Abstract
The utility model relates to a buckling restrained brace type ductility truss frame structure, and belongs to the field of building trades. The buckling restrained brace type ductility truss frame structure comprises at least two frame columns, wherein at least two layers of truss girders are arranged between adjacent frame columns; each truss girder comprises a top chord, a lower chord and a diagonal web member; and at least one layer of truss girders comprises a truss session which is formed by a section of top chord, a section of lower chord corresponding to the top chord, and a buckling restrained brace between the section of top chord and the section of lower chord. Compared with a normal truss frame structure, the buckling restrained brace type ductility truss frame structure has a good anti-seismic property. When horizontal earthquake action reaches to a certain degree, two ends of a chord member of a buckling restrained brace type energy dissipation session can form a plastic hinge, so anti-seismic power-wasting purpose is achieved. Truss rod pieces and the frame columns besides the buckling restrained brace type energy dissipation session still keep an elastic work condition, so safety of the whole structure is ensured.
Description
Technical field
The utility model relates to the earthquake-resistant building structure type in a kind of building trade field, specifically a kind of purlin mount structure that utilizes buckling restrained brace to consume energy.
Background technology
The purlin mount structure refers to replace with girder truss a kind of combining structure of real abdomen formula girder steel in the frame construction, is mainly used in Long-span Multi-storey Frame degree building.But the truss ductility in the mount structure of common purlin is relatively poor, easily because whole destruction occurs the rod member unstability, therefore should not be used for providing fortification against earthquakes the area under geological process.
Truss in the mount structure of common purlin is carried out the antidetonation transformation, improve its ductility, improve the anti-seismic performance of purlin mount structure, have important practical significance.The buckling restrained brace formula ductility purlin mount structure that the utility model proposes is exactly wherein a kind of, and this class formation can be applied to provide fortification against earthquakes in the Long-span Multi-storey Frame degree building in area.
The utility model content
The utility model is not enough for the anti-seismic performance of common purlin mount structure, and a kind of ductility purlin mount structure is provided, and can significantly improve ductility and the energy dissipation ability of purlin mount structure, has good economic benefit and social benefit.
For achieving the above object, the utility model adopts following technical proposals:
A kind of buckling restrained brace formula ductility purlin mount structure, it comprises at least two frame columns, be provided with at least two-tier truss beam between the adjacent frame trestle, described girder truss mainly is comprised of upper chord, lower chord and diagonal web member, at least one deck girder truss comprises a truss section, and this truss section is comprised of one section upper chord, one section lower chord corresponding with this section upper chord and the buckling restrained brace between this section upper chord and this section lower chord, the oblique setting of buckling restrained brace, and two ends are hinged with upper chord and lower chord respectively about it.
All be provided with described truss section on every layer of girder truss.
Described truss section is positioned at the central authorities of girder truss span.
Described truss section middle part adopts a buckling restrained brace as the truss internode of diagonal web member, its top-bottom chord two ends are hinged, form buckling restrained brace formula energy dissipating section, buckling restrained brace formula energy dissipating section is positioned at the span central authorities of girder truss, and the design bearing capacity of buckling restrained brace is determined according to the seismic fortification intensity of building their location.
The beneficial effect that the utility model produces:
1. under horizontal earthquake action, when the earthquake effect acquired a certain degree, buckling restrained brace took the lead in surrendering, thereby had increased the ductility of structure, had realized the purpose of energy dissipation.
2. after the buckling restrained brace surrender, all the other truss members and frame column still keep elastic state, thereby guarantee integrally-built safety, prevent from caving in and toppling.
Description of drawings
Fig. 1 is that buckling restrained brace formula ductility purlin mount structure forms schematic diagram.
Wherein: 1. frame column; 2. girder truss; 3. buckling restrained brace formula energy dissipating section; 4. buckling restrained brace.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, a kind of buckling restrained brace formula ductility purlin mount structure, it comprises three frame columns 1, be provided with three layers of girder truss 2 between the adjacent frame trestle 1, described girder truss 2 mainly is comprised of upper chord, lower chord and diagonal web member, the central authorities of every layer of girder truss 2 span are all with a buckling restrained brace formula energy dissipating section 3, this buckling restrained brace formula energy dissipating section 3 is a truss section, and this truss section is comprised of one section upper chord, one section lower chord corresponding with this section upper chord and the buckling restrained brace 4 between this section upper chord and this section lower chord.Buckling restrained brace 4 oblique settings, and the top-bottom chord two ends of buckling restrained brace 4 itself are hinged with this section upper chord and this section lower chord respectively, and pin joint is in the junction of adjacent diagonal web member, straight web member and upper chord or lower chord.
When carrying out structure design, the design bearing capacity of buckling restrained brace 4 determines that according to the seismic fortification intensity of building their location all the other members can carry out according to a conventional method internal force and calculate and analyze.
Compare with common purlin mount structure, buckling restrained brace formula ductility purlin mount structure has good anti-seismic performance, when horizontal earthquake action acquires a certain degree, the chord member two ends of buckling restrained brace formula energy dissipating section can form plastic hinge, thereby realize the purpose of energy dissipation, and the truss member outside the buckling restrained brace formula energy dissipating section and frame column still keep elastic state, have guaranteed integrally-built safety.
Although above-mentionedly by reference to the accompanying drawings the specific embodiment of the present utility model is described; but be not the restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
