Description
Technical field
The present invention designs a kind of assembling type steel structure H profile steel Self-resetting energy dissipation brace device, belongs to Structural Engineering technology neck
Domain.
Background technology
As one of natural calamity, the survival and development to the mankind cause great threat for earthquake, and cause greatly
Economic loss.It is western that China is located at Pacific Rim volcanic earthquake band, is one of country of earthquake disaster most serious in the world, institute
Quake evaluation with building structure is an important job.The method for resisting earthquake is developed at this stage by initial antidetonation
Damping.Frame-Bracing Systems are one of common dual lateral resisting structure systems, and supporting structure can undertake major part
Horizontal shear, reduces integrally-built horizontal displacement.Flexing easily occurs under geological process for traditional central support structure, causes
Brittle fracture influences integrally-built bearing capacity；Traditional eccentrically braces structure system, energy consumption beam-ends plastic deformation is larger, shake
After be difficult to repair；It is anti-buckling be supported on big shake effect after residual deformation it is larger, corresponding overall structure residual deformation is also larger, shake
After be difficult to repair.For these deficiencies, people have also been proposed self reset curvature-prevention support, and under geological process, Self-resetting is prevented bending
Song, which supports, can provide the anti-side rigidity of structure and the seismic energy that dissipates, and after geological process, be supported on the work of Self-resetting mechanism
Returned to original state under, and then reduce the residual deformation of total.But after shake, support energy consumption kernel destroys
When, it is necessary to replace whole support, it is impossible to realize that only replacing the kernel mechanism that energy consumption acts on repairs the purpose of support, not only applies
Work inconvenience, and steel are wasted, rehabilitation cost is also higher, and the arrangement supported influences the arrangement of door and window.And rope supporting structure
The deformation of middle rope is too big, and Suo Li increments are big, and structure cannot produce enough horizontal displacements to meet earthquake resistant code to ductility construction
Requirement.
The content of the invention
The present invention proposes a kind of assembling type steel structure H profile steel Self-resetting energy dissipation brace for belonging to technical field of structural engineering
Device, the defects of its object is to overcome the prior art, makes structure under geological process, passes through leverage amplification support bottom
The deformation of cable wire allows capital to produce enough horizontal displacements for meeting shockproof requirements.Bracing members are as energy consumption and Self-resetting system
System, can reduce or avoid agent structure from damaging, and dissipation seismic energy and reduction geological process, minimize structure residual deformation,
Rehabilitation expense and its indirect economic loss after shaking are reduced, embodies the advantage of steel construction.

Use, base is connected with Vierendeel girder and column is connected with underbeam, may make up frame-Bracing Systems, and do not influence
The setting of frame space door and window.
Axis pin is fixed on base in the center of steel plate I, steel plate II, steel plate II so that steel plate I can be using axis pin in
The heart rotates, and forms lever mechanism, and brass sheet is attached on steel plate I；In column capital, horizontal displacement effect lower pillar stand rotates, and passes through
Leverage centered on axis pin, makes the rotation of steel plate I, so as to be rubbed by brass sheet with steel plate II to consume energy；
Cable wire passes through the default hole in column lower part, and is fixed with anchorage, and end applies pre- through pullover and by anchorage
Clamp force fixes it simultaneously can adjustment structure rigidity；Under the horizontal force action of column capital, dissipative system rotates, the pullover of its both sides
It is extruded and is deflected outward, extend cable wire, steel cable stretching force increase, after horizontal force disappears, steel cable stretching force is as elastic restoring force
Dissipative system is set to return to original position, so that structure has runback bit function.
The bottom cable wire deformation of the support device is amplified by lever principle, makes to produce enough horizontal displacements at the top of column
To meet requirement of the earthquake resistant code to ductility construction maximum story drift, and amplification factor is by adjusting bearing height and cable wire
Position is realized.
Consumptive material can be reduced using H profile steel, avoids the wasting of resources.
Beneficial effect
The drag-line supporting structure of conventional frame-Bracing Systems, when being subject to capital horizontal force action, due to rope
Deformation is big, and corresponding Suo Li increments are big so that system cannot produce enough relative storey displacements for meeting shockproof requirements；It is and of the invention
Support bottom cable wire deformation very little, this deformation amplified, makes that at the top of column enough horizontal displacements can be produced by lever principle
To meet requirement of the earthquake resistant code to ductility construction maximum story drift, and amplification factor can adjust branch according to being actually needed
Support height is realized with cable wire position；Under the horizontal force action of capital, dissipative system rotate, the pullover of its both sides be extruded and to
Extrinsic deflection, extends cable wire, and steel cable stretching force increase, after horizontal force disappears, steel cable stretching force makes dissipative system as elastic restoring force
Original position is returned to, so that structure has runback bit function, so as to reduce the residual deformation of structure, structure is had certainly
Reset function；The friction of latten(-tin) and steel plate is consumed energy when structure is rotated by dissipative system.Compared to traditional inclined support structure, sheet
Invent as rising structure and be H profile steel support, setting and the consumptive material for not influencing door and window be few.After earthquake, the spiral shell of dissipative system
Bolt is easily changed to carry out the reparation of structure when destroying, and vertical supporting is easy for installation, reduces the workload of site operation,
A large amount of manpower and materials have been saved, have reduced the construction period.
