Description
Technical field
The present invention relates to building structure, specifically a kind of without inner core super-high building structure.
Background technology
Frame-Shear wall is widely applied in the super highrise building of current China, this structure is made up of the rare post framework of Core Walls Structure and periphery, post is apart from being generally 8m ~ 12m, and post and Zhou Bianliang form outside framework, and outside framework by beam and floor and intercooler core tubular integrally.Function in Core Walls Structure is mainly escalator, staircase, piping shaft and fire-fighting cup, also communal bathroom etc. can be placed in Core Walls Structure if desired.
Although Frame-Shear wall exists plurality of advantages and is widely used, also come with some shortcomings, such as:
(1) Design of Connecting Beam difficulty.It is little that coupling beam in Frame-Shear wall generally has span, stressed special, and the cylindrical shell shear wall rigidity of connection is the feature such as very large again.When structure is subject to horizontal force action, in cylindrical shell, coupling beam is stressed comparatively large, for ensureing that structural safety prevents shear failure, often occurring that coupling beam calculates arrangement of reinforcement value and transfinites, bringing difficulty to Cross section Design.And in the more complicated framed-tube structure of plane (as Core Walls Structure eccentric setting), the cross section value size of a certain coupling beam affects greatly the dynamic characteristic of total sometimes, makes the cycle, and the multinomial earthquake index such as Displacement Ratio is difficult to meet code requirement.Therefore the Design of Connecting Beam in plane complicated Frame-Shear wall is often more difficult than the Design of Connecting Beam in common shear wall structure.Meanwhile, Core Walls Structure body of wall, as most important lateral resistant member, often due to the needs of door opening, hydrant and pipeline box out, makes the torsional property of structure by weakening to a certain extent.
(2) economy is poor.Core Walls Structure is the main lateral resistant member of Frame-Shear wall, require that Core Walls Structure all has larger anti-side rigidity in all directions, bear the horizontal shear of more than 80%, and outside framework is mainly used in bearing vertical load, and shares the sub-fraction horizontal shear of distributing gained by rigidity.The arm of force of the resistance to tipping moment of Core Walls Structure depth-width ratio comparatively large (compared with outside framework) is less, can only be strengthened the resistance to tipping moment of Core Walls Structure, will certainly increase steel using amount like this, increase construction cost by modes such as increase deadweight, minimizing punch.
(3) utility ratio is not good, and plane function is arranged limited.In traditional Frame-Shear wall; the design preferences of Core Walls Structure is it is considered that the lateral resisting ability of structure; next is only vertical traffic and apparatus arrangement; so just there will be core wall structure and deviation appears in Functional Design; the structure design of such as Core Walls Structure is no problem; but there is the situation of space affluence or insufficient space in the plane figure's design in Core Walls Structure, the structure design due to Core Walls Structure involves the design of whole building structure, and adjustment is got up very difficult and bothered.For avoiding the consideration occurring Core Walls Structure insufficient space and strengthen resistance to tipping moment, the section area of Core Walls Structure often designs larger, thus reduces the utility ratio of building structure.
Therefore design and a kind ofly there is better economy and the comparatively simple super-high building structure of the member designs such as coupling beam is a technical barrier urgently to be resolved hurrily.
Summary of the invention
The technical problem that the present invention solves is to provide a kind of without inner core super-high building structure, makes it have better economy, conveniently carry out structural element design, and plane figure is more flexible.

One of improve: described vertical posts is SRC post or reinforced concrete post, and described tie-beam is SRC beam, reinforced concrete beam or girder steel.In Practical Project, bearing wall and frame structure specifically adopts how many SRC post, how many reinforced concrete beams, how many SRC beam, how many reinforced concrete beams.Such as vertical posts adopts SRC post, and tie-beam also adopts SRC beam; Or part vertical posts (as corner post) adopts SRC post, all the other vertical posts adopt reinforced concrete post, and part tie-beam adopts SRC beam, and all the other tie-beams adopt; Or vertical posts all adopts reinforced concrete post, tie-beam also all adopts reinforced concrete beam.At this no longer exclusive list.
Two of improvement: the whole horizontal shears bearing described building structure of described outer framed-tube structure, or bear the horizontal shear more than 80%.
Three of improvement: the described floor of each layer comprises some brace summers and be arranged on the floor layer on this some brace summer, and described brace summer is girder steel or SRC beam, and described floor layer is reinforced concrete floor layer, cassette ceiling layer or composite floor layer etc.
