The energy-consumption inner core component comprises a middle yield section and an end expanding section for component connecting. The section area of the end expanding section is larger than that of the middle yield section. The equal-section buckling constraining part is arranged on the outer periphery of the middle section of the energy-consumption inner core component. The reinforcing plate is fixedly connected between a flange of the energy-consumption inner core component and a web plate.

According to the parallel oblique plate buckling constraining support, overall and partial buckling of the energy-consumption inner core component is guaranteed, meanwhile, conflict with the reinforcing plate is avoided, so that the sections of the buckling constraining part are the same in the component length direction, the web plate chamfer of the energy-consumption inner core component does not need to be ground due to constraining requirements, and machining difficulty is obviously lowered.
Description
Technical field
The utility model belongs to field of civil engineering, relates to a kind of buckling restrained brace for reducing engineering structures seismic response.
Background technology
Before the nineties in 20th century, traditional structural seismic method is by agent structure local yielding dissipation seismic energy, and as machine-processed in beam hinge etc., this energy dissipation mode causes main structure body to destroy, after seriously having increased shake, repair difficulty and cost, be unfavorable for repairing after the shake of structure.From Japanese slope shake celestially with the ridge earthquake of U.S. north after, buckling restrained brace, as a kind of energy-dissipating and shock-absorbing member of superior performance, has obtained applying fast in the developed countries of shaking such as Japan, the U.S. more, in the research of China also in developing stage.Buckling restrained brace limits the flexural deformation of core component in core component outer wrapping constraint component, by core component tension and compression surrender dissipation seismic energy, under little shake effect, be equivalent to common center support, provide enough lateral rigidities to structure, under medium and larger earthquake effect, be equivalent to metal damper and dissipation energy, so not only improve the ductility of structure but also given full play to the power consumption effect of supporting, making agent structure under geological process, can not destroy or destroy less, be a kind of comparatively desirable energy dissipation mode.
At present, the cross section kind of buckling restrained brace can be divided three classes according to restraining tube material 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, the problem of its existence has: (1) structure manufacture required precision is high, cause manufacturing cost to increase, in the time of fluid concrete, be difficult to guarantee that the preset clearance between inner core component and peripheral constraint component meets the requirement of precision aspect especially; (2) wet trade such as fluid concrete is given to make with construction and has been brought impact, and its precision control difficulty is large; (3) be coated with the isolated material that is contained in inner core component surface and adopt epoxy resin more, kind is single, and its poor durability is easy to depart from from core surface.
In addition, adopt the buckling restrained brace in all steel restraining tube cross section, if that its inner core component adopts is I-shaped, cross, T shape member etc., because there is chamfering or weld seam in the edge of a wing and the web junction of inner core component, some buckling restrained braces are for realizing the perfect laminating of restraining tube parts inner core component, need the knuckle of chamfering or the constraint component of mechanical grinding inner core component, obviously like this can increase construction complexity, easily cause again the mechanical damage to kernel constraint component.As adopted the flexing of four the comprehensive constraint energy consumption inner core of angle steel members in prior art example (patent CN101974949B), can increase mechanical grinding operation because of the chamfering of cross core component or weld seam equally; On the other hand, buckling-restrained parts in technical examples CN201190347Y are welded to form square tube by two angle steel, in order to realize square buckling-restrained parts cylinder interior angle fitting tightly inner core component edge, smoothing processing also must be made in the edge of inner core component angle steel and the corresponding acropodium of buckling-restrained parts position, has so increased construction complexity.In addition, to inner core component, constraint may cause fitting tightly because of many ripples bending deformation of kernel confining part effect decline to these buckling-restrained parts, and then affects buckling-restrained effect.
