Description
Technical field
The utility model belongs to the how high of structural engineering field more particularly to a kind of replaceable X-shaped of band weak web member energy consumption section
Layer assembled 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.
