Description
Technical field
The present invention relates to building structure, specifically a kind of without the inner core super-high building structure.
Background technology
Widely apply framework-core wall structure in the super highrise building of China at present, this structure is by Core Walls Structure and peripheral rare post system framework, post is apart from being generally 8m～12m, post and Zhou Bianliang formation outside framework, and outside framework forms integral body by beam and floor and intercooler core cylinder.Function in the Core Walls Structure is mainly escalator, staircase, piping shaft and fire-fighting cup, also communal bathroom etc. can be placed in the Core Walls Structure in case of necessity.
Although there is plurality of advantages in framework-core wall structure and is widely used, also come with some shortcomings, for example:
(1) Design of Connecting Beam difficulty.It is little that coupling beam in framework-core wall structure generally has span, stressed special, and the cylindrical shell shear wall rigidity of connection is the characteristics such as very large again.When structure was subject to horizontal force action, coupling beam was stressed larger in the cylindrical shell, and for ensureing that structural safety prevents shear failure, coupling beam calculating arrangement of reinforcement value often occurring transfinites, and brings difficulty to Cross section Design.And in the complicated framed-tube structure in plane (such as the 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 satisfy code requirement.Therefore the Design of Connecting Beam in plane complicated framework-core wall structure is often more difficult than the Design of Connecting Beam in the common shear wall structure.Simultaneously, the Core Walls Structure body of wall is as most important lateral resistant member, often because the needs of door opening, hydrant and pipeline box out, makes the torsional property of structure be subject to a certain degree weakening.
(2) economy is relatively poor.Core Walls Structure is the main lateral resistant member of framework-core wall structure, require Core Walls Structure on all directions, all to have larger anti-side rigidity, bear the horizontal shear 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 overturning or slip resistance analysis moment of Core Walls Structure depth-width ratio large (comparing with outside framework) is less, can only will certainly increase like this steel using amount by increasing deadweight, reducing the overturning or slip resistance analysis moment that the mode such as punch strengthen Core Walls Structure, increases construction cost.
(3) utility ratio is not good, and plane function is arranged limited.In traditional framework-core wall structure; what the design preferences of Core Walls Structure was considered is the lateral resisting ability of structure; next is only vertical traffic and apparatus arrangement; will core wall structure appear and deviation appears in Functional Design like this; for example the structure design of Core Walls Structure is no problem; but the situation of space affluence or insufficient space appears in the design of the plane figure in the Core Walls Structure, because the structure design of Core Walls Structure involves the design of whole building structure, adjusts very difficult and trouble.Be the consideration of avoiding the Core Walls Structure insufficient space occurring and strengthening overturning or slip resistance analysis moment, the section area of Core Walls Structure tends to design greatlyr, has reduced thus the utility ratio of building structure.
Therefore design that a kind of to have the comparatively simple super-high building structure of the member designs such as better economy and coupling beam be a technical barrier that needs to be resolved hurrily.
Summary of the invention
The technical problem that the present invention solves provides a kind of without the inner core super-high building structure, makes it have better economy, conveniently carry out the structural element design, and plane figure is more flexible.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of without the inner core super-high building structure, it comprises: the some SRC posts that are used to form outer framed-tube structure and the some SRC window skirt beams that are arranged on the building structure periphery; Be arranged on the some vertical posts that are used to form bearing wall and frame structure and some tie-beams of building structure inside; And, for the some floor plates that connect described outer framed-tube structure and described bearing wall and frame structure.
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 posts, how many reinforced concrete beams, how many SRC beams, how many reinforced concrete beams.For example vertical posts adopts the SRC post, and tie-beam also adopts the SRC beam; Perhaps, part vertical posts (such as corner post) adopts the SRC post, and all the other vertical posts adopt reinforced concrete post, and the part tie-beam adopts the SRC beam, and all the other tie-beams adopt; Or vertical posts all adopts reinforced concrete post, and tie-beam also all adopts reinforced concrete beam.At this exclusive list no longer.
Two of improvement: whole horizontal shears of bearing described building structure of described outer framed-tube structure, or bear and surpass 80% horizontal shear.
Three of improvement: the described floor of each layer comprises some brace summers and the floor layer that is arranged on these some brace summers, 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 the part brace summer to be connected in a described SRC post of described outer framed-tube structure and the described vertical posts of described bearing wall and frame structure, and also has at least the part brace summer to be connected in 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, the part vertical posts is common SRC post, the part vertical posts is for strengthening the SRC post, in the described brace summer of described floor and the link that described bearing wall and frame structure is connected, the link that wherein is connected with the reinforcement SRC post of described bearing wall and frame structure is for rigidly connecting, and all the other links are for rigidly connecting or hinged.In the bearing wall and frame structure of this improvement project, common SRC post and reinforcement SRC post are relativeness, and the rigidity of expression reinforcement SRC post, sectional dimension etc. are larger, and common SRC post is then less.Size, steel content, concrete thickness, sectional dimension and the shape etc. of concrete common SRC post, reinforcement SRC post need to be determined according to actual demands of engineering.
