Abstract
A shear wall of reinforced concrete with sandwich pattern plates and hidden trusses is disclosed, which is aimed at decreasing its-weight, material consumption and cost in the prerequisite of meeting the bearing and earthquake-resistant properties. In addition, its staged bearing capability and variable performance in rigidity, elasticity and plasticity can be designed to a certain extent as required to increase the earthquake-resistant and anti-wind capability of building.
Description
The invention provides a kind of shear wall of reinforced concrete with sandwich pattern plates and hidden trusses, particularly its purpose is under the performance requirement that satisfies the load-bearing antidetonation, and weight reduction to reduce the material usage of building integral, reduces the manufacturing cost of building.In addition, this shear wall as required can be to a certain extent, design it rigidity, elasticity and plasticity interim load-carrying properties and change performance, the ability of carrying with the antidetonation that improves building and wind resistance.
Shear wall is the necessary component of highrise building system.Reinforced concrete shear wall is the best shear wall of the ratio of performance to price in the current building type.But the heavy property of solid shear force wall reinforcing steel bar concrete shear force wall has increased cost and the technical difficulty of reinforced concrete building to high development, and this is one of its major defect.In addition, solid reinforced concrete shear wall often, tends to rigidity at state that can load-bearing, and this is disadvantageous for the destruction of bearing violent earthquake.
The fairly perfect theory of current shear walls design institute foundation is elastic theory and rigid plastic theory, the shape that can calculate mainly be in bar, rigid frame, truss, plate, the plate simple bore, etc. stressed, the stressed change procedure of simple shape and the limit of damage.Owing to be familiar with comprehensively not enough to concrete load-bearing property, many aspects of the key property of reinforced concrete member all are based upon on the basis of experimental data.
The present invention is to be that inference is carried out on the basis according to some learning concepts, the invention of the concept type of foundation and basic manufacture.Because, even if the thinking that the mechanics method of the design of routine building in the past and calculating are dealt with problems also must be relied on concrete engineering entity.Typical empirical formula also will be with the engineering of numerous particular types as carrier.The application practice of their operability needs to obtain data by the test of standard, sets up general empirical formula by general theory of mechanics.
The supporting capacity of reinforced concrete shear wall, rigidity and crack resistance normally design and calculate with ultimate limit state and Theory of Limit Analysis.The ultimate limit state notion mainly is to rely on experimental data.Theory of Limit Analysis mainly contains the theoretical and film effect theory of yield line.
The yield line theory is thought, the structural member of steel concrete when destroyed, according to difformity, can present more well-regulated narrow yield band.Destroy and at first on these yield bands, take place.It also has experimental evidence.
The notion of film effect is to be shown that by existed test results be subjected under the condition of horizontal restraint on the support border, the ultimate bearing capacity of the tabular structural element of concrete will be several times as much as the ultimate bearing capacity that the border is not subjected to the plate of horizontal restraint.The reason of this phenomenon is the platy structure of steel concrete, the neutral axis in simple bending cross section, and its position is in close proximity to the surface of plate when critical destruction, thereby under the effect of simple bending square, the plate midplane is positioned at the tensile region, and it draws distortion with generation.If this neutral axis can not leave the central authorities of plate depth of section, plate can not produce bending, can not produce deformation failure like this.And two surfaces of plate, since the constraint of fringe conditions, the support of bearing, and the counter-force of the tension and compression of two surface correspondences is stoping departing from of neutral axis just.So produced the bigger supporting capacity of self tensile and compressive property than the plate that does not have edge-restraint condition.
Though in the reinforced concrete shear wall, the ratio of the reinforcing bar of layout is very low, generally below 5 percent,, in the design of the Limit Analysis of building, think that they are rigid-plastic materials.Concrete is a rigid element, and reinforcing bar is firm plasticity part.But, the load-bearing property of reinforcing bar, than the high several times of concrete, thereby, can think that under general situation, the importance of reinforcing bar aspect load-bearing is higher than concrete.Like this, can think, reinforcing bar and concrete bound fraction are the representative parts of plasticity, rigidity and the firm plasticity of reinforced concrete structure, the load-carrying properties of reinforced concrete structure are mainly born by this part, so, as long as keep the structure of this part, remove the pure concrete part of middle part between the reinforcing bar, will still have main supporting capacity.If, strengthen support again to this part structure, the integrated carrying ability of this structure will meet or exceed the supporting capacity of solid reinforced concrete shear wall.This is a reason that adopts dark trussed construction.
