Description
Technical field
The invention belongs to more high-rise assembleds of structural engineering field more particularly to a kind of replaceable empty stomach energy consumption section of band are high
Strong steel composite steel frame structure.
Background technique
Assembling type steel structure can realize industrialized production, effectively accelerate construction progress, reduce labor intensity, it is dirty to reduce construction
Dye, is the development trend of domestic and international future architecture.Assembling type steel structure is common in low-rise dwelling, answering in Multistory-tall building
Still in its infancy with research.Girder truss is widely used in high-rise assembled steel frame structures more at present, reason is truss
Beam can effectively increase structure design span, and cut, convenient welding, pass through convenient for equipment installation, be suitble in more high-rise dresses
With being applied in formula steel construction.
Currently, frame column breaks at node in the existing more high-rise assembling type steel structure systems using girder truss in China
It opens, stress is bad, although adding diagonal brace (its both ends is connected with girder truss, frame column respectively) by being added at node and being changed
It is kind, but diagonal brace will increase frame column by curved and influence wall arrangement.Under greater level seismic loading, truss beam end chord member
And part web member is easy to happen unstability, and structural strength and rigidity is caused to be degenerated rapidly, ductility and energy-dissipating property are bad, and rod piece loses
Steady position is not concentrated, and the economy of repairing and reinforcement and time cost are significant after shake.Therefore, the anti-of girder truss how is rationally effectively improved
Shock stability is one of the critical issue promoting girder truss and applying in more high-rise assembling type steel structures.
" seismic design provision in building code " (GB50011-2010) has mandatory item for steel used in lateral resistant member in China
Literary clear stipulaties (3.9.2 item): (1) the ratio between yield strength measured value and tensile strength measured value should not exceed 0.85；(2) steel
There should be apparent surrender step, and elongation is no less than 20%.The regulation limits the steel strength for being used for lateral resistant member
Within the scope of 345MPa, high-strength steel is limited in the application of China's building field.The Aseismic Structure System with energy consumption section is selected,
Middle energy consumption section and the big component of deformation using common iron deform, rather than the section etc. that consumes energy deform lesser position use it is high-strength
Steel are spent, if clocking requirement non-dissipative member under big shake still in elastic stage or develops part plasticity, and the section that consumes energy is then complete
Enter elastic-plastic behavior entirely to consume energy, so that it may which guarantee reaches the target provided fortification against earthquakes, also just without the steel to non-dissipative member
It is proposed excessively high plastic deformation requirement.
Summary of the invention
The purpose of the present invention is to provide a kind of more high-rise assembled high-strength steel of the replaceable empty stomach energy consumption section of band to combine steel
Frame structure, it is intended to quickly be repaired after improving the energy dissipation capacity, frame structure force-transmission mechanism and realization shake of girder truss, the structure
System can promote the application of girder truss and high-strength steel in more high-rise assembled anti-knock steel structure systems.
The invention is realized in this way a kind of more high-rise assembled steel frame structures of the replaceable empty stomach energy consumption section of band, it should
Structure includes girder truss and the frame column for being used to support the girder truss both ends；Wherein, the girder truss be divided into energy consumption section and
Non- energy consumption section；The girder truss energy consumption section is open web type arrangement；Girder truss energy consumption section both ends respectively with a non-energy consumption section one
End is removably docked, and the non-energy consumption section other end of girder truss is mounted on frame column；
The chord member and the non-energy consumption section web member of girder truss of the girder truss energy consumption section are constituted using ordinary steel；The girder truss
Chord member, the frame column of non-energy consumption section are constituted using high-strength steel.
Preferably, the bean column node between the non-energy consumption section of the girder truss and frame column is connected using ConXR node.
Preferably, the ConXR node includes cylinder inner sleeve plate, beam-ends flag, the plug and beam-ends of cylinder inner sleeve plate
The socket of flag is with girder truss rear locking beam column in place from top to bottom, then passes through high-strength bolt and fasten.
Preferably, the inside and outside cage plate of the ConXR node is constituted using high-strength steel.
Preferably, the girder truss energy consumption Duan Yufei energy consumption section is connected using extended end plate fitted bolt.
Preferably, the frame column is square steel tube section and keeps section perforation at beam-column connection.
Preferably, the chord member of the girder truss is H profile steel section, web member is back-to-back channel steel compound section, chord member and abdomen
Bar is welded by gusset plate.
More high-rise assembleds that the present invention overcomes the deficiencies of the prior art and provide a kind of replaceable empty stomach energy consumption section of band are high-strength
Steel composite steel frame structure.The application is more, and high-rise assembled steel frame structure is made of quadrate steel pipe column, girder truss, and bean column node is
ConXR connection in the ConXtechConX system that U.S. norm is recommended, frame column penetrate through node, and stress is preferable；Girder truss span centre
Setting energy consumption section, and remove web member and arranged using open web type, the section rod piece is lower using yield point, deformability is preferably general
Logical steel, when girder truss bears larger shearing, energy consumption section generates plastic deformation, dissipation energy, final chord member both ends shape first
At plastic hinge, realizes and concentrate energy consumption；The non-energy consumption section chord member of girder truss and frame column are located substantially under biggish horizontal loads
High strength steel composition can be used in elastic stage or development part plasticity, saving steel reduces dead load, reduces earthquake and makees
With；Energy consumption Duan Yufei energy consumption section girder truss is bolted using extended end plate-, is quickly repaired after realizing shake.
Compared with the prior art the shortcomings that and deficiency, the invention has the following advantages:
(1) girder truss is applied to more high-rise assembling type steel structure systems by the present invention, effectively increases design span, and cut
It cuts, convenient welding, is passed through convenient for equipment installation；
(2) replaceable energy consumption section is arranged in the present invention in girder truss, can improve the energy dissipation capacity and frame knot of girder truss
Structure force-transmission mechanism realizes the concentration damage of structure, precisely consumes energy, convenient for repairing after shake；
(3) present invention is constituted using high-strength steel and ordinary steel combination, that is, remains the excellent energy-dissipating property of common iron, again
It played high-strength hardness of steel height, saved the advantage of material, and dead load is effectively reduced, reduced geological process；
(4) present invention can push high-strength steel and girder truss to apply in more high-rise assembling type steel structures.