Six of improvement: described inner frame is rectangular, and its place, four angles is provided with vertical posts; Post is not established in the horizontal section of described outer framed-tube structure roughly rectangular and four angles, the interior recess at its four angles is provided with Three S's RC post, with four nearest SRC posts of this Three S's RC post in, and be connected with respectively 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 also be connected with at least one the first stiffening girder between this two described brace summer, also be connected with the second stiffening girder between this Three S's RC post and nearest first stiffening girder; Be respectively equipped with extended structure towards its adjacent SRC post with two SRC posts of the close together of this Three S's RC post, be connected with the 3rd stiffening girder between each extended structure and nearest the first stiffening girder.
Seven of improvement: the post distance of a described SRC post of described outer framed-tube structure is greater than 4m and less than 6m, and the deck-molding of the described SRC window skirt beam of described outer framed-tube structure is 0.8m to 1.3m, and the rate of punching of described outer framed-tube structure is 40% to 65%.

The beneficial effect of technical scheme that compared with prior art, the present invention adopts is as follows:
(1) with respect to traditional framework-core wall structure more material-saving and economy.The core shell structure of traditional framework-core wall structure in order to reach the overturning or slip resistance analysis moment of designing requirement, need to increase the deadweight of core wall structure, so this is a kind of not only uneconomical but also unsafe lateral resisting structure system because the arm of force is less.And the present invention adopts outer framed-tube structure as main lateral resisting structure, and its arm of force is longer than Core Walls Structure, just can provide enough overturning or slip resistance analysis moment with the deadweight of less.Therefore building structural steel amount of the present invention, concrete amount are lower, more economically.
(2) with respect to the building structure of adopting the RC member more material-saving and economy.Because the SRC member is stronger than the shear resistant capacity of RC member, therefore in the lateral resisting ability, require about equally with weight capacity, and in the roughly the same situation of structure, required steel using amount and concrete amount, the especially concrete amount of building structure of the present invention is also less than the building structure of adopting the RC member.
(3) because the outer framed-tube structure of building structure of the present invention has been born most of horizontal shear, therefore can replace the core wall structure that shear wall encloses formation with frame construction.Traditional framework-core wall structure, because guaranteeing that Core Walls Structure has certain anti-side rigidity, guarantee that again Core Walls Structure has certain ductility to satisfy the requirement of seismic design, therefore comparatively difficult to Core Walls Structure self design and related member designs, especially work as building height and surpass the specification limits requirement, when building structure is irregular, such as the Core Walls Structure eccentric setting, building structure center of gravity and geometric center are inconsistent, and the difficulty of structure design is large, and are difficult to satisfy the building safety requirement.And that outer framed-tube structure of the present invention adds the Lateral Resistant System of bearing wall and frame structure is not only reasonable more economically, can satisfy the requirement of Seismic Design of Building, and whole structure and member designs will be simpler, can adapt to more complicated, irregular building structure, thereby plane figure is more flexible.

In the present invention, term " on ", D score, " left side ", " right side ", 'fornt', 'back', " top ", " end ", " interior ", " outward ", " in ", orientation or the position relationship of the indications such as " vertically ", " level ", " laterally ", " vertically " be based on orientation shown in the drawings or position relationship.These terms mainly are in order to describe better the present invention and embodiment, to be not must have particular orientation be used to limiting indicated device, element or ingredient, or to construct and operate with particular orientation.
And above-mentioned part term also may be used for other implications of expression except can being used for expression orientation or position relationship, for example term " on " also may be used for certain relations of dependence of expression or annexation in some cases.For those of ordinary skills, can understand as the case may be these terms concrete meaning in the present invention.
In addition, term " installation ", " setting ", " being provided with ", " connection ", " linking to each other " should be done broad understanding.For example, can be to be fixedly connected with, removably connect, or monolithic construction; Can be mechanical connection, or be electrically connected; Can be directly to link to each other, or indirectly link to each other by intermediary, or be connection inner between two devices, element or the ingredients.For those of ordinary skills, can understand as the case may be above-mentioned term concrete meaning in the present invention.
In addition, term " first ", " second " etc. mainly are be used to distinguishing different devices, element or ingredient (concrete kind is identical with the structure possibility also may be different), are not be used to the relative importance and the quantity that show or hint indicated device, element or ingredient.Except as otherwise noted, the implication of " a plurality of " is two or more.
