti-buckling with symmetrical initial imperfection of the present invention supports, by end restraint section, flexing section and
Sleeve pipe is formed.Supported using the sleeve pipe constraining anti-buckling with symmetrical initial imperfection, because tension and compression unbalance factor is smaller, favorably
In component or the bean column node such as protection beam column under geological process.Flexing section is made up of multiple Typical symmetrical initial imperfection units,
Typical symmetrical initial imperfection unit makes to be supported under geological process by the folding line formed by crest line and valley line pre-set,
Larger strain can occur at the folding line pre-set so as to form yield line, reach the purpose of dissipation seismic energy.This
Invention can only need the built-in fitting with components such as bolt and beam columns to be connected, both ensure that component matter in factory process to scene
Amount, the wet trade workload at scene, energy-conserving and environment-protective are reduced again.Sleeve pipe constraining anti-buckling support with symmetrical initial imperfection was both
Flexible arrangement with the anti-buckling support of general restriction, can more effectively dissipate seismic energy the advantages that, can solve and bend again
The problems such as component or larger joints that song constraint support is connected, there is good Popularizing of A.