If think that reinforcing bar is the factor of the main supporting capacity of reinforced concrete shear wall, thereby, improve supporting capacity, and increased the cost of this shear wall also do not have real value by increasing the consumption of reinforcing bar.So, under the cloth muscle rate condition suitable, improve the performance of this shear wall with steel using amount, just can reach the purpose that reduces cost.The ratio of minimizing level, vertical cloth muscle increases the cloth muscle of other directions, is a class mode.
Shear wall is when bearing shear stress, and the ability that the ability that shear stress is born in its pressure aspect, specific thrust aspect are born shear stress is in general stronger.This is that the performance of the tensile pressure ratio of reinforcing bar and concrete material causes.So, under the condition of certain cloth muscle rate, suitably increase the lacing wire ratio, reduce the beading ratio, be the possible mode that increases shear wall integrated carrying performance.But, reduce beading merely, can reduce the vertical plasticity of shear wall, increase the shortcoming that vertical fragility fractures.At this weakness, be example with the rectangle shear wall, increase the layout of the cornerwise and oblique bearing capacity of rectangle, can increase the contact of the level and the vertical bearing ability of armored concrete slab, increase the mutual support of examining tensile behavior and pressurized performance, thereby, whole supporting capacity can be increased.
According to above consideration, the present invention reforms for solid board-like shear wall.It uses light-duty sandwich mould, shear wall inside is constituted the dark trussed construction of being made up of reinforcing bar and concrete, when guaranteeing load-carrying properties, to alleviate the weight of shear wall.In general, the cloth muscle mode of reinforced concrete structure shear wall adopts the mode of horizontal vertical formula more, and what form on the whole is the rectangular frame group.They are how much varistructures.Supporting them and do not change the part of shape, is the pure concrete part in the middle of the framework.When removing pure concrete part, their supporting capacity can significantly reduce.But if increase support bar oblique or the diagonal angle line style, they just can form constant structure how much, thereby have strengthened their supporting capacity.In addition, the front is talked about, increase the layout of the cornerwise and oblique steel concrete rod member of rectangle, can increase the contact of the level and the supporting capacity between the vertical steel reinforced concrete rod member of steel concrete, increase the mutual support of examining tensile behavior and pressurized performance.So, remove after the middle concrete part of truss, need only the supporting capacity of reasonably arranging each rod member, just can guarantee the supporting capacity of shear wall integral body.
According to the yield line theory, the destruction of platy structure is from yield band clocklike.Here, the types of damage of yield band is assumed to isotropic destruction, for any point, the humidification of the layout reinforcing bar of any direction is all identical.Thereby, along these yield band cloth muscle, be easy and the most economic mode.According to the shape and the opening mode of shear wall, the canonical form of coupling beam and many walls limb through overtesting, obtains the typical law of yield band.Through designing and calculating, and prolonging the structure that yield band is arranged reinforcing bar and dark truss, is the another kind of measure that increases this shear wall supporting capacity.
The notion of respective panels, sandwich mould is equivalent to perforate, and has been out many holes and angular mouth.According to the stressed notion of plate, stress will concentrate on the weakest part like this.And the problem of porous in the calculating of mechanics, is insoluble problem.Changing the angle of looking at problem, is to simplify complicated necessary means.If the notion of corresponding truss just can not considered the problem of opening,, just can reach the purpose of the performance of whole load-bearing antidetonation as long as consider the supporting capacity of steel concrete rod member.The designing and calculating of the dark truss part of the dark truss shear wall of sandwich mould is considered by the notion of truss.
With reference to the multi-ribbed plate superstructure, it has removed the concrete of the mid portion of reinforcing bar tension, does not influence the performance that it mainly relies on the part in tension of reinforcing bar.Shear wall bears shearing with plate face direction, and its tensile property is stronger, and this performance itself just less relies on the concrete of falling part.And the concrete of this part also is the burden of pulling force.The concrete of the mid portion between the reinforcing bar of shear wall except bearing pulling force, is also bearing pressure.But, shear wall is except under the situation of special external destructive power effect, normal service load is lower than ultimate load, and the reinforcing bar that the concrete in the middle of not having supports bears ability in the truss pressure-bearing of concrete bound fraction, may be competent at this task fully.Under the situation of the special external force effect of the powerful wind and snow load of the earthquake of height degree of splitting and overburden, slight damage is inevitable, and the pure concrete part in the middle of removing between each steel concrete joint portion, can also be designed to increase the dark truss of the plasticity of shear wall, increase the whole ductility of building, be of value to and reduce whole heavy damage.