The present invention comprises without the inner core super-high building structure: the some SRC posts that are used to form outer framed-tube structure and the some SRC window skirt beams that are arranged on the building structure periphery, be arranged on the some vertical posts that are used to form bearing wall and frame structure and some tie-beams of building structure inside, and the some floor plates that are used for connecting 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 the RC member, can adopt the SRC member, but considered the advantage of SRC member, preferentially adopted the SRC member.The outer framed-tube structure of employing of the present invention adds bearing wall and frame structure and has preferably ductility and fireproof performance.In addition, building structure of the present invention preferably is applicable in the super highrise building below 250 meters, and as using in higher super highrise building, although facade can be opened large hole, other place still can affect facade daylighting.
For forming framed-tube structure, in horizontal plane, these SRC posts along the border (such as rectangle, circle etc.) of setting shape with equidistantly or equidistantly mode distribute, and the SRC window skirt beam of each layer connects an adjacent SRC post, the whole tower structure with barrel space service behaviour that forms---be framed-tube structure.The quantity of each member will require specifically to determine according to design of building structures such as number needs such as a SRC post, SRC window skirt beam, vertical posts, tie-beam, floors.In addition, although outer framed-tube structure is similar frame construction in form, but because it has the spatial behaviour of similar real abdomen tubular construction, its weight capacity, lateral resisting rigidity, torsional rigidity, overturning or slip resistance analysis moment are fully different from the outside framework in general framework-Core Walls Structure.In addition, because the periphery of building structure of the present invention has formed framed-tube structure, more effective cost share responsibility horizontal shear and overturning or slip resistance analysis moment, bearing wall and frame structure then only need be born horizontal shear and the overturning or slip resistance analysis moment than small part, 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) member is also referred to as Steel Reinforced Concrete Members, is in the arranged around reinforcing bar of shaped steel and the structure of concreting.The inside shaped steel of the existing SRC of studies show that member and external wrapping concrete form integral body, jointly stressed, and its stress performance is better than the simple superposition of these two kinds of structures.Compare with steel work, the external wrapping concrete of SRC member can prevent the cripling of steel member, and can improve the integral rigidity of steel member, significantly improves the plane torsion flexural property of steel member, and the intensity of steel is given full play to.In addition, external wrapping concrete has increased durability and the refractoriness of structure greatly.With RC(Reinforced Concrete, abbreviation RC) structure is compared, owing to disposed shaped steel, improved the bearing capacity of member, especially adopt the SRC member of real abdomen shaped steel, its shear-carrying capacity improves a lot, and the brittleness when greatly having improved sheared destruction has improved the anti-seismic performance of structure.
On the one hand, building structure of the present invention is with respect to traditional framework-core wall structure more material-saving and economy.The core shell structure of traditional framework-core wall structure in order to reach the overturning or slip resistance analysis moment of designing requirement, need to increase the deadweight of core wall structure, so this is a kind of not only uneconomical but also unsafe lateral resisting structure system because the arm of force is less.And the present invention adopts outer framed-tube structure as main lateral resisting structure, and its arm of force is longer than Core Walls Structure, just can provide enough overturning or slip resistance analysis moment with the deadweight of less.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 with respect to the building structure of adopting the RC member more material-saving and economy.Because the SRC member is stronger than the shear resistant capacity of RC member, therefore the lateral resisting ability, with weight capacity etc. about equally, and in the roughly the same situation of structure, required steel using amount and concrete amount, the especially concrete amount of building structure of the present invention lacks than the building structure of adopting the RC member.
In addition, because the outer framed-tube structure of building structure of the present invention has been born most of horizontal shear, frame construction that is therefore can be with shear resistance weak and that be mainly used in load-bearing replaces the core wall structure that shear wall encloses formation.In traditional framework-core wall structure, because guaranteeing that Core Walls Structure has certain anti-side rigidity, guarantee that again Core Walls Structure has certain ductility to satisfy the requirement of seismic design, therefore comparatively difficult to Core Walls Structure self design and related member designs, especially work as building height and surpass the specification limits requirement, when building structure is irregular, such as the Core Walls Structure eccentric setting, building structure center of gravity and geometric center are inconsistent, and the difficulty of structure design is large, and are difficult to satisfy the building safety requirement.And outer framed-tube structure of the present invention adds bearing wall and frame structure, not only can satisfy the requirement of Seismic Design of Building, and whole structure and member designs will be simpler, 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 the bearing wall and frame structure lateral rigidity, bear respectively corresponding proportion (manys') horizontal shear in the lateral rigidity ratio, the horizontal shear that the horizontal shear that outer framed-tube structure is born is born greater than bearing wall and frame structure, namely outer framed-tube structure need to be born and surpass 50% horizontal shear, in certain embodiments, outer framed-tube structure has then been born and has been surpassed 60%, 70%, even 80% horizontal shear.Then just opposite in traditional framework-core wall structure, its Core Walls Structure has been born most horizontal shears, and outside framework is only born 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 with less deadweight larger overturning or slip resistance analysis moment larger, therefore more material-saving, economy.