Four of improvement: described floor has at least part brace summer to be connected to a described SRC post of described outer framed-tube structure and the described vertical posts of described bearing wall and frame structure, and at least also have part brace summer to be connected to a described SRC post of described outer framed-tube structure and the described tie-beam of described bearing wall and frame structure.
Five of improvement: in the vertical posts of described bearing wall and frame structure, part vertical posts is common SRC post, part vertical posts is for strengthening SRC post, in the link that the described brace summer of described floor is connected with described bearing wall and frame structure, the link be wherein connected with the reinforcement SRC post of described bearing wall and frame structure is for just to connect, and all the other links are for just to have connect or hinged.In the bearing wall and frame structure of this improvement project, common SRC post and reinforcement SRC post are relativeness, and represent that the rigidity, sectional dimension etc. of strengthening SRC post are comparatively large, common SRC post is then less.Concrete common SRC post, the size strengthening SRC post, steel content, concrete thickness, sectional dimension and shape etc. need to determine according to actual demands of engineering.
Six of improvement: described inner frame is rectangular, its four angles place is provided with vertical posts; The horizontal section of described outer framed-tube structure is roughly rectangular and post is not established in four angles, the interior recess at its four angles is provided with Three S's RC post, in four piece SRC posts nearest with this Three S's RC post, and be connected to described brace summer between two distant SRC posts of this Three S's RC post and the vertical posts at described bearing wall and frame structure respective corners place, and be also connected with at least one first stiffening girder between this brace summer described in two, be also connected with the second stiffening girder between this Three S's RC post and nearest first stiffening girder; Be respectively equipped with towards the extended structure of its adjacent SRC post with two SRC posts of the close together of this Three S's RC post, between each extended structure and the first nearest stiffening girder, be connected with the 3rd stiffening girder.

(2) relative to building structure material-saving and the economy more adopting RC component.Because SRC component is stronger than the shear resistant capacity of RC component, therefore lateral resisting ability, with weight capacity require roughly equal, and structure roughly the same when, the required steel using amount of building structure of the present invention and concrete amount, especially concrete amount are also less than the building structure adopting RC component.
(3) because the outer framed-tube structure of building structure of the present invention assume responsibility for most of horizontal shear, therefore can replace by frame construction the core wall structure that shear wall encloses formation.Traditional Frame-Shear wall, because ensureing that Core Walls Structure has certain anti-side rigidity, ensure that Core Walls Structure has certain ductility to meet the requirement of seismic design again, therefore to Core Walls Structure design itself and association member designs comparatively difficult, especially when building height exceedes specification limits requirement, when building structure is irregular, as Core Walls Structure eccentric setting, building structure center of gravity and geometric center inconsistent, the difficulty of structure design is large, and is difficult to meet building safety requirement.And the Lateral Resistant System that outer framed-tube structure of the present invention adds bearing wall and frame structure is not only reasonable more economically, the requirement of Seismic Design of Building can be met, and the structure of entirety and member designs will be simpler, can adapt to more complicated, irregular building structure, thus plane figure is more flexible.

In the present invention, term " on ", D score, "left", "right", "front", "rear", " top ", " end ", " interior ", " outward ", " in ", " vertically ", " level ", " transverse direction ", the orientation of the instruction such as " longitudinal direction " or position relationship be based on orientation shown in the drawings or position relationship.These terms are mainly in order to describe the present invention and embodiment better, and being not intended to limit indicated device, element or ingredient must have particular orientation, or carry out constructing and operating with particular orientation.
Further, above-mentioned part term represents except orientation or position relationship except may be used for, and also may be used for representing other implications, such as term " on " also may be used in some cases representing certain relations of dependence or annexation.For those of ordinary skills, these terms concrete meaning in the present invention can be understood as the case may be.
In addition, term " installation ", " setting ", " being provided with ", " connection ", " being connected " should be interpreted broadly.Such as, can be fixedly connected with, removably connect, or monolithic construction; Can be mechanical connection, or electrical connection; Can be directly be connected, or be indirectly connected by intermediary, or be connection inner between two devices, element or ingredients.For those of ordinary skills, above-mentioned term concrete meaning in the present invention can be understood as the case may be.
In addition, term " first ", " second " etc. are mainly used for distinguishing different devices, element or ingredient (concrete kind is identical with structure possibility also may be different), not for showing or imply relative importance and the quantity of indicated device, element or ingredient.Except as otherwise noted, the implication of " multiple " is two or more.