Stirrup is playing an important role aspect the plasticity that increases reinforced concrete structure.It can improve and improve the load-carrying properties in the ductility stage of the plastic strain that reinforced concrete structure destroys in the early stage.As long as on respect to the arrangement of the reinforcing bar of two metopes, rationally arrange stirrup, just can guarantee the load-carrying properties of the dark truss of steel concrete.In addition, the dark truss of the steel concrete of diagonal and oblique layout, also quite a kind of configuration mode of special stirrup.It can produce the whole balanced effect of coordinating to the integrally-built load-carrying properties of this heterogeneous material of steel concrete.
In order to obtain the load-carrying properties of film effect, guarantee the bulk strength of shear wall, make it be not only a truss, and, also be a kind of structure of plate, so, on the two sides as metope of truss, constructed two tabular.Because shear wall is the thin plate that is assumed that a plane on design calculation theory, it has, and the respective panels midplane is parallel to be damaged by pressure and bending failure two kinds may.The former can arrange the mode of dark truss by prolonging yield band with reference to the yield line theory, obtains solution to a certain degree.And these two metopes are exactly the reference thin film effect theory, and the relative pulling force and the pressure that produce when the bending by them to the prevention of the axial plate surface offsets of neutrality, obtain the bearing capacity of the plate that produced by resistant to bending performance.
The effect of these two tabular metopes is the booster actions to trussed construction.Its carrying purposes can design outside the safe bearing capacity of normal load.The proper working load performance can partly be born by truss.Two tabular metopes only work to delay this shear wall from the conversion to the deformation failure stage of plasticity of rigidity and flexible normal work stage.And under serious outside destroy, it can be designed to again to be easy to generate, and fragility damages, and do not influence the ductility of truss part.
According to the notion of film effect, shear wall should increase rigidity elasticity, and reduces plasticity, and being of value to like this increases the load-carrying properties that film effect produces.This just need relatively reduce cloth muscle rate.And the reinforcing bar content of two metopes is to regulate by thin and thick, shape and the position of sandwich mould.This requirement has also considerably increased the cloth muscle rate of dark truss, is useful to the supporting capacity of truss.
The relation of the platy structure of metope and dark truss may be thought of as the relation of mutual enhancing.Because the different geometry that truss member constitutes, it is uneven making this enhancing.And adjust the shape of sandwich mould respective side, can improve the equilibrium relation of this mutual support.
The generation of film effect needs shear wall to have thin thickness.Thickness is bigger, near under the limiting pressure, if crooked tendency still do not occur, just can not produce film effect.And this requirement is consistent with the design concept of the weight that alleviates building.
The yield line theory for the reinforced concrete structure of rigid-plastic material, increases cloth muscle rate, is useful to its firm plasticity.For the film effect theory, need to reduce the cloth muscle rate of calculating gained by firm plasticity notion again.And dark truss need be under the condition that does not increase cloth muscle rate, and minimizing level and vertical cloth muscle increase oblique and cornerwise cloth muscle, thereby can promptly coordinate their relation, have satisfied needs separately again, reaches the result who increases the shear wall overall performance.Simultaneously, the dark truss shear wall of sandwich mould is structurally distinguished cloth muscle zone to some extent, and truss is high cloth muscle district, and the plate face is low cloth muscle district, thereby can be optimally in conjunction with the two kinds of theoretical usefulness that disclose in front.
The design philosophy of this shear wall is that the combination with different particularity overcomes simple unified shortcoming.Thereby this shear wall can be designed to the separation structure function on supporting capacity.Place, its edge of a wing, with the solid cylinder and the beam at the wall limb edge of superstructure junction and opening, be the important supporting capacity part of this shear wall; Be the dark trussed construction that metope strengthens then, they and beam column are shared main load; Be two once more the film effect metope is arranged; The performance of the dark truss part of the plastic strain that secondly is the generation of metope when being damaged again.If be regardless of functional structure, it is exactly a kind of form feature with plate, by the truss of plate enhancing.
The limit of building destroys that main what consider is not the ability that the normal operating conditions of building is born static load, but the dynamic loading that earthquake and blast vibration cause.The security performance before the collapse state of collapsing of the integral body of building is by the suitable firm solid cylinder in shear wall end, more weak solid beam relatively, still keeps the shear wall of certain supporting capacity partly to keep under the plastic state.
