Description

A kind of half waveform buckling restrained brace structure
Technical field
It the utility model is related to a kind of buckling restrained brace for being used to reduce engineering structure seismic response, particularly one kind half Waveform buckling restrained brace structure, belongs to field of civil engineering.
Background technology
Before the 1990s, traditional structural seismic method is by agent structure local yielding dissipation seismic energy Amount, such as beam hinge, this energy dissipation mode causes main structure body to destroy, seriously add repair after shake difficulty and into This, repairs after being unfavorable for the shake of structure;From after Japanese Osaka-Kobe earthquake and the ridge earthquake of U.S. north, buckling restrained brace is as a kind of property The superior energy-dissipating and shock-absorbing component of energy, in Japan, U.S. etc., the developed countries of more shakes have obtained quick popularization and application, in China Research is also at developing stage.Buckling restrained brace becomes in core component outer wrapping constraint component to limit the bending of core component Shape, dissipation seismic energy is surrendered by core component tension and compression, equivalent to common central supported under small shake effect, carried to structure For enough lateral rigidities, under the effect of medium and larger earthquake equivalent to metal damper dissipation energy, so both improve The ductility of structure has given full play to the power consumption effect of support again, the agent structure will not be destroyed or is destroyed under geological process It is smaller, it is a kind of ideal energy dissipation mode.
At present, the inner core member section in buckling restrained brace mainly with in-line, cross and it is I-shaped based on, this kind The buckling restrained brace of structural form has preferable Hysteresis Behavior in resistance to compression, but has that ductility is poor, tensile property is insufficient The problem of, hysteretic energy hydraulic performance decline is very fast under geological process so that buckling restrained brace works under the conditions of multiple aftershock Hydraulic performance decline amplitude is larger.
Utility model content
The utility model technical issues that need to address are to be directed to above-mentioned the deficiencies in the prior art, and provide a kind of making side Just, half high waveform buckling restrained brace structure of reliability.
In order to solve the above technical problems, the technical solution adopted in the utility model is:
A kind of half waveform buckling restrained brace structure, including dissipative member, two confining parts and anchorage element, the consumption Energy component is wavy shaped configuration sheet material, and the confining part is the sheet material of rectangular configuration, and two confining parts are separately positioned on consumption Above and below energy component, positioned at dissipative member and the marginal position of confining part, at least provided with four anchorage elements, anchor Gu component runs through two confining parts and dissipative member.
As further preferred scheme, the wavy shaped configuration of the dissipative member is set upward.
As further preferred scheme, the both ends of the dissipative member are additionally provided with stiffener.
As further preferred scheme, the thickness of the dissipative member is 8mm, and the thickness of the confining part is 12mm。
As further preferred scheme, a strata chlorine tetrafluoroethene layer, its thickness are laid in the surface of the confining part For 1mm.
As further preferred scheme, the crest of the wave structure of the dissipative member and the spacing of top confining part For 2mm, the spacing of dissipative member and lower section confining part is 2mm.
Beneficial effect
Compared with prior art, a kind of half waveform buckling restrained brace structure of the present utility model, dissipative member and constraint Component is assembled using high-strength bolt, is easy to disassemble, and the damage situations of interior core unit can be checked after earthquake, according to impaired journey Degree alternative is changed, convenient and swift, is economized on resources, compared with common buckling restrained brace, interior core unit uses half-wave Shape construction can avoid the big flexible and stress raisers of core, improve the tension and compression deformation ability repeatedly of core, have good Good ductility.
