Description
Technical field
The present invention relates to the building engineering structure antivibration area, relate in particular to a kind of change type buckling-restrained energy-dissipation.
Background technology
Since time decades recently, buckling-restrained energy-dissipation is more in the application of the countries and regions such as the U.S., Japan, China Taiwan.Buckling-restrained energy-dissipation is a kind of support that flexing does not occur under tension and pressured state, supports to compare with tradition to have more stable mechanical property.Not only can improve rigidity and the ductility of structure by buckling restrained brace, and utilize the Hysteresis Behavior of steel can consume due to the upper energy of horizontal loads in structure, the shock resistance of structure is improved very large meaning.After the nineteen ninety-five Kobe earthquake, anti-buckling constraint support system is used in a large number in Japan, has surpassed so far 300 buildings and has used buckling-restrained energy-dissipation; In the U.S., more than 30 Application in Building are arranged also; Taiwan in China is used also more.The technology that buckling-restrained energy-dissipation is relevant and method for designing research have the time of more than ten years, but the research application still is in the starting stage at home, and Engineering Projects is less, and product is used take external product as main, and cost is very high, and engineering is used and is difficult to promote.Used the building of buckling restrained brace that hundreds of is arranged by 2008, yet domestic in this respect research still is in the starting stage, Engineering Projects is less, and product is used take external product as main, so cost is higher.
General buckling-restrained energy-dissipation is made of five parts: constraint surrender section, the non-surrender section of constraint, without the non-surrender section of constraint, without boning expandable material and surrender constraint mechanism.Buckling-restrained energy-dissipation various informative, but operating principle is substantially similar.That is: support under external force, load is all born by core, and core can be surrendered power consumption under axial tension or pressure-acting, and peripheral constraint mechanism offers the crooked restriction of core, flexing when avoiding the core pressurized.Due to poisson effect, can expand during the core pressurized, therefore be provided with the gap between core and constraint mechanism, with reduce core when stressed to the constraint mechanism pinch.
At present, there is following problem in existing buckling-restrained energy-dissipation:
The buckling-restrained energy-dissipation that existing product relates to is mainly to smear the thick non-cohesive material of one deck 2mm by steel plate (shaped steel) surface, and form the gap between constraint mechanism, the good results are evident to constraint for the size in gap, therefore very high to the requirement of making, therefore when buckling-restrained energy-dissipation core primary structure member adopts non-" one " shaped sections form, will affect significantly confining part to the binding effect of core primary structure member.
Buckling-restrained energy-dissipation when needs design large-tonnage type, or be when building has higher requirements, the thickness of section of core primary structure member will be very thick (when adopting " one " shaped sections, behind the cross section, thickness is thicker), be unfavorable for that buckling-restrained energy-dissipation connects with agent structure, affected the operability of buckling-restrained energy-dissipation and agent structure connection construction and safety etc., made technology difficulty increase, cost rises.
When the core primary structure member of buckling-restrained energy-dissipation adopts thinner cross section, the apparent size of buckling-restrained energy-dissipation will be larger, restraint device can not get sufficient utilization to the effect of contraction of core primary structure member, reduced the economy of buckling-restrained energy-dissipation, and the apparent size of existing all kinds of buckling-restrained energy-dissipations is more difficult satisfies building requirements.
Traditional buckling-restrained energy-dissipation is when work, and because outer constraint sleeve weight is very large, during structural vibration, slippage easily occurs for core and outer sleeve, supports thereby destroy.