The present invention comprises without inner core super-high building structure: be arranged on the some SRC posts for the formation of outer framed-tube structure of building structure periphery and some SRC window skirt beams, be arranged on the some vertical posts for the formation of bearing wall and frame structure of building structure inside and some tie-beams, and for connecting some floor plates of outer framed-tube structure and bearing wall and frame structure.The vertical posts of this bearing wall and frame structure and tie-beam both can adopt RC component, can adopt SRC component, but considered the advantage of SRC component, preferential employing SRC component.The outer framed-tube structure of employing of the present invention adds bearing wall and frame structure and has good ductility and fireproof performance.In addition, building structure of the present invention is preferably applicable in the super highrise building of less than 250 meters, and as used in higher super highrise building, although facade can open large hole, other place still can affect facade daylighting.
For forming framed-tube structure, in horizontal plane, these SRC posts distribute along the border (as rectangle, circle etc.) of setting shape with equidistant or Unequal distance mode, and the SRC window skirt beam of each layer connects an adjacent SRC post, overall formation has tower structure---the i.e. framed-tube structure of barrel space service behaviour.The quantity of each component, as the number needs such as a SRC post, SRC window skirt beam, vertical posts, tie-beam, floor will require specifically to determine according to design of building structures.In addition, although outer framed-tube structure is similar frame construction in form, but due to the spatial behaviour that it has similar real abdomen tubular construction, its weight capacity, lateral resisting rigidity, torsional rigidity, resistance to tipping moment are completely different from the outside framework in general frame-core tube.In addition, because the periphery of building structure of the present invention defines framed-tube structure, can more effectively share horizontal shear and resistance to tipping moment, bearing wall and frame structure then only need bear horizontal shear compared with small part and resistance to tipping moment, therefore can be designed to form of structure comparatively simple, act as main tower structure with load-bearing.
SRC(Steel Reinforced Concrete, is called for short SRC) component also referred to as Steel Reinforced Concrete Members, be arrange reinforcing bar the structure of concreting around shaped steel.Existing research shows that the inside shaped steel of SRC component and external wrapping concrete form entirety, jointly stressed, and its stress performance is better than the simple superposition of these two kinds of structures.Compared with steel work, the external wrapping concrete of SRC component can prevent the cripling of steel beam column, and can improve the integral rigidity of steel beam column, significantly improves the plane torsion flexural property of steel beam column, and the intensity of steel is given full play to.In addition, external wrapping concrete considerably increases durability and the refractoriness of structure.With RC(Reinforced Concrete, being called for short RC) structure compares, owing to being configured with shaped steel, improve the bearing capacity of component, especially the SRC component of real abdomen shaped steel is adopted, its shear-carrying capacity improves a lot, and substantially improves brittleness during sheared destruction, improves the anti-seismic performance of structure.
On the one hand, building structure of the present invention is relative to traditional Frame-Shear wall material-saving and economy more.The core shell structure of traditional Frame-Shear wall due to the arm of force less, in order to reach the resistance to tipping moment of designing requirement, need the deadweight increasing core wall structure, therefore this is the not only uneconomical but also unsafe lateral resisting structure system of one.And the present invention adopts outer framed-tube structure as main lateral resisting structure, its arm of force is longer than Core Walls Structure, just can provide enough resistance to tipping moment with relatively little deadweight.Therefore building structural steel amount of the present invention, concrete amount are lower, more economically.
On the other hand, building structure of the present invention is relative to building structure material-saving and the economy more adopting RC component.Because SRC component is stronger than the shear resistant capacity of RC component, therefore in lateral resisting ability, roughly equal with weight capacity etc., and structure roughly the same when, the required steel using amount of building structure of the present invention and concrete amount, especially concrete amount are fewer than adopting the building structure of RC component.
In addition, because the outer framed-tube structure of building structure of the present invention assume responsibility for most of horizontal shear, therefore can be more weak and the frame construction being mainly used in load-bearing replaces shear wall encloses the core wall structure of formation with shear resistance.In traditional Frame-Shear wall, because ensureing that Core Walls Structure has certain anti-side rigidity, ensure that Core Walls Structure has certain ductility to meet the requirement of seismic design again, therefore to Core Walls Structure design itself and association member designs comparatively difficult, especially when building height exceedes specification limits requirement, when building structure is irregular, as Core Walls Structure eccentric setting, building structure center of gravity and geometric center inconsistent, the difficulty of structure design is large, and is difficult to meet building safety requirement.And outer framed-tube structure of the present invention adds bearing wall and frame structure, not only can meet the requirement of Seismic Design of Building, and the structure of entirety and member designs will be more simple, can adapt to more complicated, irregular building structure.
