Description

High level and super highrise building concrete filled steel tube zeugopodium formula truss combination construction
Technical field
The invention belongs to the Structural Engineering field in the civil engineering, particularly a kind of high level and super highrise building concrete filled steel tube zeugopodium formula truss combination construction.
Background technology
Built in China or at the forefront in the world at high level of building or super highrise building number of bits according to incompletely statistics, is ended 2011 at present, and having built up perhaps, the mansion of calculated height above 300 meters reached 15.The design of these high levels or super highrise building and building course have also played huge promotion and innovation effect to the development of Building technology and construction theory.
In existing high level and super-high building structure system; Along with the structural system type is different, and because the increase of height, the member section size has the trend of increase; In the huge trussed construction like Hong Kong Bank of China Tower; The sectional dimension of the solid corner post of steel concrete is 4.8 meters * 4.1 meters, and the steel truss sectional dimension in Tokyo town hall No. 1 building of mansion is 6.4 meters * 6.4 meters, and the huge column cross-section size of the steel reinforced concrete at center, Shanghai is 3.7 meters * 5.3 meters.On this yardstick, utilize solid concrete member or real abdomen formula steel member just to relate to, and the scantling size still is restricted, is unfavorable for further improving structure height such as problems such as casting of concrete in mass and the processing of steel work slab.
Concrete filled steel tube is the structure that fill concrete forms in steel pipe.When stressed, the outer steel pipe of concrete filled steel tube has formed effective constraint to core concrete common.Owing to made full use of steel tension and the measuring body material behavior of concrete, encased structures has advantages such as bearing capacity height, rigidity are big than the big or small steel work of same cross-sectional or concrete structure.Characteristics such as in addition, encased structures also has the saving template, and speed of application is fast, and antidetonation, fire resistance are good therefore just increasingly are applied in high level and superelevation layer structure.Characteristics such as the steel pipe concrete truss structure of development utilizes concrete filled steel tube as chord member on this basis, and empty steel tubular structure has the cross section and carries out as web member, and rigidity is big, and non-deformability is strong.Mostly the web member of existing trussed construction is sky steel pipe or steel work, destroys to be mostly that web member cripling or weld seam destroy, and the strength capabilities of chord member can not be not fully exerted.Therefore the higher demand that presses for that carry out in a kind of cross section, intensity high, rigidity is big, construction is convenient, anti-seismic performance good, adapts to high level and superelevation layer Structural Engineering aspect from the structural element and the corresponding structure form of heavy and light.
Summary of the invention
The objective of the invention is to adapt to high-rise and super-high building structure higher requirement aspect function of use and structure height for following design high-rise and the super-high building structure system provides a solution.
The object of the invention is realized through following technical proposals; Constitute by concrete filled steel tube zeugopodium formula girder truss, concrete filled steel tube zeugopodium formula truss support and concrete filled steel tube zeugopodium formula truss leg; Some concrete filled steel tube zeugopodium formula girder trusses and some concrete filled steel tube zeugopodium formula truss leg cross arrangements constitute the quadrangle array, and a concrete filled steel tube zeugopodium formula truss support that angle point is connected with quadrangle is set in each quadrangle;
Described concrete filled steel tube zeugopodium formula girder truss, concrete filled steel tube zeugopodium formula truss support and concrete filled steel tube zeugopodium formula truss leg are concrete filled steel tube zeugopodium formula truss; Concrete filled steel tube zeugopodium formula truss perhaps is welded to connect through flange along its length by 2~10 concrete filled steel tube chord members and constitutes, and perhaps is welded to connect with flange through the concrete filled steel tube web member between the different concrete filled steel tube chord members.
The cross section of said concrete filled steel tube chord member is rectangle, circle or oval.
The cross section of said concrete filled steel tube web member is rectangle, circle or oval.
The outer tube material of said concrete filled steel tube chord member and concrete filled steel tube web member is common iron, high-strength steel or stainless steel.
The core concrete material of said concrete filled steel tube chord member and concrete filled steel tube web member is ordinary concrete or high-strength concrete.
The limb number of the concrete filled steel tube chord member of said single concrete filled steel tube zeugopodium formula girder truss, concrete filled steel tube zeugopodium formula truss support or concrete filled steel tube zeugopodium formula truss leg is 2~8 limbs.
The present invention can do following improvement:
Concrete filled steel tube zeugopodium formula truss combination construction can combined with steel reinforced concrete shear wall and steel concrete core tube, forms outside framework and adopts concrete filled steel tube zeugopodium truss, the inner combination construction that adopts reinforced concrete shear wall or core tube.
The periphery of concrete filled steel tube zeugopodium trussmember own can the combined with steel reinforced concrete member, buries the steel concrete wall member of concrete filled steel tube zeugopodium truss in the formation, to obtain bigger rigidity and bearing capacity.
Beneficial effect of the present invention is:
(1) this structure Path of Force Transfer is clear and definite, and rigidity is big, and good stability is applicable to the building of high altitude and span more.
(2) the zeugopodium trussmember with effective distribution of material around, carry out in the cross section, chord member and web member all adopt concrete filled steel tube, rigidity is big, bearing capacity is high.Owing to adopt trussed construction, compare with common solid component and under same section area situation, avoided ultra-large volume concrete work such as to build, also can more effectively utilize the performance of material.Because zeugopodium has been filled concrete, has effectively avoided the steel pipe flexing, has improved rigidity, can reduce or partly substitute the application of shear wall.
(3) antidetonation, wind resistance, fire resistance are good.Because chord member inside is fill concrete also, higher than conventional steel concrete truss supporting capacity, rigidity is bigger, effectively improves the node region performance.Bigger than conventional steel structural damping, wind resistance is good, and better fire resistance is arranged.
(4) space availability ratio is high.The inner space of girder truss and truss leg can be utilized effectively, such as escalator etc. is set.Floor system can directly be built on main frame, also can adopt suspension floor slab structure etc., and layout can be versatile and flexible.
(5) the structural system deadweight is lighter, and damping ratio is bigger.
(6) speed of application is fast.The agent structure basic building block can be prefabricated, on-the-spot do not need assembling reinforcement basically when building main structure and build work such as concrete blinding.
