Description
Technical field
The utility model relate to anti-buckling bracing or strutting arrangement, and particularly a kind of lightweight of existing space structures can recover anti-buckling circular support device.
Background technology
Before the nineties in 20th century, traditional structural seismic method is by agent structure local yielding dissipation seismic energy, and as beam hinge etc., this energy dissipation mode causes main structure body to destroy, repair difficulty and cost after seriously adding shake, repair after being unfavorable for the shake of structure.After Japanese Osaka-Kobe earthquake and U.S.'s north ridge earthquake, anti-buckling support, as a kind of energy-dissipating and shock-absorbing component of superior performance, obtains in the developed country of many shakes such as Japan, the U.S. and applies fast, be also in developing stage in the research of China.Anti-buckling support is by limiting the flexural deformation of core component in core component outer wrapping constraint component, by core component tension and compression plastic strain dissipation seismic energy, common center support is equivalent under little shake effect, enough lateral rigidities are provided to structure, metal damper and dissipation energy is equivalent under medium and larger earthquake effect, so not only improve the ductility of structure but also given full play to the power consumption effect supported, making agent structure can not destroy or destroy less under geological process, be a kind of ideal energy dissipation mode.
At present, the cross section kind of anti-buckling support can be divided three classes according to restraining tube parts and combined situation: steel concrete restraining tube cross section, Steel concrete combination restraining tube cross section and all steel restraining tube cross section.Adopt steel concrete restraining tube cross section or Steel concrete combination restraining tube cross section, its Problems existing has: (1) structure manufacture required precision is high, manufacturing cost is caused to increase, special in fluid concrete, be difficult to ensure that the preset clearance between inner core component and peripheral constraint component meets the requirement of precision aspect; (2) wet trade such as fluid concrete brings impact to structure manufacture and construction, and its precision controlling difficulty is large; (3) be coated with the isolated material many employings epoxy resin being contained in inner core component surface, kind is single, its poor durability, is easy to depart from from core surface.For the anti-buckling support that constraint component required precision is higher, general employing all steel restraining tube cross section.
The core stressed member of anti-buckling support is generally be made up of the steel that yield point is lower, and section form has yi word pattern, cross and tubular type cross section etc.
Present stage, adopt pipe as the anti-buckling support of core stressed member, consider the requirement of constraint precision, deadweight and outward appearance, generally also adopt pipe as constraint component, but this can have influence on processing and the performance of anti-buckling support:
First, generally can reserve certain gap between anti-buckling supporting core parts and constraint component, and the size in gap is by decisions such as compression swellings by component.But for the anti-buckling support of pipe as constraint component, on market, existing round steel pipe is difficult to meet matched well relation between core stressed tube and confinement tube, if customization steel pipe, then cost can be larger.
Secondly, the stressed pipe of core as axial compression, not only have the compressive strain produced because of axial compression, the shearing strain produced because of torsion in addition, constraint pipe can not suppress the torsional deflection of the stressed pipe of core, and the existence of shearing strain will cause the local train of core stressed member to increase, reduce the fatigue behaviour of anti-buckling support.
In addition, adopt the connected mode of the anti-buckling support of dual, triple pipes and agent structure, generally at core tube welding edges one piece of end plate, be connected with agent structure by end plate, connected mode is comparatively single.
And existing anti-buckling bracing or strutting arrangement, weight is large, and its distortion can not recover automatically.