The lateral rigidity of the outer framed-tube structure of building structure of the present invention is greater than bearing wall and frame structure lateral rigidity, the horizontal shear of corresponding proportion (more) is born respectively in lateral rigidity ratio, the horizontal shear that outer framed-tube structure is born is greater than the horizontal shear that bearing wall and frame structure is born, namely outer framed-tube structure needs the horizontal shear born more than 50%, in certain embodiments, outer framed-tube structure then assume responsibility for more than 60%, 70%, the even horizontal shear of 80%.Then just contrary in traditional Frame-Shear wall, its Core Walls Structure assume responsibility for most horizontal shear, and outside framework only bears very little a part of shearing, and this is a kind of uneconomic lateral resisting structure system.Building structure of the present invention can provide larger resistance to tipping moment larger with less deadweight, therefore material-saving, economy more.
Further, in order to form the tubular construction of frame cartridge form, realize the spatial behaviour of similar real abdomen cylindrical shell, the condition that outer framed-tube structure demand fulfillment is certain.Such as post is apart from being greater than 4m, and the long limit of column section should be arranged along barrel direction, can adopt T-shaped cross section if desired; Hole area should not be greater than 60% of wall area, and the ratio of hole depth-width ratio and floor height and post distance is close etc.But due to compared with RC component, SRC component has stronger vertical bearing capacity and shear resistance, therefore when roughly the same mechanical property requirements, the section area of SRC component will be less than the section area of RC component.Therefore the present invention's outer framed-tube structure of adopting SRC post, beam to be formed, can arrange more Large Column Spacing and the rate that punches more greatly, avoid original framed-tube structure because post distance and the rate that punches too small and affect the problem of the view visual field and daylighting.The post of the one SRC post of outer framed-tube structure of the present invention is apart from being set to be greater than 4m and be less than 6m, and the deck-molding of the SRC window skirt beam of outer framed-tube structure is 0.8m to 1.3m, and preferred deck-molding is 0.9 to 1.2m.The rate of punching of outer framed-tube structure is 40% to 60%, and the rate that preferably punches scope is 55% to 60%.Simultaneously due to the fireproof performance of SRC component and endurance quality than RC component and steel beam column better, the framed-tube structure therefore adopting SRC component to be formed also has better fireproof performance.
Below in conjunction with embodiment, building structure of the present invention is described further.
embodiment one.
As shown in Figures 1 to 3, comprising without inner core super-high building structure of the present embodiment: the outer framed-tube structure be combined to form by a SRC post and SRC window skirt beam 22, the bearing wall and frame structure be combined to form by vertical posts 11 and tie-beam 12, and for connecting some floor plates of outer framed-tube structure and bearing wall and frame structure.This bearing wall and frame structure eccentric setting, its geometric center departs from the geometric center of housing cylinder, and the geometric center of bearing wall and frame structure is positioned at the region, northwest of outer framed-tube structure as shown in Figure 3.If adopt traditional Frame-Shear wall, so design of inner core cylinder, the Design of Connecting Beam between outside framework and inner core cylinder are by quite complicated, and design difficulty is very large.After but the housing cylinder using the present embodiment instead adds the structure of inner frame, because the bearing wall and frame structure of inside is mainly used in load-bearing, only bear sub-fraction horizontal shear, therefore the Design of Connecting Beam between outer framed-tube structure and bearing wall and frame structure, and the design of bearing wall and frame structure itself will be quite simple, make the plane figure of building structure more flexible.
As shown in Figure 3, the outer framed-tube structure rectangular in cross-section of the present embodiment, is in the consideration of outward appearance and folding corner region view, and post is not established in its four angles.Respectively there are 12 posts in the east of outer framed-tube structure, southern side apart from the SRC post 21 for 4.2m, and respectively there is a SRC post 21 of 8 Unequal distance posts in west, north side.Wherein, the post of outer framed-tube structure west side the 1st to the 3rd SRC post 21 in (from north orientation south to) is from top to bottom apart from being 4.2m, 3rd, the post of a 4th SRC post 21 expands as 3 across (i.e. 12.6m) apart from because facade view requires, 4th, the post of a 5th SRC post 21 is apart from expanding as 2 across (i.e. 8.4m), and the post distance of the 5th to a 8th SRC post 21 is normal 4.2m.The one SRC post 21 of (from West to East the aspect) from left to right of outer framed-tube structure north side is arranged and is arranged similar with a SRC post 21 in west side.Be understandable that, the shape of housing cylinder, inside casing cylinder also can be arranged to circle etc.