Further, in order to form the tubular construction of frame cartridge form, realize the spatial behaviour of similar real abdomen cylindrical shell, outer framed-tube structure need to meet some requirements.For example the post distance should not be greater than 4m, and the long limit of column section should be arranged along the barrel direction, can adopt T-shaped cross section in case of necessity; The hole area should not be greater than 60% of metope area, and the ratio of hole depth-width ratio and floor height and post distance is close etc.But owing to compare with the RC member, the SRC member has stronger vertical bearing capacity and shear resistance, and therefore in the situation of roughly the same mechanical property requirements, the section area of SRC member will be less than the section area of RC member.Therefore the present invention adopts the outer framed-tube structure that SRC post, beam form, and more Large Column Spacing and the larger rate that punches can be set, and avoids original framed-tube structure because of post distance and the too small problem that affects the view visual field and daylighting of rate that punches.The post of the one SRC post of outer framed-tube structure of the present invention is apart from can being set to greater than 4m and 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%.Because fireproof performance and the endurance quality of SRC member are better than RC member and steel member, the framed-tube structure that therefore adopts the SRC member to form also has better fireproof performance simultaneously.
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 the inner core super-high building structure of present embodiment: the outer framed-tube structure that is combined to form by a SRC post and SRC window skirt beam 22, the bearing wall and frame structure that is combined to form by vertical posts 11 and tie-beam 12, and the some floor plates that are used for connecting 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 zone, northwest of outer framed-tube structure as shown in Figure 3.If adopt traditional framework-core wall structure, the Design of Connecting Beam between so design of inner core cylinder, outside framework and the inner core cylinder is with very complex, and design difficulty is very large.But the housing cylinder of using present embodiment instead adds after the structure of inner frame, because inner bearing wall and frame structure is mainly used in load-bearing, only bear the sub-fraction horizontal shear, so Design of Connecting Beam between outer framed-tube structure and the bearing wall and frame structure, and the design of bearing wall and frame structure itself will be quite simple, so that the plane figure of building structure is more flexible.
As shown in Figure 3, the outer framed-tube structure cross section of present embodiment is rectangular, is in the consideration of outward appearance and folding corner region view, and post is not established at its four angles.Respectively there are 12 posts in the east of outer framed-tube structure, southern side apart from being the SRC post 21 of 4.2m, and respectively there are 8 not SRC posts 21 of equidistant post west, north side.Wherein, outer framed-tube structure west side from top to bottom the post of the 1st to the 3rd a SRC post 21 in (from north orientation south to) apart from being 4.2m, 3rd, the post of the 4th a SRC post 21 is striden (being 12.6m) apart from requiring to expand as 3 because of the facade view, 4th, the post of the 5th a SRC post 21 is striden (being 8.4m) apart from expanding as 2, and the post distance of the 5th to the 8th a SRC post 21 is normal 4.2m.The one SRC post 21 of from left to right (aspect from West to East) 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.
As shown in Figure 3, the horizontal section of the bearing wall and frame structure of present embodiment is rectangle, and the vertical posts 11 at its four angles is for strengthening the SRC post, and all the other are common SRC post.The vertical posts 11 of bearing wall and frame structure is arranged symmetrically, and for its either side, the centre is provided with the common SRC post of two vertical posts 11(that is spaced apart 4.2m), the vertical posts 11(in these corresponding bights of two SRC posts distance strengthens the SRC post) spacing is two to stride, i.e. 8.4m.The SRC post at place, four angles of bearing wall and frame structure can adopt the L-type post.
Each floor plate of present embodiment comprises some brace summers 31 and the floor layer that is arranged on these some brace summers 31.Brace summer 31 can adopt girder steel, SRC beam or other supporting members, and floor layer can adopt the reinforced concrete floor layer.Floor for each floor, it has at least part brace summer 31 to be connected in a SRC post 21 of outer framed-tube structure and the vertical posts 11 of bearing wall and frame structure, and also have at least part brace summer 31 to be connected in a SRC post 21 of outer framed-tube structure and the tie-beam 12 of bearing wall and frame structure, part can also be set in addition to be connected between the brace summer 31, neither be connected the brace summer 31 that also is not connected with tie-beam 12 with vertical posts 11.Traditional framework-core wall structure outside framework can only be overlapped on the reinforced concrete post of Core Walls Structure at an end that is connected Core Walls Structure with coupling beam between the inner core cylinder, and can not directly be overlapped on the shear wall of Core Walls Structure or on the Core Walls Structure inner beam.And bearing wall and frame structure of the present invention is mainly born vertical load, therefore part coupling beam (brace summer 31) directly can be overlapped on the tie-beam 12 of bearing wall and frame structure.