The character of solid shear wall is tended to monistic rigidity, under the situation of powerful destructive power, antiarch may occur and destroy and serious hard breakdown.The dark truss shear wall of sandwich mould can be designed to interim firm plasticity.In the initial stage of destructive power, it has normal supporting capacity, shows as rigidity; When destructive power tentatively surpassed normal supporting capacity, the humidification of film effect occurred, and continues to keep rigidity or flexible supporting capacity; When serious destructive power occurred, it changed to plasticity, still, since the enhancing mode of multidirectional cloth muscle, the mode of special stirrup, and in the plastic stage, it still has certain supporting capacity.
Because shear wall itself quite is light-duty hollow, and the end of each coupling part is solid, the intensity that this just equals to have strengthened relatively whole beam column aspect has increased the load-carrying properties of building.
In addition, because shear wall has alleviated self and the overall weight of building, thereby the interaction of the internal force when having reduced to destroy, like this, help under lower cost, increase each end of shear wall of building, the anti-seismic performance that the beam column part of suitable beam column part of frame shear wall and frame shear wall structure is arranged, and improve the antidetonation grade of building.
The manufacturing of the shear wall of this structure is with common templates, mould, and sandwich mould builds up one to the bar pouring that arranges the position.He can integral cast-in-situ, also can make prefabricated units.
Whole shear wall of reinforced concrete with sandwich pattern plates and hidden trusses is bundled on the steel bar framework that arranges bearing structure by sandwich mould is installed system exactly, and monobloc cast or manual block are smeared produced.This also is that inner moulding form needs sandwich reason.
Shear wall of reinforced concrete with sandwich pattern plates and hidden trusses can use common templates to build.Also can improve the technology that sandwich mould is installed a little, make with common prefabricated component equipment.
In order to guarantee the closely knit of concrete structure, between sandwich mould and the bar construction, design has the passage that vibrates.
The manufacture method of sandwich mould is, uses lightweight material, and through processing and forming, the configuration flexibility or rigidity is installed attachment, and the surface adds that waterproof layer makes.For example: with expanded perlite and cement, install and use the flexibility or rigidity attachment, make by mould; Perhaps, on the foam glass cellucotton after making mould shapes, the flexibility or rigidity attachment is installed, is applied cement mortar or gypsum, wait organic and inorganic glue connection thing to make.
Because sandwich mould is cast in shear wall inside, the position after their moulding is difficult to detect.They are equivalent to again at the shear wall split shed, and their position is most important to the supporting capacity of shear wall.So the installation attachment of sandwich mould should be the position that can firmly determine sandwich mould, fixing back itself forms the structure near the similar stirrup effect of how much constant shapes.
Shear wall of reinforced concrete with sandwich pattern plates and hidden trusses is in the end of the edge of a wing part that combines with the shear wall of other directions, and the structure of the end that combines with superstructure (floor) is solid structure, is equivalent to solid either overt or covert post, beam.
The edge of opening of wall limb opening increases the density of dark truss, with the intensity of the whole metope of balance.
The design on the edge of a wing according to the property of this shear wall, through overtesting, is carried out designing and calculating and is determined.
The mode that the present invention realizes is: prefabricated and cast-in-place building no matter, all be can be in the molding structure inside of the template of routine, according to experimental data and theoretical designing requirement of calculating, arrange anyhow reinforcing bar and corresponding stirrup to, oblique, diagonal, sandwich mould is installed on steel bar framework again, is carried out the concreting moulding then and finish.
Vibrate size, profile of sandwich mould is the thickness of needs, two panels face according to the size of dark truss, the passage that vibrates and contains reinforcing bar amount comprehensive Design.
The manufacture method of sandwich mould is, uses lightweight material, and through processing and forming, the configuration flexibility or rigidity is installed attachment, and the surface adds that waterproof layer makes.For example: with expanded perlite and cement, install and use the flexibility or rigidity attachment, make by mould; Perhaps, on the foam glass cellucotton after making mould shapes, the flexibility or rigidity attachment is installed, is applied cement mortar or gypsum, wait organic and inorganic glue connection thing to make.
The form of construction work of this shear wall, except the reinforcing bar that will settle oblique or diagonal with strictly bundle to be installed be the sandwich mould, other form of construction work, basic identical with the form of construction work of the reinforced concrete shear wall of routine.Thereby, we can say that it remains a kind of shear wall manufacture of easy construction.
