Description
Technical field
The utility model relates to steel reinforced concrete shear walls, belongs to technical field of structural engineering.
Background technology
Shear wall is for bearing the body of wall of vertical load and lateral load in building structure, and wall end does not allow to arrange the edge of a wing
Or during bright post, generally use the wall section pattern of yi word pattern.The ordinary reinforced concrete mid-rise shear wall in yi word pattern cross section is erecting
Easily first produce diagonal crack, the pressure of concrete near Cyclic Loading bottom web diagonal crack to pressure and horizontal loading bottom web district
Broken and peeling causes brittle break, and shear fails pattern makes such body of wall show poor anti-seismic performance.General in order to improve
The anti-seismic performance of logical reinforced concrete wall, arranges steel reinforced concrete sleeper or concrete filled steel tube cylindricality in shear wall both sides of the edge
Become constraint frame.Shear span ratio is less than to middle height and the low-rise shear wall of 2, constraint frame and inefficacy under earthquake for the body of wall web
Order is the principal element determining wall damage pattern and anti-seismic performance.
Use in current architectural engineering for the steel reinforced concrete shear walls of the built-in vertical shaped steel of both sides of the edge component is more
For extensively.When the final failure mode of the steel reinforced concrete mid-rise shear wall in yi word pattern cross section is curved scissors type, shear wall root mixes
There is conquassation and the peeling of continuation in solidifying soil under drawing-press cyclic load, causes member bottom section to bear axial pressure-moment of flexure-shearing
Coefficient effective cross-sectional area gradually weakens, and occurred level crack is through suddenly cuts because of the effect of cutting of the pressure of compressive region for body of wall
Cut through bad, present poor ductile deformation's ability.
Concrete filled steel tube at steel casing pack concrete, the steel sleeve concrete at concrete component encased steel plate
Structure has been obtained for substantial amounts of research and application in civil engineering.Concrete filled steel tube and steel sleeve xoncrete structure are equal
It is that the lateral expansion utilizing its inner concrete of steel tube confinement deforms, thus provide suitable enclosing to the concrete component side of pressurized
Pressure, is in three axle pressured states by making concrete, thus improves peak value compression and the compressive ultimate strain of concrete.Steel bushing
Pipe concrete structure is with the difference of concrete filled steel tube, the concrete parts one that steel sleeve self is not retrained with it
Acting the pressure effect undertaking along component axis direction, the only transversely deforming to concrete retrains reliably.
Content of the invention
The purpose of this utility model is to provide a kind of steel reinforced concrete shearing entering row constraint to body of wall two ends root area
Wall, this steel reinforced concrete shear walls has easy construction, the feature that shock resistance is strong, cost is low, is particularly suitable for use with one
Font cross section, Qiang Duan sleeper district are configured with the steel reinforced concrete mid-rise shear wall of vertical shaped steel.
The steel reinforced concrete shear walls entering row constraint to body of wall two ends root area that the utility model proposes, is at shearing
Wall two ends are close to shaped steel root and are provided with steel bushing, and steel bushing forms confining region, shaped steel root to the concrete bottom body of wall two ends
Being positioned at concrete in restraint area, sidewise restraint effect improves compressive ultimate strength and the compressive ultimate strain of concrete, thus carries
The overall crooked deformability of high-rise shear wall.Stretch into bottom steel bushing body of wall basis, built-in length be thickness of wall body two/
One, thus improve the shear resistance of body of wall, it is to avoid there is through failure by shear in body of wall root；Steel bushing stretches into foundation and can use
Oilpaper etc. are isolated with periphery concrete, it is to avoid sleeve participates in tension, and the deformability affecting tension side shaped steel plays.Divide in body of wall
The transverse steel of cloth and sleeper district vertical reinforcement can penetrate in steel bushing, and body of wall and steel bushing concrete in restraint area pour simultaneously
Formed.The thickness of steel bushing is identical with thickness of wall body, and height and width according to detailing requiments or calculate determination.
The thickness of described steel bushing is identical with the thickness of body of wall, height and width according to following principle by detailing requiments or based on
Calculate and determine: avoid body of wall root to occur concentrating through failure by shear, it is to avoid to concentrate and in through failure by shear, move to steel bushing top
Position.
Described steel bushing is by steel batten plate, the leading flank in vertical wall body thickness direction and the trailing flank steel imbedding body of wall medial surface
Plate is formed by connecting by welding or bolt with the steel plate being positioned at two lateral surfaces of body of wall left or right.Steel bushing imbeds body of wall medial surface
Steel batten plate genesis analysis have polylith, leave space between them, form the perforate passing through for horizontal reinforcement.Steel bushing foot to be had
Enough rigidity, it is ensured that sleeve inner concrete is well retrained.
The utility model is applicable for use with yi word pattern cross section, Qiang Duan sleeper district and is configured with in the steel reinforced concrete of vertical shaped steel
High-rise shear wall, failure mode under lateral action for the body of wall is that flexure type destroys or curved scissors type destroys.The utility model is inapplicable
Low-rise shear wall based on shear compression failure.
The utility model has the advantages that:
1st, while keeping yi word pattern cross section steel reinforced concrete shear walls original advantage, utilize steel bushing to body of wall two ends
Root area enters row constraint, thus prevents body of wall root area under lateral load from the phenomenon that conquassation is peeled off occur, and improves body of wall and exists
Ductile deformation's ability under earthquake.
2nd, steel bushing provides Confinement effect for body of wall root restrained district concrete, improves the peak of restrained district concrete
Value compressive strain and compressive ultimate strain, so that the concrete in shear wall web and frame columns region can more preferable compatible deformation；
In body of wall, transversely distributed steelbar and sleeper district vertical reinforcement or shaped steel can penetrate in steel pipe, so that the globality of body of wall is increased
By force.
3rd, steel bushing stretch into foundation can be with oilpaper etc. and the isolation of periphery concrete, it is to avoid sleeve participates in tension, impact
The deformability of tension side shaped steel plays.Bottom steel bushing in buried foundation, steel bushing cross section participates in shearing resistance effect, can improve
The shear resistance of body of wall, postpones or avoids body of wall generation failure by shear.
4th, the volume of steel bushing constraint body of wall two ends root area is less compared with body of wall volume, the extra steel number increasing
Measuring relatively fewer, compared with other engineering measures with enhanced type steel concrete shear force wall shock resistance, economy is notable, it is simple to
Popularization and application in engineering.
